MULTIPROCESS WIRE FEEDER WELDER

GUn anD cable installation

The Magnum PRO 100L gun and cable provided with the welding
machine is factory installed with a liner for .025-.035"
(0.6-0.9mm) wire and an .035" (0.9mm) contact tip. The user
should ensure that the contact tip, liner, and drive rolls match the

configuration.
Turn the welder power switch "off" before installing gun and
cable.
1. Lay the cable straight.
2. Unscrew the hand screw which is threading into the gun
adapter.
3. Insert the male end of the gun into the female end of the gun
adapter through the opening in the front panel. Ensure the
connector is fully inserted. Then tighten the hand screw.
4. Connect the gun trigger connector from the gun and cable to
the mating receptacle located on the machine case front.

sHielDinG Gas (For MiG arc WelDinG
processes)
Customer must provide cylinder of appropriate type shielding gas
for the process being used.
A gas flow regulator, for Argon Blend gas, and an inlet gas hose
are factory provided with the welding machine. When using 100%
CO an additional adapter will be required to connect the regulator
2
to the gas bottle. Aluminum welding with a spool gun requires
WARNING
100% Argon shielding gas.
CYLINDER may explode if damaged.
Keep cylinder upright and chained to
support
• Keep cylinder away from areas where it
may be damaged.
• Never lift welder with cylinder attached.
• Never allow welding electrode to touch cylinder.
• Keep cylinder away from welding or other live electrical
circuits.
Install Shielding gas supply as follows:
1. Set the gas cylinder on a flat surface and secure the cylinder
to a sturdy structure to prevent the cylinder from falling over.
2. Remove the cylinder cap. Inspect the cylinder valves and
regulator for damaged threads, dirt , dust, oil, or grease.
Remove dust and dirt with a clean cloth.
DO NOT ATTACH THE REGULATOR IF OIL, GREASE, OR DAMAGE IS
PRESENT! Inform your gas supplier of this condition. Oil or
WARNING
grease in the presence of high pressure oxygen is explosive.
BE SURE TO KEEP YOUR FACE AWAY
FROM THE VALVE OUTLET WHEN
"CRACKING" THE VALVE.
Never stand directly in front of or behind the flow regulator
when opening the cylinder valve. Always stand to one side.
The user should distance his or her body from the valve outlet
when "cracking" the valve.
3. Stand to one side away from the outlet and open the cylinder
valve for an instant. This will eradicate any dust or dirt which
may have accumulated in the valve outlet.
4. Attach the flow regulator to the cylinder valve and tighten the
union nut(s) securely with a wrench.
NOTE: If connecting to 100% CO
adapter must be installed between the regulator and cylinder
valve. If adapter is equipped with a plastic washer, be sure it
is seated for connection to the CO
5. Attach one end of the inlet gas hose to the outlet fitting of the
flow regulator, the other end to the welding machine's rear
fitting, and tighten the union nuts with a wrench.
