I press the trigger a couple of times then cut the wire with side cutters, or if real lazy just let it burn off. While your getting smoke off the weld (assuming some oil residue) bring the nozzle close but sideways so the wire won't touch, pull the trigger and see if the gas flow moves the smoke. Try a weld with the gas turned off and compare. Your porosity could be due to poor wire. I picked up a 40 pound spool that was crap. Would weld fine then the next couple of inches of bead would boil with porosity. Checked the package, made in china, couldn't believe a reputable welding supplier would carry it. Questioned them on it and they said I was the first to complain. Next spool was domestic and fine.
