SAFETY
ARC RAYS can burn.
ELECTRIC SHOCK can 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.a. Use a shield with the proper filter and cover
plates to protect your eyes from sparks and
the rays of the arc when welding or observing
open arc welding. Headshield and filter lens
should conform to ANSI Z87. I standards.
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

your head out of the fume. Use enough
ventilation and/or exhaust at the arc to keep
3.c. In semiautomatic or automatic wire welding, the electrode,
electrode reel, welding head, nozzle or semiautomatic
welding gun are also electrically “hot”.
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.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 specific
welding procedure and application involved. Worker expo-
sure level should be checked upon installation and periodi-
cally 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 manufacturerʼs instructions for this
equipment and the consumables to be used, including the
material safety data sheet (MSDS) and follow your
employerʼs safety practices. MSDS forms are available from
your welding distributor or from the manufacturer.
5.f. Also see item 1.b.

SAFETY
WELDING and CUTTING
CYLINDER may explode
if damaged.
SPARKS can
cause fire or explosion.
6.a. Remove fire hazards from the welding area.
If this is not possible, cover them to prevent
the welding sparks from starting a fire.
7.a. Use only compressed gas cylinders
containing the correct shielding gas for the
process used and properly operating
regulators designed for the gas and

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 circuits.
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 manufacturerʼs
recommendations.
8.c. Ground the equipment in accordance with the U.S. National
Electrical Code and the manufacturerʼs recommendations.
6.h. Also see item 1.c.
6.I. Read and follow NFPA 51B “ Standard for Fire Prevention
During Welding, Cutting and Other Hot Work”, available from
NFPA, 1 Batterymarch Park,PO box 9101, Quincy, Ma
022690-9101.

SAFETY
5. Toujours porter des lunettes de sécurité dans la zone de
soudage. Utiliser des lunettes avec écrans lateraux dans les
zones où lʼon pique le laitier.
PRÉCAUTIONS DE SÛRETÉ
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 dʼincendie 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 dʼincendie.
Sûreté Pour Soudage A LʼArc
1. Protegez-vous contre la secousse électrique:
a. Les circuits à lʼélectrode 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 sʼisoler de la masse quand on
soude dans des endroits humides, ou sur un plancher met-
allique 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 defonc-
tionnement.
d.Ne jamais plonger le porte-électrode dans lʼeau pour le
refroidir.
e. Ne jamais toucher simultanément les parties sous tension
des porte-électrodes connectés à deux machines à soud-
er 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 sʼapplicuent aussi au pistolet de
soudage.
8. Sʼassurer que la masse est connectée le plus prés possible de
la zone de travail quʼil est pratique de le faire. Si on place la
masse sur la charpente de la construction ou dʼautres endroits
éloignés de la zone de travail, on augmente le risque de voir
passer le courant de soudage par les chaines de levage,
câbles de grue, ou autres circuits. Cela peut provoquer des
risques dʼincendie ou dʼechauffement des chaines et des
câbles jusquʼà ce quʼils se rompent.
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
dʼopérations de dégraissage, nettoyage ou pistolage. La
chaleur ou les rayons de lʼarc peuvent réagir avec les vapeurs
du solvant pour produire du phosgéne (gas fortement toxique)
ou autres produits irritants.
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 nʼimporte quelle partie
du corps.
PRÉCAUTIONS DE SÛRETÉ POUR
LES MACHINES À SOUDER À
TRANSFORMATEUR ET À
REDRESSEUR
3. Un coup dʼarc peut être plus sévère quʼun coup de soliel,
donc:
a. Utiliser un bon masque avec un verre filtrant approprié
ainsi quʼun verre blanc afin de se protéger les yeux du ray-
onnement de lʼarc et des projections quand on soude ou
quand on regarde lʼarc.
b. Porter des vêtements convenables afin de protéger la
peau de soudeur et des aides contre le rayonnement de
lʻarc.
c. Protéger lʼautre personnel travaillant à proximité au
soudage à lʼaide dʼécrans appropriés et non-inflammables.
1. Relier à la terre le chassis du poste conformement au code de
lʼélectricité 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, Iʼinstallation et lʼentretien du poste seront
effectués par un électricien qualifié.
3. Avant de faires des travaux à lʼinterieur de poste, la debranch-
er à lʼinterrupteur à la boite de fusibles.
4. Des gouttes de laitier en fusion sont émises de lʼarc de
soudage. Se protéger avec des vêtements de protection libres
de lʼhuile, 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.

any feeder equipped with a European style gun con-
nector or Lincoln or competative wire feeder equipped
with the proper K489 Fast-Mate Adapter Kit. See the
Parts Section “Chart E” for information on which Fast-
Mate Adapter Kit to use with various equipment.
The K478 and K479 Magnum® FM guns are factory
installed with a Fast-Mate (European style) wire feeder
connector for “all-in-one” GMAW feeder connection. A
single connector attaches welding current, wire liner,
shielding gas, and trigger control leads to the feeder.
Optional Magnum® Fast-Mate Adapters allow the use
of these guns with Lincoln and competative wire feed-
ers. See the Parts Section “Chart E” for information
on which Fast-Mate Adapter Kit to use with various
equipment.
1) Check that the feeder outgoing guide, as well as the
drive roll, are appropriate for the electrode size
being used. When using a Fast-Mate Adapter Kit,
be certain the adapter guide tube is also properly
sized.
NOTE: These guns are shipped with factory installed
liner. To change the liner in these models, see the sec-
tion on liner removal instructions in the Maintenance
section.
2) Align and fully engage the brass connector end of
the gun cable into the mating connector on the out-
going side of the feeder wire drive. Secure the cable
connection by snugging the Fast-Mate connector

CABLE REPAIR
NOTE: For best results, insert a rod through the
connector and into the core of the cable approxi-
mately 5.00” (127 mm) when pushing the connector
tube into the cable core tube. A .219”/.240” (5.6-6.1
mm) diameter rod is required for 300 and 400 amp
cables. To tighten, hold the connector in place while
turning the nut, then remove the rod from the core.
This procedure assures the inner core does not kink
while assembling or tightening.
The Magnum® 300 FM and Magnum® 400 FM guns
feature the use of repairable cable connectors. If the
cable ever gets severely damaged, it may be cut short-
er and repaired by the user. Repair cables as follows:
Gun Tube End Repair (K478 and K479) (Requires 2
#S19492-2 Terminals)
a) Remove the cable liner per “Removal Instructions
for Magnum® Liners”.
h) Pull the cut-off lead terminals off the trigger assem-
bly and connect the replacement control lead termi-
nals.
b) Remove the gun tube per “Gun Tubes and
Nozzles“.
j) Position the cable boot and the strain relief on the
cable so it fits in the cable handle cavity and lock
the strain relief in place by pushing the two halves
together.
c) Remove three #6 screws from the gun handle, sep-
arate the two halves, and remove the cable from the
handle along with the trigger assembly.
k) Assemble the cable in the left side of the gun han-
dle. Assemble the trigger into the proper handle
cavity. Assemble the right side of the gun handle
and tighten the three screws that hold the handle
together. Refer to Figure E.4.
d) Remove the gun tube connector from the cable by
unscrewing the connector nut from the gun tube
connector. If the cable inner tube is difficult to
remove from the connector assembly, carefully slit it
lengthwise with a knife up to the brass connector.
l) Install the gun tube per “Gun Tubes and Nozzles“.
e) Uncouple the strain relief by pushing its outer hous-
ing toward the middle of the cable. Move the strain
relief and the cable boot toward the middle of the
cable, past the damaged section.
m) Install and trim the liner per “Liner Installation and
Trimming Instructions”.
f) Cut off the damaged section of the cable and strip
off the outer jacket as shown in Figure E.2. Be care-
ful not to cut the insulation on the control wires while
stripping the jacket. Strip the red and white control
leads 1/4 inch (6.4 mm) from the end and crimp a
new S19492-2 terminal to each lead.
Wire Feeder End Repair (K478 and K479 FM Models
Only)
a) Remove the cable liner per “Removal, Installation
and Trimming Instructions for Magnum® Liners”.
NOTE: The cable contains three control leads. Any
two control leads can be used, provided the two col-
ors used are the same at both ends. The extra lead
is a spare that can be used if one of the other leads
breaks.
b) Loosen the boot nut. Slide the boot nut and boot
toward the middle of the cable past the damaged
section.
g) Check that the cable boot and both halves of the
strain relief are on the cable. Slip the connector nut
over the copper strands with the thread end out.
Orient the gun tube connector so the machined flat
is on the same side of the cable as the red and
white control leads. Assemble the gun tube connec-
tor to the cable by forcing the steel tube of the con-
nector into the inside diameter of the cable inner
tube until the copper strands are butted against the
gun tube connector shoulder. Keeping the copper
strands against the shoulder, pull the connector nut
over the copper strands, engage the gun tube con-
nector threads, and tighten in place. Refer to Figure
E.3.
c) Rotate the collar nut until the screw anchoring the
cable handle is visible. Remove the screw and save
it.
d) Slide the cable handle, collar nut and strain relief
housing toward the middle of the cable past the
damaged section. On older cables remove and
save the cable clamp that was used in place of the
strain relief.
NOTE: If sliding the cable handle becomes difficult,
try rotating it 180°.

e) Remove the incoming connector from the cable by
unscrewing the connector nut from the incoming
connector. If the cable inner tube is difficult to
remove from the connector assembly, carefully slit it
lengthwise with a knife up to the brass connector.
NOTE: For best results, insert a rod through the
connector and into the core of the cable approxi-
mately 5.00” (127 mm) when pushing the connector
tube into the cable core tube. A .219”/.240” (5.6-6.1
mm) diameter rod is required for 300 and 400 amp
cables. To tighten, hold the connector in place while
turning the nut, then remove the rod from the core.
This procedure assures the inner core does not kink
while assembling or tightening.
f) Cut the cable control wires where they meet the
cable jacket or else unsolder the connection where
they connect to the terminal lead assembly. If you
cut the wires, strip the cut end 3/8 inch (9.5 mm)
from the end.
j) Solder the terminal lead assemblies from step (f) to
the control leads stripped in step (g). Insulate both
soldered connections using either heat shrink tub-
ing or electrical tape.
g) Cut off the damaged section of cable and strip off
the outer jacket as shown in Figure E.2. Be careful
not to cut the insulation on the control wires while
stripping the jacket. Strip the red and white control
leads 3/8 inch (9.5 mm) from the end.
k) Fully insert the two control lead pins into the sock-
ets on the incoming connector. Tape the leads in
place in the necked down area of the connector.
Keeping the leads as close to the connector and nut
as possible, tape the insulated, soldered connec-
tions and the spare lead to the cable in the area
between the cable jacket and connector nut. This
must be done neatly and kept as low as possible or
the cable handle will not slide over this area.
NOTE: The cable contains three control leads. Any
two control leads can be used, provided the two col-
ors used are the same at both ends. The extra lead
is a spare that can be used if one of the other leads
breaks.
h) Check that the cable boot, boot nut, cable handle,
strain relief housing and collar nut are on the cable.
Slip the connector nut over the copper strands with
the threaded end out. Orient the connector assem-
bly so the red and white control leads will have the
straightest possible routings to the sockets on the
back side of the connector. Assemble the incoming
connector to the cable by forcing the steel tube of
the connector into the inside diameter of the cable
inner tube until the copper strands are butted
against the incoming connector shoulder. Keeping
the copper strands against the shoulder, pull the
connector nut over the copper strands, engage the
incoming connector threads, and tighten in place.
Refer to Figure E.3.
l) Position the strain relief to the dimension shown in
Figure E.5 and secure with the strain relief housing.
On older cables install the cable clamp on the cable
jacket within 1/8” (3.2 mm) from the end of the jack-
et and tighten.
m) Slide the collar nut and cable handle over the con-
nection and into place. Anchor the cable handle with
the screw removed in step (c). Slide the boot and
boot nut into place and tighten.
NOTE: If the cable handle becomes difficult to slide
over connection, try rotating it.
