OPERATING MANUAL

NOTE: FOR TIG WELDING WE RECOMMEND USING AN ARGON FLOWMETER

6.

Tighten securely with wrench.

5.

Place argon flowmeter regulator into your gas outlet.

7.

Connect gas hose to the flowmeter outlet using the
twist nut to tighten the fitting securely.

8.

Connect the other end of the gas hose to the gas inlet
on the back of the machine.
