So how does one purge without feeding wire? I really don't want to have to unload the wire from the gun every time I start up the welder just to purge the line. My welder doesn't allow for purging without feeding the wire.

Question #2. How do you know you're getting gas out the gun nozzle? When I briefly tried the gas shielded wire last fall, my welds looked like they were not getting gas because there was a lot of porosity. The gauges showed that I had gas pressure and I had the flow set for about 20cf per hour.

Thanks,
