4.4 Back Panel/Gas Connector
When using the MIG (GMAW) welding process (solid wire) a shielding gas is required. Familiarize yourself with the location of the “Back Panel” tapered nozzle Gas Connector before attempting to operate.
A stainless steel hose clamp is recommended to ensure a leak-proof connection.
Using a secured GMAW shielding gas cylinder, slowly crack open then close the cylinder valve while standing off to the side of the valve. This will remove any debris that may be around the valve & regulator seat area.
Install the regulator and tighten with a wrench.
Connect the gas hose to the outlet of the regulator, and tighten with a wrench.
Connect the other end of the gas hose to the “Gas Connector” on the rear panel of the welder. (See image on previous page) A stainless steel hose clamp is recommended to ensure a leak-proof connection.
Be sure the gas valve on the torch is closed, and slowly open the cylinder valve to the fully open position.
Connect the ground clamp to your work piece.
Plug the power cable into the appropriate outlet, and turn the switch to the “ON” position. The power L.E.D. light should illuminate.
Set the “Adjustment Switched” to the desired voltage.
You are now ready to begin MIG Welding
