kill.  
3.a. The electrode and work (or ground) circuits  
are electrically “hot” when the welder is on.  
Do not touch these “hot” parts with your bare  
skin or wet clothing. Wear dry, hole-free  
gloves to insulate hands.  
4.b. Use suitable clothing made from durable flame-resistant  
material to protect your skin and that of your helpers from  
the arc rays.  
3.b. Insulate yourself from work and ground using dry insulation.  
Make certain the insulation is large enough to cover your full  
area of physical contact with work and ground.  
4.c. Protect other nearby personnel with suitable, non-flammable  
screening and/or warn them not to watch the arc nor expose  
themselves to the arc rays or to hot spatter or metal.  
In addition to the normal safety precautions, if welding  
must be performed under electrically hazardous  
conditions (in damp locations or while wearing wet  
clothing; on metal structures such as floors, gratings or  
scaffolds; when in cramped positions such as sitting,  
kneeling or lying, if there is a high risk of unavoidable or  
accidental contact with the workpiece or ground) use  
the following equipment:

fumes and gases. When welding, keep  
your head out of the fume. Use enough  
ventilation and/or exhaust at the arc to keep

fumes and gases away from the breathing zone. When  
welding with electrodes which require special  
ventilation such as stainless or hard facing (see  
instructions on container or MSDS) or on lead or  
cadmium plated steel and other metals or coatings  
which produce highly toxic fumes, keep exposure as  
low as possible and within applicable OShA PEL and  
ACGIh TLV limits using local exhaust or mechanical  
ventilation. In confined spaces or in some circum-  
stances, outdoors, a respirator may be required.  
Additional precautions are also required when welding  
on galvanized steel.  
3.c. In semiautomatic or automatic wire welding, the electrode,  
electrode reel, welding head, nozzle or semiautomatic  
welding gun are also electrically “hot”.  
3.d. Always be sure the work cable makes a good electrical  
connection with the metal being welded. The connection  
should be as close as possible to the area being welded.  
3.e. Ground the work or metal to be welded to a good electrical  
(earth) ground.  
3.f. Maintain the electrode holder, work clamp, welding cable and  
welding machine in good, safe operating condition. Replace  
damaged insulation.  
5. b. The operation of welding fume control equipment is affected  
by various factors including proper use and positioning of  
the equipment, maintenance of the equipment and the spe-  
cific welding procedure and application involved. Worker  
exposure level should be checked upon installation and  
periodically thereafter to be certain it is within applicable  
OSHA PEL and ACGIH TLV limits.  
3.g. Never dip the electrode in water for cooling.  
3.h. Never simultaneously touch electrically “hot” parts of  
electrode holders connected to two welders because voltage  
between the two can be the total of the open circuit voltage  
of both welders.  
5.c. Do not weld in locations near chlorinated hydrocarbon vapors  
coming from degreasing, cleaning or spraying operations.  
The heat and rays of the arc can react with solvent vapors to  
form phosgene, a highly toxic gas, and other irritating prod-  
ucts.  
3.i. When working above floor level, use a safety belt to protect  
yourself from a fall should you get a shock.  
3.j. Also see Items 6.c. and 8.  
5.d. Shielding gases used for arc welding can displace air and  
cause injury or death. Always use enough ventilation,  
especially in confined areas, to insure breathing air is safe.  
5.e. Read and understand the manufacturer’s instructions for this  
equipment and the consumables to be used, including the  
material safety data sheet (MSDS) and follow your  
employer’s safety practices. MSDS forms are available from  
your welding distributor or from the manufacturer.

the welding sparks from starting a fire.  
regulators designed for the gas and  
pressure used. All hoses, fittings, etc. should be suitable for  
the application and maintained in good condition.  
Remember that welding sparks and hot  
materials from welding can easily go through small cracks  
and openings to adjacent areas. Avoid welding near  
hydraulic lines. Have a fire extinguisher readily available.  
7.b. Always keep cylinders in an upright position securely  
chained to an undercarriage or fixed support.  
6.b. Where compressed gases are to be used at the job site,  
special precautions should be used to prevent hazardous  
situations. Refer to “Safety in Welding and Cutting” (ANSI  
Standard Z49.1) and the operating information for the  
equipment being used.  
7.c. Cylinders should be located:  
Away from areas where they may be struck or subjected to  
physical damage.  
•A safe distance from arc welding or cutting operations and  
any other source of heat, sparks, or flame.  
6.c. When not welding, make certain no part of the electrode  
circuit is touching the work or ground. Accidental contact  
can cause overheating and create a fire hazard.  
7.d. Never allow the electrode, electrode holder or any other  
electrically “hot” parts to touch a cylinder.  
6.d. Do not heat, cut or weld tanks, drums or containers until the  
proper steps have been taken to insure that such procedures  
will not cause flammable or toxic vapors from substances  
inside. They can cause an explosion even though they have  
been “cleaned”. For information, purchase “Recommended  
Safe Practices for the Preparation for Welding and Cutting of  
Containers and Piping That Have Held Hazardous  
Substances”, AWS F4.1 from the American Welding Society  
(see address above).  
7.e. Keep your head and face away from the cylinder valve outlet  
when opening the cylinder valve.  
7.f. Valve protection caps should always be in place and hand  
tight except when the cylinder is in use or connected for  
use.  
7.g. Read and follow the instructions on compressed gas  
cylinders, associated equipment, and CGA publication P-l,  
“Precautions for Safe Handling of Compressed Gases in  
Cylinders,” available from the Compressed Gas Association  
1235 Jefferson Davis Highway, Arlington, VA 22202.  
6.e. Vent hollow castings or containers before heating, cutting or  
welding. They may explode.  
6.f. Sparks and spatter are thrown from the welding arc. Wear oil  
free protective garments such as leather gloves, heavy shirt,  
cuffless trousers, high shoes and a cap over your hair. Wear  
ear plugs when welding out of position or in confined places.  
Always wear safety glasses with side shields when in a  
welding area.  
FOR ELECTRICALLY  
powered equipment.  
8.a. Turn off input power using the disconnect  
switch at the fuse box before working on  
the equipment.  
6.g. Connect the work cable to the work as close to the welding  
area as practical. Work cables connected to the building  
framework or other locations away from the welding area  
increase the possibility of the welding current passing  
through lifting chains, crane cables or other alternate cir-  
cuits. This can create fire hazards or overheat lifting chains  
or cables until they fail.  
8.b. Install equipment in accordance with the U.S. National  
Electrical Code, all local codes and the manufacturer’s  
recommendations.  
8.c. Ground the equipment in accordance with the U.S. National  
Electrical Code and the manufacturer’s recommendations.  
6.h. Also see item 1.c.

SAFETY  
5. Toujours porter des lunettes de sécurité dans la zone de  
PRÉCAuTIONS DE SÛRETÉ  
soudage. Utiliser des lunettes avec écrans lateraux dans les  
zones où l’on pique le laitier.  
Pour votre propre protection lire et observer toutes les instructions  
et les précautions de sûreté specifiques qui parraissent dans ce  
manuel aussi bien que les précautions de sûreté générales suiv-  
antes:  
6. Eloigner les matériaux inflammables ou les recouvrir afin de  
prévenir tout risque d’incendie dû aux étincelles.  
7. Quand on ne soude pas, poser la pince à une endroit isolé de  
la masse. Un court-circuit accidental peut provoquer un  
échauffement et un risque d’incendie.  
Sûreté Pour Soudage A L’Arc  
1. Protegez-vous contre la secousse électrique:  
a. Les circuits à l’électrode et à la piéce sont sous tension  
quand la machine à souder est en marche. Eviter toujours  
tout contact entre les parties sous tension et la peau nue  
ou les vétements mouillés. Porter des gants secs et sans  
trous pour isoler les mains.  
8. S’assurer que la masse est connectée le plus prés possible  
de la zone de travail qu’il est pratique de le faire. Si on place  
la masse sur la charpente de la construction ou d’autres  
endroits éloignés de la zone de travail, on augmente le risque  
de voir passer le courant de soudage par les chaines de lev-  
age, câbles de grue, ou autres circuits. Cela peut provoquer  
des risques d’incendie ou d’echauffement des chaines et des  
câbles jusqu’à ce qu’ils se rompent.  
b. Faire trés attention de bien s’isoler de la masse quand on  
soude dans des endroits humides, ou sur un plancher  
metallique ou des grilles metalliques, principalement dans  
les positions assis ou couché pour lesquelles une grande  
partie du corps peut être en contact avec la masse.  
c. Maintenir le porte-électrode, la pince de masse, le câble  
de soudage et la machine à souder en bon et sûr état  
defonctionnement.  
9. Assurer une ventilation suffisante dans la zone de soudage.  
Ceci est particuliérement important pour le soudage de tôles  
galvanisées plombées, ou cadmiées ou tout autre métal qui  
produit des fumeés toxiques.  
d.Ne jamais plonger le porte-électrode dans l’eau pour le  
refroidir.  
10. Ne pas souder en présence de vapeurs de chlore provenant  
d’opérations de dégraissage, nettoyage ou pistolage. La  
chaleur ou les rayons de l’arc peuvent réagir avec les vapeurs  
du solvant pour produire du phosgéne (gas fortement toxique)  
ou autres produits irritants.  
e. Ne jamais toucher simultanément les parties sous tension  
des porte-électrodes connectés à deux machines à souder  
parce que la tension entre les deux pinces peut être le  
total de la tension à vide des deux machines.  
f. Si on utilise la machine à souder comme une source de  
courant pour soudage semi-automatique, ces precautions  
pour le porte-électrode s’applicuent aussi au pistolet de  
soudage.  
11. Pour obtenir de plus amples renseignements sur la sûreté,  
voir le code “Code for safety in welding and cutting” CSA  
Standard W 117.2-1974.  
2. Dans le cas de travail au dessus du niveau du sol, se protéger  
contre les chutes dans le cas ou on recoit un choc. Ne jamais  
enrouler le câble-électrode autour de n’importe quelle partie  
du corps.

3. Un coup d’arc peut être plus sévère qu’un coup de soliel,  
donc:  
a. Utiliser un bon masque avec un verre filtrant approprié  
ainsi qu’un verre blanc afin de se protéger les yeux du ray-  
onnement de l’arc et des projections quand on soude ou  
quand on regarde l’arc.  
1. Relier à la terre le chassis du poste conformement au code de  
l’électricité et aux recommendations du fabricant. Le dispositif  
de montage ou la piece à souder doit être branché à une  
bonne mise à la terre.  
b. Porter des vêtements convenables afin de protéger la  
peau de soudeur et des aides contre le rayonnement de  
l‘arc.  
c. Protéger l’autre personnel travaillant à proximité au  
soudage à l’aide d’écrans appropriés et non-inflammables.  
2. Autant que possible, I’installation et l’entretien du poste seront  
effectués par un électricien qualifié.  
4. Des gouttes de laitier en fusion sont émises de l’arc de  
soudage. Se protéger avec des vêtements de protection libres  
de l’huile, tels que les gants en cuir, chemise épaisse, pan-  
talons sans revers, et chaussures montantes.  
3. Avant de faires des travaux à l’interieur de poste, la debranch-  
er à l’interrupteur à la boite de fusibles.  
4. Garder tous les couvercles et dispositifs de sûreté à leur  
place.

SAFETY  
Electromagnetic Compatibility (EMC)  
Conformance  
Products displaying the CE mark are in conformity with European Community Council Directive of 15 Dec  
2004 on the approximation of the laws of the Member States relating to electromagnetic compatibility,  
2004/108/EC. It was manufactured in conformity with a national standard that implements a harmonized  
standard: EN 60974-10 Electromagnetic Compatibility (EMC) Product Standard for Arc Welding Equipment.  
It is for use with other Lincoln Electric equipment. It is designed for industrial and professional use.  
Introduction  
All electrical equipment generates small amounts of electromagnetic emission. Electrical emission may be  
transmitted through power lines or radiated through space, similar to a radio transmitter. When emissions  
are received by other equipment, electrical interference may result. Electrical emissions may affect many  
kinds of electrical equipment; other nearby welding equipment, radio and TV reception, numerical controlled  
machines, telephone systems, computers, etc. Be aware that interference may result and extra precautions  
may be required when a welding power source is used in a domestic establishment.  
Installation and Use  
The user is responsible for installing and using the welding equipment according to the manufacturer’s  
instructions. If electromagnetic disturbances are detected then it shall be the responsibility of the user of the  
welding equipment to resolve the situation with the technical assistance of the manufacturer. In some cases  
this remedial action may be as simple as earthing (grounding) the welding circuit, see Note. In other cases it  
could involve construction of an electromagnetic screen enclosing the power source and the work complete  
with associated input filters. In all cases electromagnetic disturbances must be reduced to the point where  
they are no longer troublesome.  
Note: The welding circuit may or may not be earthed for safety reasons according to national codes.  
Changing the earthing arrangements should only be authorized by a person who is compe-  
tent to access whether the changes will increase the risk of injury, e.g., by allowing parallel  
welding current return paths which may damage the earth circuits of other equipment.  
Assessment of Area  
Before installing welding equipment the user shall make an assessment of potential electromagnetic prob-  
lems in the surrounding area. The following shall be taken into account:  
a) other supply cables, control cables, signaling and telephone cables; above, below and adjacent to the  
welding equipment;  
b) radio and television transmitters and receivers;  
c) computer and other control equipment;  
d) safety critical equipment, e.g., guarding of industrial equipment;  
e) the health of the people around, e.g., the use of pacemakers and hearing aids;  
f) equipment used for calibration or measurement  
g) the immunity of other equipment in the environment. The user shall ensure that other equipment being  
used in the environment is compatible. This may require additional protection measures;  
h) the time of day that welding or other activities are to be carried out.

SAFETY  
Electromagnetic Compatibility (EMC)  
The size of the surrounding area to be considered will depend on the structure of the building and other  
activities that are taking place. The surrounding area may extend beyond the boundaries of the premises.  
Methods of Reducing Emissions  
Mains Supply  
Welding equipment should be connected to the mains supply according to the manufacturer’s recommenda-  
tions. If interference occurs, it may be necessary to take additional precautions such as filtering of the mains  
supply. Consideration should be given to shielding the supply cable of permanently installed welding equip-  
ment, in metallic conduit or equivalent. Shielding should be electrically continuous throughout its length. The  
shielding should be connected to the welding power source so that good electrical contact is maintained  
between the conduit and the welding power source enclosure.  
Maintenance of the Welding Equipment  
The welding equipment should be routinely maintained according to the manufacturer’s recommendations.  
All access and service doors and covers should be closed and properly fastened when the welding equip-  
ment is in operation. The welding equipment should not be modified in any way except for those changes  
and adjustments covered in the manufacturers instructions. In particular, the spark gaps of arc striking and  
stabilizing devices should be adjusted and maintained according to the manufacturer’s recommendations.  
Welding Cables  
The welding cables should be kept as short as possible and should be positioned close together, running at  
or close to floor level.  
Equipotential Bonding  
Bonding of all metallic components in the welding installation and adjacent to it should be considered.  
However, metallic components bonded to the work piece will increase the risk that the operator could  
receive a shock by touching these metallic components and the electrode at the same time. The operator  
should be insulated from all such bonded metallic components.  
Earthing of the Workpiece  
Where the workpiece is not bonded to earth for electrical safety, not connected to earth because of its size  
and position, e.g., ships hull or building steelwork, a connection bonding the workpiece to earth may reduce  
emissions in some, but not all instances. Care should be taken to prevent the earthing of the workpiece  
increasing the risk of injury to users, or damage to other electrical equipment. Where necessary, the connec-  
tion of the workpiece to earth should be made by a direct connection to the workpiece, but in some countries  
where direct connection is not permitted, the bonding should be achieved by suitable capacitance, selected  
according to national regulations.  
Screening and Shielding  
Selective screening and shielding of other cables and equipment in the surrounding area may alleviate prob-  
lems of interference. Screening of the entire welding installation may be considered for special

RECOMMENDED WORK CAbLE  
SIzES FOR ARC WELDING  
SEMI-AuTOMATIC WELDING  
POLARITY  
A 15 ft. work cable is provided with the POWER  
WAVE® C300. This cable is appropriately sized for all  
of the POWER WAVE® C300’s welding procedures. If  
the work cable needs to be replaced a similar quality  
of cable should be used as excessive voltage drops  
caused by undersized welding cables can result in  
unsatisfactory welding performance. Always use the  
largest work cables that is practical, and be sure all  
connections are clean and tight.  
Most GMAW welding procedures use Electrode  
Positive welding. For these applications, connect the  
wire drive’s connection block to the positive (+) output  
stud and connect the work lead to the negative (-) out-  
put stud.  
Some FCAW-SS does use Electrode Negative  
Polarity. For these applications, connect the wire  
drive’s connection block to the negative (-) output stud  
and connect the work lead to the positive (+) output  
stud.  
Note: Excessive heat in the weld circuit indicates  
undersized cables and/or bad connections.  
REMOTE SENSE LEAD SPECIFICA-  
TIONS  
Since the POWER WAVE® C300 has the ability to be  
in close proximity to the welding arc, the POWER  
WAVE® C300 does not require the use of remote  
sense leads.

CAbLE INDuCTANCE AND ITS  
EFFECTS ON WELDING  
To minimize inductance always use the appropriate  
size cables, and whenever possible, run the electrode  
and work cables in close proximity to one another to  
minimize the loop area. Since the most significant fac-  
tor in cable inductance is the welding loop length,  
avoid excessive lengths and do not coil excess cable.  
For long work piece lengths, a sliding ground should  
be considered to keep the total welding loop length as  
short as possible.  
Whenever possible always weld in a direction  
away from the work (ground) connection.  
Excessive cable inductance will cause the welding  
performance to degrade. There are several factors  
that contribute to the overall inductance of the cabling  
system including cable size, and loop area. The loop  
area is defined by the separation distance between  
the electrode and work cables, and the overall welding  
loop length. The welding loop length is defined as the  
total of length of the electrode cable (A) + work cable  
(B) + work path (C) (see Figure A.3).  
For additional Safety information regarding the  
electrode and work cable set-up, See the standard  
“SAFETY INFORMATION” located in the front of  
this Instruction Manual.

MAKING A WELD WITh WAVEFORM  
TEChNOLOGY POWER SOuRCES  
WELD MODE  
Selecting a weld mode determines the output charac-  
teristics of the Power Wave power source. Weld  
modes are developed with a specific electrode materi-  
al, electrode size, and shielding gas. For a more com-  
plete description of the weld modes programmed into  
the Power Wave at the factory, refer to the Weld Set  
Reference Guide supplied with the machine or avail-  
WARNING  
MAKING A WELD  
The serviceability of a product or structure utiliz-  
ing the welding programs is and must be the sole  
responsibility of the builder/user. Many variables  
beyond the control of The Lincoln Electric  
Company affect the results obtained in applying  
these programs. These variables include, but are  
not limited to, welding procedure, plate chemistry  
and temperature, weldment design, fabrication  
methods and service requirements. The available  
range of a welding program may not be suitable  
for all applications, and the build/user is and must  
be solely responsible for welding program selec-  
tion.  
WIRE FEED SPEED (WFS)  
In synergic welding modes (synergic CV, GMAW-P),  
WFS is the dominant control parameter. The user  
adjusts WFS according to factors such as wire size,  
penetration requirements, heat input, etc. The Power  
Wave then uses the WFS setting to adjust the voltage  
and current according to settings contained in the  
Power Wave.  
---------------------------------------------------------------------  
Choose the electrode material, electrode size, shield-  
ing gas, and process (GMAW, GMAW-P etc.) appro-  
priate for the material to be welded.  
In non-synergic modes, the WFS control behaves like  
a conventional power source where WFS and voltage  
are independent adjustments. Therefore, to maintain  
proper arc characteristics, the operator must adjust  
the voltage to compensate for any changes made to  
the WFS.  
Select the weld mode that best matches the desired  
welding process. The standard weld set shipped with  
the Power Wave C300 encompasses a wide range of  
common processes that will meet most needs. If a  
special weld mode is desired, contact the local Lincoln  
Electric sales representative.  
AMPS  
In constant current modes, this control adjusts the  
welding current.  
All adjustments are made through the user interface.  
Because of the different configuration options your  
system may not have all of the following adjustments.  
Regardless of availability, all controls are described in  
the following section ( See Figure B.4 Panel Controls  
Used)  
VOLTS  
In constant voltage modes, this control adjusts the  
welding voltage.  
TRIM  
In pulse synergic welding modes, the Trim setting  
adjusts the arc length. Trim is adjustable from 0.50 to  
1.50. 1.00 is the nominal setting and is a good start-  
ing point for most conditions.  
DEFINITION OF WELDING MODES  
NON-SYNERGIC WELDING MODES  
• A Non-synergic welding mode requires all welding  
process variables to be set by the operator.  
uLTIMARCTM CONTROL  
UltimArcTM Control allows the operator to vary the arc  
characteristics  
from  
“soft”  
to  
“crisp”.  
SYNERGIC WELDING MODES  
UltimArc™Control is adjustable from –10.0 to +10.0  
with a nominal setting of 0.0.  
• A Synergic welding mode offers the simplicity of  
single knob control. The machine will select the cor-  
rect voltage and amperage based on the wire feed  
speed (WFS) set by the operator.

WELDING  
UltimArc™Control, adjusts the apparent inductance of  
the wave shape. The UltimArc™Control adjustment is  
similar to the “pinch” function in that it is inversely pro-  
portional to inductance. Therefore, increasing  
UltimArc™Control greater than 0.0 results in a crisper  
arc (more spatter) while decreasing the  
UltimArc™Control to less than 0.0 provides a softer  
arc (less spatter).  
In non-synergic modes, the WFS control is similar to a  
conventional CV power source where WFS and volt-  
age are independent adjustments. Therefore to main-  
tain the arc characteristics, the operator must adjust  
the voltage to compensate for any changes made to  
the WFS.

Synergic CV programs feature an ideal voltage best  
suited for most procedures. Use this voltage as a  
starting point and adjust if needed for personal prefer-  
ences.  
GMAW (MIG) SYNERGIC WELDING  
For each wire feed speed, a corresponding voltage is  
preprogrammed into the machine. The nominal pre-  
programmed voltage is the best average voltage for a  
given wire feed speed, but may be adjusted to prefer-  
ence. When the wire feed speed changes, the Power  
Wave automatically adjusts the voltage level corre-  
spondingly to maintain similar arc characteristics  
throughout the WFS range.  
When the voltage knob is rotated, the display will  
show an upper or lower bar indicating if the voltage is  
above or below the ideal voltage.

OPERATION  
STEEL AND STAINLESS SYNERGIC GMAW-P (PuLSED MIG) WELDING  
Trim adjusts the arc length and ranges from 0.50 to  
1.50 with a nominal value of 1.00. Increasing the trim  
value increases the arc length. Decreasing the trim  
value decreases the arc length.  
When pulse welding, the power source primarily regu-  
lates the arc current, not the arc voltage. During a  
pulsing cycle, arc current is regulated from a low  
background level to a high peak level and then back  
down to the low background level. The average arc  
voltage increases and decreases as the average arc  
current is increased or decreased. The peak current,  
back ground current, rise time, fall time and pulse fre-  
quency all affect the average voltage. Since the aver-  
age voltage for a given wire feed speed can only be  
determined when all the pulsing waveform parameters  
are known, a unit less value called “trim” is used for  
adjusting the arc length.  
Pulse welding modes are synergic; using wire feed  
speed as the main control parameter. As the wire  
feed speed is adjusted, the power source adjusts the  
waveform parameters to maintain good welding char-  
acteristics. Trim is used as a secondary control to  
change the arc length for material conditions or indi-  
vidual preference. (See Figure b.5)

The adaptive behavior supports a range of stick outs  
from approximately 1/2” to 1-1/4”. At low or high wire  
feed speeds, the adaptive range may be less due to  
physical limitations of the welding process.  
The Power Wave utilizes adaptive control to compensate  
for changes in the electrical stick-out(distance from the  
contact tip to the work piece) while welding. The Power  
Wave waveforms are optimized for a 5/8” to 3/4” stick out  
depending on the wire type and wire feed speed.

ALuMINuM GMAW-P AND GMAW-PP  
ALuMINuM PuLSE WELDING  
Synergic GMAW-P (Pulsed MIG) welding is ideal for  
low spatter, out of position and reduced heat input  
applications. During pulse welding, the welding cur-  
rent continuously switches from a low level to a high  
level and then back again. Each pulse sends a small  
droplet of molten metal from the wire to the weld pud-  
dle.  
The Power Wave® C300 can produce top quality alu-  
minum welds with excellent appearance, little spatter  
and good bead shape. Push-pull guns are available  
for consistent feeding when welding a long distance  
away from the wire feeder.  
PuLSE-ON-PuLSE WELDING  
Pulse welding controls the arc length with 'Trim'  
instead of voltage. When trim (arc length) is adjusted,  
the Power Wave automatically recalculates the volt-  
age, current and time of each part of the pulse wave-  
form for the best result. Trim adjusts the arc length  
and ranges from 0.50 to 1.50, with a nominal value of  
1.00 for a 3/4" (19mm) electrode stick-out. Trim values  
greater than 1.00 increase the arc length, while values  
less than 1.00 decrease the arc length.  
The Power Wave system offers both traditional pulse  
and Pulse-on-Pulse™. Pulse-on-Pulse (GMAW-PP)  
is an exclusive waveform for aluminum welding. Use  
it to make welds with a "stacked dime" appearance,  
similar to GTAW welds.( See Figure B.7)  
FIGuRE b.7  
(See Figure B.10)  
FIGuRE b.10  
The pulsing frequency is adjustable. Changing the  
Modulation Frequency (or UltimArc™ Control) of the  
waveform changes the ripple spacing. Faster travel  
speeds may be achieved by using higher values of  
Modulation Frequency. ( See Figure B.8 and B.9p)

OPERATION  
TRIGGER  
The 2-Step - 4-Step switch changes the function of  
the gun trigger. 2-Step trigger operation switches the  
welding output ON-OFF in direct response to the trig-  
ger. 4-Step trigger operation provides 'trigger interlock'  
capability and gives the ability to control the amount of  
time spent in the arc start and arc crater steps.  
Press the push button on the case front to toggle  
between 2-Step and 4-Step operation.  
The 2-Step, 4-Step trigger has no effect when weld-  
ing with SMAW.  
2-Step Trigger  
2-Step trigger operation is the most common. When  
the gun trigger is pulled, the welding system (power  
source and wire feeder) cycles through the arc start-  
ing sequence and into the main welding parameters.  
The welding system will continue to weld as long as  
the gun trigger is activated. Once the trigger is  
released, the welding system cycles through the arc  
ending steps  
4-Step Trigger  
4-Step trigger operation gives the welder additional  
control in the welding sequence. 4-Step trigger allows  
the welder to choose the arc start, weld and arc end  
time. It may also be set-up to work as a trigger inter-  
lock.

OPERATION  
ExAMPLE 1 - 2 STEP TRIGGER: Simple operation  
The simplest trigger operation occurs with a 2 Step  
trigger and the Start, Crater and Burnback functions  
all set to OFF. (See Figure B.11)  
For this sequence,  
PREFLOW:  
Shielding gas begins to flow immediately when the  
gun trigger is pulled.  
RuN-IN:  
After preflow time expires, the power source regulates  
to the welding output and wire is advanced towards  
the work piece at the Run-In WFS. If an arc is not  
established within 1.5 seconds, the wire feed speed  
will jump to the welding wire feed speed  
WELD:  
The power source output and the wire feed speed  
continue at the weld settings for as long as the trigger  
is pulled.  
POSTFLOW: As soon as the trigger is released, the  
power source output and the wire feed speed are  
turned OFF. Shielding gas continues until the post  
flow timer expires.

OPERATION  
ExAMPLE 2 - 2 STEP TRIGGER: Improved Arc Start  
and Arc End. Tailoring the arc start and arc end is a  
common method for reducing spatter and improving  
weld quality. This can be accomplished with the Start  
and Burnback functions set to a desired values and  
Crater set to OFF. (See Figure B.12)  
uPSLOPE:  
Once the wire touches the work and an arc is estab-  
lished, both the machine output and the wire feed  
speed ramp to the weld settings throughout the start  
time. The time period of ramping from the start set-  
tings to the weld settings is called UPSLOPE.  
For this sequence,  
PREFLOW:  
Shielding gas begins to flow immediately when the  
gun trigger is pulled.  
WELD:  
After upslope, the power source output and the wire  
feed speed continue at the weld settings.  
buRNbACK:  
RuN-IN:  
As soon as the trigger is released, the wire feed  
speed is turned OFF and the machine output contin-  
ues for the burnback time.  
After preflow time expires, the power source regulates  
to the start output and wire is advanced towards the  
work piece at the Run-In WFS. If an arc is not estab-  
lished within 1.5 seconds, the power source output  
and wire feed speed skips to the weld settings.  
POSTFLOW:  
Next, the machine output is turned OFF and shielding  
gas continues until the post flow timer expires.

ExAMPLE 3 - 2 STEP TRIGGER: Customized Arc  
Start, Crater and Arc End. Sometimes it is advanta-  
geous to set specific arc start, crater and arc ending  
parameters for the ideal weld. Many times when  
welding aluminum crater control is necessary to make  
a good weld. This is done by setting Start, Crater  
and Burnback functions to desired values. (See  
Figure B.13)  
WELD:  
After upslope, the power source output and the wire  
feed speed continue at the weld settings.  
CRATER & DOWNSLOPE:  
As soon as the trigger is released, the wire feed  
speed and power source output ramp to the crater  
settings throughout the crater time. The time period of  
ramping from the weld settings to the crater settings is  
called DOWNSLOPE.  
For this sequence,  
PREFLOW:  
Shielding gas begins to flow immediately when the  
gun trigger is pulled.  
buRNbACK:  
After the crater time expires, the wire feed speed is  
turned OFF and the machine output continues for the

POSTFLOW:  
Next, the machine output is turned OFF and shielding  
gas continues until the post flow timer expires.  
START & uPSLOPE:  
As soon as the trigger is pulled, this starts preflow.  
The Strike arc established, Start time, and Upslope  
parameters are used at the beginning of the weld  
sequence to establish a stable arc and provide a  
smooth transition to the weld settings.

OPERATION  
ExAMPLE 4 – 4 STEP TRIGGER: Trigger Interlock  
The 4 step trigger can be configured as a trigger inter-  
lock. Trigger interlock adds to the welder’s comfort  
when making long welds by allowing the trigger to be  
released after an initial trigger pull. Welding stops  
when the trigger is pulled a second time and then  
released, or if the arc is interrupted. (See Figure B.14)  
For this sequence,  
PREFLOW:  
Shielding gas begins to flow immediately when the  
gun trigger is pulled.  
RuN-IN:  
After preflow time expires, the power source regulates  
to the welding output and wire is advanced towards  
the work piece at the Run-In WFS. If an arc is not  
established within 1.5 seconds, the wire feed speed  
will jump to the welding wire feed speed.  
WELD:  
The power source output and the wire feed speed  
continue at the weld settings. Welding continues when  
the trigger is pulled a second time.  
POSTFLOW:  
As soon as the trigger is released for the second time,  
the power source output and the wire feed speed are  
turned OFF. Shielding gas flows until the post flow  
timer expires.

OPERATION  
uPSLOPE:  
ExAMPLE 5 - 4 STEP TRIGGER: Manual control of  
Start and Crater times with Burnback ON. The 4 step  
trigger sequence gives the most flexibility when the  
Start, Crater and Burnback functions are active. This  
is a popular choice when welding aluminum because  
extra heat may be needed during Start and less heat  
desired during crater. With 4 step trigger, the welder  
chooses the amount of time to weld at the Start, Weld  
and Crater settings by using the gun trigger. Burnback  
reduces the occurrence of wire to sticking into the  
weld pool at the end of a weld and conditions the end  
of the wire for the next arc start. ( See Figure B.15)  
During upslope, the power source output and the wire  
feed speed ramp to the weld settings throughout the  
start time. The time period of ramping from the start  
settings to the weld settings is called UPSLOPE.  
WELD:  
After upslope, the power source output and the wire  
feed speed continue at the weld settings.  
DOWNSLOPE:  
As soon as the trigger is pulled, the wire feed speed  
and power source output ramp to the crater settings  
throughout the crater time. The time period of ramp-  
ing from the weld settings to the crater settings is  
called DOWNSLOPE.  
In this sequence,  
PREFLOW:  
Shielding gas begins to flow immediately when the  
gun trigger is pulled.  
CRATER:  
During CRATER, the power source continues to sup-  
ply output at the crater WFS and voltage.  
RuN-IN:  
After preflow time expires, the power source regulates  
to the start output and wire is advanced towards the  
work piece at the run-in WFS. If an arc is not estab-  
lished within 1.5 seconds, the power source output  
and wire feed speed skips to the weld settings.  
buRNbACK:  
When the trigger is released, the wire feed speed is  
turned OFF and the machine output continues for the  
burnback time.  
START:  
The power source welds at the start WFS and voltage  
until the trigger is released.  
POSTFLOW:  
Next, the machine output is turned OFF and shielding  
gas continues until the post flow timer expires.

OPERATION  
3. Operation with POWER WAVE® C300:  
COLD FEED/GAS PuRGE SWITCh  
Install the spool gun per the installation instructions  
COLD FEED  
Turn the Power Wave® C300 input power ON.  
Make sure the machine is configured for spool gun  
operation (see parameter P.17 in the Set-up Menu sec-  
tion).  
Cold Feed and Gas Purge are com-  
bined into a single spring centered tog-  
gle switch.  
Pull and release the trigger of the Spool Gun. The  
Power Mig recognizes the spool gun as active and weld  
parameters are adjustable for welding with the Spool  
Gun.  
GAS PURGE  
To activate Cold Feeding, hold the  
switch in the FORWARD position. The  
wire drive will feed electrode but neither the power  
source nor the gas solenoid will be energized. Adjust  
the speed of cold feeding by rotating the WFS knob.  
Cold feeding, or "cold inching" the electrode is useful  
for threading the electrode through the gun.  
Non-Synergic Weld Modes (Mode 5)  
Voltage is adjustable at the power source. The  
right control knob on the power source will  
adjust the voltage that is displayed in the meter  
directly above it.  
Hold with toggle switch in the bACK position to acti-  
vate Gas Purge and let the shielding gas flow. The  
gas solenoid valve will energize but neither the power  
source output nor the drive motor will be turned on.  
The Gas Purge switch is useful for setting the proper  
flow rate of shielding gas. Flow meters should always  
be adjusted while the shielding gas is flowing.  
The left Display (WFS / AMPS) on the Power  
Wave® C300 will have 4 dashes (----) to indi-  
cate that the left control knob on the power  
source is inactive. Wire Feed Speed is set at  
the Spool Gun.  
SPOOL GuN OPERATION  
The following procedure settings for Aluminum  
4043 can be used as initial settings for making  
test welds to determine final settings:  
When the Power Wave® C300 Gun is configured for  
Spool Gun Operation (see parameter P.17 in the Set-up  
Menu section), the Power Wave® C300 provides gun  
trigger switch transfer between the Built-in gun or the  
spool gun for the same polarity welding with different  
wire and gas processes.

4. Synergic Weld Modes  
Closing either gun trigger will cause the electrode of  
both guns to be electrically “hOT”. be sure unused  
gun is positioned so electrode or tip will not contact  
metal case or other metal common to work.  
The Power Wave® C300 is designed to enable syner-  
gic weld modes and synergic pulse processes with the  
spool gun. The actual wire feed speed (WFS) of the  
spool gun must be measured and manually set on the  
Power Wave® C300 as a work point for the Power  
Wave® C300 (SPD).  
---------------------------------------------------------------------------  
Because the control circuitry senses each gun through its  
trigger leads, weld parameters are displayed and  
adjustable for the last gun that was triggered.  
In synergic modes when the spool gun trigger is  
pulled, an adjustable value for the SPD work  
point is displayed in the left meter. The letters  
SPD are displayed in the right meter.  
1. Pulling the trigger for the built-in feeder gun:  
Disables spool gun operation.  
Changes the displays of the Power Wave® C300  
to correspond to feeder gun operation.  
The left control knob adjusts the SPD value.  
The right control knob is inactive.  
Closing feeder gun trigger starts feeder gun weld-  
ing and makes both electrodes electrically “HOT”.  
Measure the actual WFS, in inches per minute,  
at the spool gun and set the SPD at the Power  
Wave® C300 to match this value. WFS can be  
measured by pulling the trigger of the spool gun  
and feeding wire for 6 seconds. Measure the  
length of wire (in inches) that was fed and multi-  
ply by 10.  
2. Pulling SPOOL GuN Trigger:  
Disables built-in feeder gun operation.  
Changes the displays of the Power Wave® C300  
to correspond to Spool Gun operation.  
Closing spool gun trigger starts spool gun welding  
and makes both electrodes electrically “HOT”.

OPERATION  
The Power Wave® C300 is now configured and  
ready to weld in the synergic mode.  
Adjustment of the SPD value from the set value  
has the affect of adjusting trim or arc length.  
To increase the arc length; increase the SPD  
value at the Power Wave® C300 to a value  
higher than the actual WFS.  
Remember; do not change the WFS at the spool  
gun.  
• To decrease the arc length; decrease the SPD  
value at the Power Wave® C300 to a value lower  
than the actual WFS.  
Remember: The dialed in SPD value at the Power  
Wave® C300 does not control the WFS at the  
spool gun. Rather, it is adjusting the Power  
Wave® C300 synergic work point. Therefore,  
adjusting the SPD value will not change your actu-  
al WFS at the spool gun. WFS can only be  
changed at the spool gun.  
PuSh / PuLL OPERATION  
• Set the idle roll pressure on the wire drive between  
an indicator reading of 0-2. A recommended start  
point is 1.5.  
• Configure the machine for push/pull operation (see  
parameter P.17 in the Set-up Menu section).  
• Depending on the weld mode, set the Voltage or  
Trim at the Power Wave® C300 using the right con-  
trol knob located on the upper case front panel.  
• The Wire Feed Speed (WFS) is set using the control  
knob on the Torch. The left control knob on the  
Power Wave® C300 is inactive. The actual WFS  
being set at the torch is displayed on the Power  
Wave® C300.  
• All weld parameters normally available for the active  
weld mode are available during push-pull operation.

Procedure Change Method  
Selects how remote procedure selection (A/B) will be made. The selected procedure can be  
changed locally at the user interface by pressing the 'A-Gun-B' button. The following methods  
can be used to remotely change the selected procedure:  
• Use an external switch wired to the procedure select input.  
• Quickly releasing and re-pulling the gun trigger.  
• Using a dual-schedule gun which incorporates a procedure select switch in the trigger mecha-  
nism (pulling the trigger more than half way changes the procedure from A to B).  
The possible values for this parameter are:  
• External Switch = Procedure selection may only be performed at the memory panel or an  
external switch (e.g. K683).  
• Quick Trigger = The selected procedure can be changed remotely by releasing and re-pulling  
the trigger quickly while welding. This feature is disabled in 4-Step trigger mode. The external  
procedure switch is disabled. To operate:  
1. Select "GUN" on the memory panel.  
2. Start the weld by pulling the gun trigger. The system will weld with procedure A settings.  
3. While welding, quickly release then pull the gun trigger once. The system will switch to  
procedure B settings. Repeat to switch back to procedure A settings. The procedure can  
be changed as many times as needed during the weld.  
4. Release the trigger to stop welding. The system will automatically return to procedure A  
settings.  
• Integral TrigProc = When using a Magnum DS dual-schedule gun (or similar) that incorpo-  
rates a procedure switch in the gun trigger mechanism. While welding in 2-step, machine  
operation is identical to the "External Switch" selection. When welding in 4-step, additional  
logic prevents procedure A from being re-selected when the trigger is released at step 2 of the  
4-step weld sequence. The machine will always operate in 2-step if a weld is made exclusive-  
ly in procedure A, regardless of the 2/4 step switch position (this is intended to simplify tack  
welding when using a dual-schedule gun in 4-step).  
P.6  
Stall Factor Adjustment  
This option allows the adjustment of the stall factor in Push/Pull operation. The stall factor con-  
trols the stall torque of the push motor when using a push-pull gun. The wire feeder is factory-  
set to not stall unless there is a large resistance to feeding wire. The stall factor can be reduced  
to stall more easily and possibly prevent bird nesting. However, low stall factors can cause  
motor stalling during normal welding conditions, which results in the wire burning back to the tip  
or rapid tack welds. If you are experiencing bird nests, check for other feeding problems before  
adjusting the stall factor. The default value for the stall factor is 75, with a range of 5 to 100.

Gun Offset Adjustment  
This option adjusts the wire feed speed calibration of the pull motor of a push-pull gun. This  
should only be performed when other possible corrections do not solve any push-pull feeding  
problems. An rpm meter is required to perform the pull gun motor offset calibration. To perform  
the calibration procedure do the following:  
1. Release the pressure arm on both the pull and push wire drives.  
2. Set the wire feed speed to 200 ipm.  
3. Remove wire from the pull wire drive.  
4. Hold an rpm meter to the drive roll in the pull gun.  
5. Pull the trigger on the push-pull gun.  
6. Measure the rpm of the pull motor. The rpm should be between 115 and 125 rpm. If neces-  
sary, decrease the calibration setting to slow the pull motor, or increase the calibration set-  
ting to speed up the motor.  
The calibration range is -30 to +30, with 0 as the default value.  
P.8  
TIG Gas Control  
This option allows control over which gas solenoid actuates while TIG welding.  
"Valve (manual)" = No solenoid will actuate while TIG welding, gas flow is manually controlled  
by an external valve.  
"Solenoid (auto) = The TIG solenoid will turn on and off automatically while TIG welding.  
Notes: Preflow is not available while TIG welding. Postflow is available - the same postflow  
time will be used in MIG and TIG. When machine output on/off is controlled via the upper right  
knob, gas flow will not start until the tungsten touches the work. Gas flow will continue when the  
arc is broken until the Postflow time expires. When machine output on/off is controlled via an  
arc start switch or foot Amptrol, gas will begin flowing when the output is turned on and will con-  
tinue flowing until the output is turned off and the Postflow time expires.  
P.9  
Crater Delay  
This option is used to skip the Crater sequence when making short tack welds. If the trigger is  
released before the timer expires, Crater will be bypassed and the weld will end. If the trigger is

Push-Pull Gun Knob behavior  
This option determines how the potentiometer on the Push/Pull torch will behave. Gun Pot  
Enabled = The welding wire feed speed is always controlled by the potentiometer on the push-  
pull gun (default). The left front panel knob is only used to adjust Start and Crater wire feed  
speed. Gun Pot Disabled = The wire feed speed is always controlled by the left front panel  
knob. This setting is useful when the operator wishes to have wire feed speed settings recalled  
from memories and not have the potentiometer "overwrite" the setting. Gun Pot Proc A = When  
in procedure A, the welding wire feed speed is controlled by the potentiometer on the push-pull  
gun. When in procedure B, the welding wire feed speed is controlled by the left front panel  
knob. This setting allows a fixed wire feed speed to be selected in procedure.  
P.17  
Remote Control Type  
This setup parameter was previously named "Spool/Push-Pull".  
This option selects the type of analog remote control being used. Digital remote control  
devices (those with a digital display) are configured automatically. Not all P.17 selections will  
be available on all machines. When P.17 is used to configure the remote control to function in a  
specific process, the remote will be ignored in other processes. For example, if P.17 = TIG  
Amp Control, the remote control will only function when TIG welding - the remote will be  
ignored in other processes (MIG, stick and gouge).  
Spool Gun = Use this setting while MIG welding with a spool gun that uses a potentiometer  
used for wire feed speed control (this setting is backward compatible with "P.17 Gun Selection"  
= Standard/Spool).  
Push-Pull Gun = Use this setting wile MIG welding with a push-pull gun that uses a potentiome-  
ter for wire feed speed control (this setting is backward compatible with "P.17 Gun Selection" =  
PushPull).  
TIG Amp Control = Use this setting while TIG welding with a foot or hand current control device  
(Amptrol). While TIG welding, the upper left knob on the User Interface sets the maximum cur-  
rent obtained when the TIG amp control is at its maximum setting.  
Stick/Gouge Rem. = Use this setting while stick welding or gouging with a remote output control  
device. While stick welding, the upper left knob on the User Interface sets the maximum current  
obtained when the stick remote is at it’s maximum setting. While gouging, the upper left knob  
is disabled and the gouging current is set on the remote control.  
All Mode Remote = This setting allows the remote control to function in all weld modes which is  
how most machines with 6-pin and 7-pin remote control connections operate. This setting was  
provided so that customers with a mix of Lincoln Electric equipment can have consistent  
remote control behavior across all of their equipment. (N. American default)  
Joystick MIG Gun = Use this setting while MIG welding with a push MIG gun with a joystick  
control. Stick, TIG and gouge welding currents are set at the User Interface. (European  
default)

while welding in Stick, TIG or Gouge. To prevent nuisance errors, set Arc Start/Loss Error Time  
to an appropriate value after considering all welding parameters (run-in wire feed speed, weld  
wire feed speed, electrical stick out, etc). To prevent subsequent changes to Arc Start/Loss  
Error Time, the setup menu should be locked out by setting Preference Lock = Yes using the  
Power Wave Manager software.

MAINTENANCE  
SAFETY PRECAuTIONS  
WARNING  
ELECTRIC ShOCK can kill.  
• Do not operate with covers  
removed.  
• Turn off power source before  
installing or servicing.  
• Do not touch electrically hot  
parts.  
• Turn the input power to the welding power  
source off at the fuse box before working in the  
terminal strip.  
• Only qualified personnel should install, use or  
service this equipment.  
------------------------------------------------------------------------  
ROuTINE MAINTENANCE  
Routine maintenance consists of periodically blowing  
out the machine, using a low-pressure air stream, to  
remove accumulated dust and dirt from the intake and  
outlet louvers, and the cooling channels in the  
machine.  
PERIODIC MAINTENANCE  
Calibration of the Power Wave® C300 is critical to its  
operation. Generally speaking the calibration will not  
need adjustment. However, neglected or improperly  
calibrated machines may not yield satisfactory weld  
performance. To ensure optimal performance, the cal-  
ibration of output Voltage and Current should be  
checked yearly.  
CALIbRATION SPECIFICATION  
Output Voltage and Current are calibrated at the fac-  
tory. Generally the machine calibration will not need  
adjustment. However, if the weld performance  
changes, or the yearly calibration check reveals a  
problem, use the calibration section of the  
Diagnostics utility to make the appropriate adjust-  
ments.  
The calibration procedure itself requires the use of a  
grid, and certified actual meters for voltage and cur-  
rent. The accuracy of the calibration will be directly  
affected by the accuracy of the measuring equipment  
you use. The Diagnostics utility includes detailed  
instructions, and is available on the Service  
Navigator CD or at www.powerwavesoftware.com.

TROubLEShOOTING  
There is an audible beeper associated with this input control  
board’s status light. So the error codes on the input board  
can be detected through either the status light or the status  
beeper.  
uSING ThE STATuS LED TO  
TROubLEShOOT SYSTEM PRObLEMS  
Not all of the Power Wave C300 errors will be displayed on  
the user interface. There are three status lights that contain  
error sequences that may not show up on the user interface.  
If a problem occurs it is important to note the condition of  
the status lights. Therefore, prior to cycling power to the sys-  
tem, check the power source status light for error  
sequences as noted below.  
Included in this section is information about the Status  
Lights and some basic troubleshooting charts for both  
machine and weld performance.  
The status lights on the main control board and the wire  
drive module are dual-color LED’s. Normal operation for  
each is steady green. Where as the status light on the input  
control board is one color. Normal operation is for the status  
light to be off ( and the buzzer to be off).  
There are two externally mounted status lights located  
above the wire drive in the wire feeder compartment. One of  
the status lights is for the main control board ( labeled “sta-  
tus”, and one for the wire drive module. The third status light  
is internal and is located on the input control board and can  
be seen by looking through the left case side louvers.  
Error conditions are indicated in the following Table E.1.
