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

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

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
