should conform to ANSI Z87. I standards.  
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  
can be dangerous.  
5.a. Welding may produce fumes and gases  
hazardous to health. Avoid breathing these

• DC Manual (Stick) Welder.  
• AC Welder with Reduced Voltage Control.  
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 below Threshold Limit Values (TLV)  
using local exhaust or mechanical ventilation. In  
confined spaces or in some circumstances, 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.  
5.b. 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 sol-  
vent vapors to form phosgene, a highly toxic gas, and other  
irritating products.  
3.f. Maintain the electrode holder, work clamp, welding cable and  
welding machine in good, safe operating condition. Replace  
damaged insulation.  
3.g. Never dip the electrode in water for cooling.  
5.c. 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.  
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.d. 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.  
3.i. When working above floor level, use a safety belt to protect  
yourself from a fall should you get a shock.

SAFETY  
WELDING SPARKS can  
cause fire or explosion.  
CYLINDER may explode  
if damaged.  
6.a. Remove fire hazards from the welding area.  
If this is not possible, cover them to prevent  
7.a. Use only compressed gas cylinders  
containing the correct shielding gas for the  
the welding sparks from starting a fire.  
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.  
process used and properly operating  
regulators designed for the gas and  
pressure used. All hoses, fittings, etc. should be suitable for  
the application and maintained in good condition.  
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.  
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.  
•A safe distance from arc welding or cutting operations and  
any other source of heat, sparks, or flame.  
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.  
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.a. Turn off input power using the disconnect  
switch at the fuse box before working on  
the equipment.  
8.b. Install equipment in accordance with the U.S. National  
Electrical Code, all local codes and the manufacturer’s  
recommendations.  
6.h. Also see item 1.c.  
8.c. Ground the equipment in accordance with the U.S. National  
Electrical Code and the manufacturer’s recommendations.

SAFETY  
zones où l’on pique le laitier.  
PRÉCAUTIONS DE SÛRETÉ  
6. Eloigner les matériaux inflammables ou les recouvrir afin de  
prévenir tout risque d’incendie dû aux étincelles.  
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:  
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:  
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.  
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.  
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.  
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.  
d.Ne jamais plonger le porte-électrode dans l’eau pour le  
refroidir.  
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.  
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.  
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.  
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.  
PRÉCAUTIONS DE SÛRETÉ POUR  
LES MACHINES À SOUDER À  
TRANSFORMATEUR ET À  
REDRESSEUR  
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.  
b. Porter des vêtements convenables afin de protéger la  
peau de soudeur et des aides contre le rayonnement de  
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.  
2. Autant que possible, I’installation et l’entretien du poste seront  
effectués par un électricien qualifié.  
c. Protéger l’autre personnel travaillant à proximité au  
soudage à l’aide d’écrans appropriés et non-inflammables.  
3. Avant de faires des travaux à l’interieur de poste, la debranch-  
er à l’interrupteur à la boite de fusibles.  
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.  
4. Garder tous les couvercles et dispositifs de sûreté à leur  
place.  
5. Toujours porter des lunettes de sécurité dans la zone de  
soudage. Utiliser des lunettes avec écrans lateraux dans les

MACHINE GROUNDING AND HIGH FRE-  
QUENCY INTERFERENCE PROTECTION  
Safety Precautions  
The Capacitor Discharge Circuit used in the high fre-  
quency generator, may cause many radio, TV and  
electronic equipment interference problems. These  
problems may be the result of radiated interference.  
Proper grounding methods can reduce or eliminate  
radiated interference.  
WARNING  
ELECTRIC SHOCK can kill.  
• Only qualified personnel should per-  
form this installation.  
The Invertec V205-T AC/DC has been field tested  
under recommended installation conditions. It com-  
plies with FCC allowable limits for radiation.  
• Turn the input power OFF and  
unplug the machine from the recep-  
tacle before working on this equip-  
ment. Allow machine to sit for 5 min-  
utes minimum to allow the power  
capacitors to discharge before  
working inside this equipment.  
Radiated interference can develop in the following  
four ways:  
1. Direct interference radiated from the welder.  
•
•
Insulate yourself from the work and ground.  
Always wear dry insulating gloves.  
• Always connect the V205-T to a power supply  
grounded according to the National Electrical  
Code and local codes.  
2. Direct interference radiated from the welding leads.  
3. Direct interference radiated from feedback into the  
power lines.  
------------------------------------------------------------  
SELECT SUITABLE LOCATION  
4. Interference from re-radiation of “pickup” by  
ungrounded metallic objects.  
The Invertec will operate in harsh environments. Even  
so, it is important that simple preventative measures  
are followed in order to assure long life and reliable  
operation.  
Keeping these contributing factors in mind, installing  
equipment per the following instructions should mini-  
mize problems.  
1. Keep the welder power supply lines as short as  
possible and enclose as much of them as possible  
in rigid metallic conduit or equivalent shielding for a  
distance of 50 feet (15.2m). There should be good  
electrical contact between this conduit and the  
welder case ground. Both ends of the conduit  
should be connected to a driven ground and the  
entire length should be continuous.  
• The machine must be located where there is free cir-  
culation of clean air such that air movement in the  
back and out the front will not be restricted.  
• Dirt and dust that can be drawn into the machine  
should be kept to a minimum. Failure to observe  
these precautions can result in excessive operating  
temperatures and nuisance shutdown.  
STACKING  
2. Keep the work and electrode leads as short as  
possible and as close together as possible.  
Lengths should not exceed 25 ft (7.6m). Tape the  
electrode and work leads together into one bundle  
when practical.  
The Invertec V205-T AC/DC can not be stacked.  
TILTING  
Place the machine directly on a secure, level surface.  
The machine may topple over if this procedure is not  
followed.  
ENVIRONMENTAL AREA  
Keep the machine dry. Do not place it on wet ground  
or in puddles.

INSTALLATION  
3. Be sure the torch and work cable rubber cover-  
ings are free of cuts and cracks that allow high  
frequency leakage. Cables with high natural rub-

Be sure the voltage, phase, and frequency of the input  
power is as specified on the rating plate, located on  
the bottom of the machine.  
®
ber content, such as Lincoln Stable-Arc better  
resist high frequency leakage than neoprene and  
other synthetic rubber insulated cables.  
4. Keep the torch in good repair and all connections  
tight to reduce high frequency leakage.  
WARNING  
5. The work terminal must be connected to a ground  
within ten feet of the welder, using one of the fol-  
lowing methods.  
ELECTRIC SHOCK can kill.  
• Have a qualified electrician install  
and service this equipment.  
• Turn the input power OFF and unplug  
the machine from the receptacle  
before working on this equipment.  
a) A metal underground water pipe in direct con-  
tact with the earth for ten feet or more.  
b) A 3/4” (19mm) galvanized pipe or a 5/8”  
(16mm) solid galvanized iron, steel or copper  
rod driven at least eight feet into the ground.  
• Allow machine to sit for 5 minutes minimum to  
allow the power capacitors to discharge before  
working inside this equipment.  
The ground should be securely made and the  
grounding cable should be as short as possible  
using cable of the same size as the work cable, or  
larger. Grounding to the building frame electrical  
conduit or a long pipe system can result in re-radi-  
ation, effectively making these members radiating  
antennas.  
• Do not touch electrically hot parts.  
• Machine must be plugged into a receptacle that  
is grounded according to the National Electrical  
Code and local codes.  
6. Keep all panels securely in place.  
• Do not remove or defeat the purpose of the  
power cord ground pin.  
7. All electrical conductors within 50 ft (15.2m) of the  
welder should be enclosed in grounded, rigid  
metallic conduit or equivalent shielding. Flexible  
metallic conduit is generally not suitable.  
-----------------------------------------------------------------------  
8. When the welder is enclosed in a metal building,  
several earth driven electrical grounds connected  
(as in 5b above) around the periphery of the build-  
ing are recommended.  
RECONNECT PROCEDURE  
The Invertec V205-T AC/DC auto reconnects to either  
115V or 230V supply.  
Fuse the input circuit with time delay fuses or delay  
type circuit breakers. Using fuses or circuit breakers  
smaller than recommended may result in “nuisance”  
shut-offs from welder inrush currents even if not weld-  
ing at high currents.  
Failure to observe these recommended installation  
procedures can cause radio or TV interference prob-  
lems.  
1
The Invertec V205-T AC/DC is recommended for use  
on an individual branch circuit.  
1Also called “inverse time” or “thermal/magnetic” circuit breakers.  
These circuit breakers have a delay in tripping action that  
decreases as the magnitude of the current increases.

INSTALLATION  
In all cases, the green or green/yellow grounding wire  
must be connected to the grounding pin of the plug, usu-  
ally identified by a green screw.  
230V INPUT  
The equipment is provided with a 230/115V cable,  
6.6ft.(2m) in length with a 230V 6-50P attachment  
plug.  
Attachment plugs must comply with the Standard for  
Attachment Plugs and Receptacles, UL498.  
The Invertec V205-T AC/DC performs best when con-  
nected to 230VAC inputs. This input allows full output  
of the machine (200 amps).  
The product is considered acceptable for use only when  
an attachment plug as specified is properly attached to  
the supply cord.  
115V INPUT  
For use on engine drives, keep in mind the above  
input draw restrictions and the following precaution.  
A suitable 115V attachment plug must be installed on the  
power cord to use the V205-T AC/DC with a 115V input  
supply. The rated output of the V205-T AC/DC is avail-  
able when connected to a 30A branch circuit. When con-  
nected to a branch circuit with lower amp rating, lower  
welding current and duty cycle must be used. An output  
guide is provided below. The values are approximate and  
must be adjusted downward if the fuse or circuit breaker  
trips off. Other loads on the circuit and fuse/circuit break-  
er characteristics will affect the available output. Do not  
exceed these welding conditions:  
ENGINE DRIVEN GENERATOR  
The Invertec V205-T AC/DC can be operated on  
engine driven generators as long as the 230 volt auxil-  
iary meets the following conditions:  
• The AC waveform peak voltage is below 400 volts.  
• The AC waveform frequency is between 45 and  
65Hz.  
The following Lincoln engine drives meet these condi-  
tions when run in the high idle mode:  
• Ranger 250,305  
15A branch circuit  
10% duty cycle  
Stick: 75A  
• Commander 300, 400, & 500  
Some engine drives do not meet these conditions  
(e.g. Miller Bobcats, etc). Operation of the Invertec  
V205-T AC/DC is not recommended on engine drives  
not conforming to these conditions. Such drives may  
deliver unacceptably high voltage levels to the  
Invertec V205-T AC/DC power source.

2-Step Sequence  
With the Trigger Mode switch in the 2-step position,  
the following welding sequence will occur. This  
sequence is shown in (2-step diagram 1)  
1. Press and hold the Arc Start Switch to start the  
sequence.  
4-Step Sequence  
With the 4-step Selected, the following welding  
sequence will occur.  
The machine will open the gas valve to start the flow  
of the shielding gas. After a 0.5 second preflow time,  
to purge air from the torch hose, the output of the  
machine is turned ON. At this time the arc is started.  
1. Press and hold the Arc Start Switch to start the  
sequence.  
The machine will open the gas valve to start the flow  
of the shielding gas. After a 0.5 second preflow time,  
to purge air from the torch hose, the output of the  
machine is turned ON. At this time the arc is started.  
After the arc is started the output current will be  
increased from the start current to the welding cur-  
rent. Both the start current and increase, or upslope  
time are presettable. The default start current is 15  
amps and the default upslope time is 0.2 seconds.  
After the arc is started the output current will be at  
the Start current. This condition can be maintained  
as long or as short as necessary.  
2. Release the Arc Start Switch to stop welding.  
The machine will now decrease the output current at  
a controlled rate, or downslope time, until the Finish  
current, (also commonly referred to as Crater  
Current) is reached and the output of the machine is  
turned OFF. Both the Downslope Time and the  
Finish Current are can be preset.  
If the Start current is not necessary, do not hold the  
TIG torch trigger as described at the beginning of  
this step. Instead, quickly press and release the trig-  
ger. In this condition, the machine will automatically  
pass from Step 1 to Step 2 when the arc is started.  
After the arc is turned OFF, the gas valve will  
remain open to continue the flow of the shielding  
gas to the hot electrode and work piece. The dura-  
tion of this postflow shielding gas is adjusted by the  
Postflow Parameter.  
2. Release the TIG torch trigger to start the main part  
of the weld.  
The output current will be increased from the start  
current to the welding current. Both the start current  
and increase, or upslope time are presettable. The  
default start current is 15 amps and the default ups-  
lope time is 0.2 seconds.

WELDING POLARITY  
OUTPUT LIMITATIONS  
DC Electrode Negative Polarity (Direct Current  
Straight Polarity)  
(see FIGURE B.4)  
While Welding, there is a continuous flow of electrons  
from the electrode to the workpiece.  
The maximum output current as specified in the instal-  
lation section of this manual is derated in two situa-  
tions; alternate AC Wave Forms and elevated AC  
Frequencies.  
• Alternate AC Wave Forms (See Set Up Menu)  
This is the most used polarity, ensuring limited wear of  
the electrode, since the majority of the heat concen-  
trates on the anode (workpiece). Narrow and deep  
welds are obtained with high travel speeds.  
Square  
200 amps max. output  
Sinusoidal 150 amps max. output  
Triangular 120 amps max output  
• Elevated AC Frequencies  
Most materials, with the exception of aluminum and  
magnesium, are welded with this polarity.  
Above 85Hz (AC output) the square wave out-  
put is limited to 170 amps. Elevated AC  
Frequencies do not effect the output of  
Sinusoidal and Triangular Waveforms.  
FIGURE B.4  
These derated values have been programmed into the  
Invertec V205-T AC/DC to ensure reliable operation.  
DC TIG WELDING  
(see FIGURE B.3)  
The TIG (Tungsten lnert Gas) welding process is  
based on the presence of an electric arc between a  
non-consumable electrode (pure or alloyed tungsten  
with an approximate melting temperature of 3370°C)  
and the workpiece. An inert gas (typically argon)  
atmosphere protects the weld pool.  
To avoid inclusions of tungsten in the joint, the elec-  
trode should not contact the workpiece. For this rea-  
son the arc is started through a Hi. Freq. generator.  
For situations requiring no Hi. Freq., Touch Start Tig  
reduces the short-circuit current to keep tungsten  
inclusions to the minimum.  
To improve weld bead quality at the end of the weld it  
is important to carefully control the downslope of cur-  
rent and ensure proper gas coverage over the weld.

Reverse Polarity) (see Figure B.5)  
A.C. (Alternating Current)  
(see Figure B.7)  
In this case, there is a continuous flow of electrons  
from the workpiece to the electrode. The reverse  
polarity is used for welding alloys covered with a layer  
of refractory oxide.  
Alternating Current welding is typically used for Tig  
welding aluminum (and its alloys) or magnesium. The  
polarity alternates between Electrode Positive and  
Electrode Negative (EN). During the positive half-  
wave the oxide is broken. During the negative half-  
wave, the electrode cools, the workpiece melts and  
penetration occurs.  
With this polarity the electrode functions as anode and  
is subjected to a high degree of heat; the workpiece is  
bombardment by positive ions sent from the electrode  
which break the surface oxide.  
FIGURE B.7  
In Electrode Positive Polarity, high currents cannot be  
used, since they would cause an excessive wear of  
the electrode.  
NOTE: (The Invertec V205-T AC/DC cannot be used  
Greater % EN = MORE PENETRATION  
Lesser % EN = more CLEANING  
50% (EN)  
for Electrode Positive TIG welding without special  
adapters.)  
FIGURE B.5  
Changing the wave balance alters the ratio between  
the cleaning and the penetrating current.  
A.C.-Pulsed TIG  
When AC welding, a pulsed current can be used, with  
similar effects to those described in pulsed direct  
current welding.  
FIGURE B.8  
D.C.-Pulsed TIG  
A.C.- PULSED TIG  
(see Figure B-6)  
The use of pulsed direct current allows better control  
of the weld pool during certain operating conditions.  
When compared with traditional TIG welding per-  
formed at the same average current, pulsed welding  
results in a smaller heat affected zone which results in  
fewer deformations and reduced chance of cracking  
and gas entrapment.  
Increasing the frequency constricts the arc, increases  
stability and improves weld quality.

OPERATION  
1. The AC wave balance can be set to a higher per-  
centage electrode negative which minimizes tung-  
sten heating and erosion.  
2. The AC frequency can be varied to "focus" the arc.  
Increasing the AC frequency above 60Hz will nar-  
row the cone shape arc from the tungsten’s tip.  
Decreasing the AC frequency below 60Hz will  
broaden the cone shape arc from the tungsten’s tip.  
STEEL TIG WELDING  
The TIG process is very effective for welding both car-  
bon steel and alloy steel, especially in applications  
requiring precision results. DC Electrode Negative  
Polarity is required. Since this process does not  
include the removal of impurities, proper cleaning and  
preparation of the edges is required.  
FILLER MATERIAL:  
The filler rods must deposit welds with mechanical  
characteristics appropriate for the application.  
The two above benefits can be used to maintain a  
tight focus of the arc for precise heat control and tight  
joint access. Because of the AC inverters abilities in  
these areas the following recommendations are made  
as a starting point:  
COPPER TIG WELDING  
Since the TIG welding is a process characterized by  
high heat concentration, it is particularly suitable for  
welding materials with high thermal conductivity, like  
copper. As with steel, the DC Electrode Negative  
Polarity is employed, with argon as protective gas.  
Considering the fluidity of molten copper, the use of  
backup support may prove useful.  
• A 2% Thoriated tungsten is recommended instead  
of the Pure tungsten that is normally recommended  
for AC welding. Thoriated tungstens emit electrons  
easier and therefore will improve starting.  
• Sharpen the tungsten to a point. Normally it is rec-  
ommended to pre-ball a pure tungsten when AC  
welding with a conventional power source.  
However, the AC inverter with it’s extended AC bal-  
ance control minimized tungsten heating thus allow-  
ing for a pointed tungsten to be used.  
FILLER MATERIAL:  
In order to avoid the oxidation of the molten material,  
filler materials containing phosphorus, silicon or other  
deoxidating materials are typically used. The mechan-  
ical properties can also be improved through the use  
of silver.  
• Set the AC Balance control to maximum 85% elec-  
trode negative. This can be reduced if the material  
welded is heavily oxidized, however starting at max-  
imum and adjusting to less is desired.  
TIPS FOR AC TIG WELDING  
AC Inverter TIG power sources offer two significant  
advantages over conventional Silicon Controlled  
Rectifier (SCR) / transformer power sources:  
• Set the AC Frequency in the 100 to 120 Hz range.  
This is a "Sweet Spot" for most aluminum applica-  
tions.

OPERATION  
PROTECTIVE GAS  
Both argon and helium work when welding aluminum.  
Argon is preferred, due to its lower cost and consump-  
tion rate. This gas also tends to stabilize the arc, thus  
making it easy to operate. For some applications,  
however, the use of helium, or argon-helium blends, is  
recommended due to better weld penetration and  
faster travel speed. Helium is especially suitable for  
welding thick workpieces. The recommended gas flow  
rates are shown in table 5.  
The Invertec V205 T AC/DC TIG is ready to AC TIG  
weld with the following features:
