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.
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).

Install shielding gas
MIG welding requires an appropriate bottle of shielding
gas. For mild steel either a cylinder bottle of Ar/CO
100% CO can be used refer to the following instructions

•
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.
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

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.
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
regulator adapter is required. Purchase separately
S19298b CO
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.

1. For CO
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
or
2
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.
