My welder doesn't allow for purging without feeding the wire.

Thanks,

Sure it does Ed. Just flip down the spring loaded tension knob on your wire feed rollers, and let the upper roller pop up. Just as if you were going to load a new spool of wire. Leave the wire in the gun - just leave the top roller loose.

Open the valve on your tank, set the regulator, and turn on the welder. Now when you pull the trigger the gas should flow, but the wire won't feed because it's not being squeezed by the rollers. At this point you should be able to hear the gas flowing out the the gun nozzle.

If it sounds like the gas is flowing - turn off the machine, and then flip the tension knob back up to secure the upper roller and provide wire feed again. You are ready to weld!

Actually if my machine has been sitting a long time without being used, I will purge the gun for 5 -6 seconds just to make sure I blow out any air that has worked it's way into the hose. I also adjust the flow rate while I am purging the line and the gas is flowing. But that's just the way I roll. (lol)
