SHIELDING GAS

[For Gas Metal Arc Welding(GMAW) Processes]
Customer must provide cylinder of appropriate type shielding gas
for the process being used.
A gas flow regulator, for Argon blend gas, an inlet gas hose, and a
regulator adapter are factory provided with the POWER MIG
When using 100% CO , the regulator adapter will be required to
2
connect the regulator to the gas bottle.
WARNING
CYLINDER may explode if
• Gas under pressure is explosive. Always
keep gas cylinders in an upright position
and always keep chained to undercarriage
or stationary support.
See American National Standard Z49.1, "Safety in Welding
and Cutting" published by the American Welding Society.
Install shielding gas supply as follows:
1. Set gas cylinder on rear platform of POWER MIG
chain in place to secure cylinder to rear of welder.
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 grease in the presence of high pressure
oxygen is explosive.
3. Stand to one side away from the outlet and open the cylinder
valve 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.
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 provided must be installed between the regulator and
cylinder valve.
5. Attach one end of the inlet gas hose to the outlet fitting of the
flow regulator, the other end to the POWER MIG
fitting marked "Feeder" and tighten the union nuts securely
with a wrench.
6. Before opening the cylinder valve, turn the regulator adjusting
knob counterclockwise until the adjusting spring pressure is
released.
7. Standing to one side, open the cylinder valve slowly a fraction
of a turn. When the cylinder pressure gauge pointer stops
moving, open the valve fully.

WARNING
Never stand directly in front of or behind the flow regulator
when opening the cylinder valve. Always stand to one side.
8. The flow regulator is adjustable. Adjust it to the flow rate
recommended for the procedure and process being used
before making the weld.
