21. Based on the thickness of the material you are
going to weld and the type and diameter of the
welding wire set the voltage and the wire feed
speed per the procedure decal attached to the
inside of the wire drive compartment door.
WARNING
MOVING PARTS AND ELECTRICAL CONTACT CAN
CAUSE INJURY OR BE FATAL.
•
When the gun trigger is depressed drive rolls, spool
of wire and electrode are ELECTRICALLY LIVE
(HOT).
•
Keep away from moving parts and pinch points.
•
Keep all doors, covers, panels and guards securely
in place.
DO NOT REMOVE OR CONCEAL WARNING LABELS.

guide
3. 0.6mmDrive
Roll
4. 0.6mm SuperArc L-56 Solid MIG Wire
5. Brass gun nozzle
6. Welding

7. Work Cable & Clamp
8. Gas Regulator & Gas Line
9. Bottle of 75/25 Ar/CO
2
shielding gas (or 100% CO
2
shielding gas) (note this requires a CO
2
regulator
adapter which is sold separately).
Install shielding gas
MIG welding requires an appropriate bottle of shielding
gas. For mild steel either a cylinder bottle of Ar/CO
2
or
100% CO
2
can be used refer to the following instructions
to properly connect shielding gas to the machine.
WARNING
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.
WARNING
BUILDUP OF SHIELDING GAS may harm health or kill.
•
Shut off shielding gas supply when not in use.
1. Secure the cylinder to a wall or other stationary
support to prevent the cylinder from falling over.
Insulate the cylinder from the work circuit and earth
ground
.
2. With the cylinder securely installed, remove the
cylinder cap. Stand to one side away from the
outlet and open the cylinder valve very slightly for
an instant. This blows away any dust or dirt which
may have accumulated in the valve outlet.
WARNING
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.
3. Attach the flow regulator to the cylinder valve and
tighten the union nut securely with a wrench.
NOTE:
If connecting to 100% CO
2
cylinder, a CO
2
regulator adapter is required. Purchase separately
S19298b CO
2
adapter be sure to install plastic
washer included in the fitting on the bottle side. (See
the Figure above.)
4. Refer to Figure above. Attach one end of inlet gas
hose to the outlet fitting of the flow regulator and
tighten the union nut securely with a wrench.
Connect the other end to the machine Solenoid Inlet
Fitting (5/8-18 female threads - for CGA - 032
fitting). Make certain the gas hose is not kinked or
twisted.
Shielding Gas
1. For
CO
2
, open the cylinder very slowly. For argon-
mixed gas, open cylinder valve slowly a fraction of a
turn. When the cylinder pressure gauge pointer
stops moving, open the valve fully.
2. Set gas flow rate for 30 to 40 cubic feet per hour (14
to 18 I/min.) under normal conditions, increase to as
high as 40 to 50 CFH (18 to 23.5 I/min.) under drafty
(slightly windy) conditions.
3. Keep the cylinder valve closed, except when using
the machine.
