Gas MIG Welding Setup
NOTE:
Gas MIG welding will require a gas cylinder. (Argon mix or CO2)
1.
Connect the gas regulator to a gas cylinder (not included with machine) and connect the gas hose
from the regulator to the gas inlet connection on the rear of the machine. Ensure all hose
connections are tight and clamped with the hose clamps provided.
2.
Open gas cylinder valve and adjust regulator. Pull the trigger on the MIG torch to initiate flow of
gas through the welding torch. Flow should be between 10-25L/min depending on application.
