How to MIG Weld With a Spool Gun

Now that he's set up the aluminum spool gun on his Longevity MigWeld 140 MIG Welder, Kevin is ready to make some sparks! He turns on the welder, setting the voltage set at 7.5 and the wire feed at 70. He's prepared some 1/8" aluminum square box tubing he's been using for a sculpture by champfering the edges. Then he clamps them in a vise and uses his dedicated stainless brush to clean the aluminum before welding. Next he tack welds the aluminum on one end and runs a bead from the other. He cleans it up with the brush and assesses the weld, then flips over the scrap aluminum to run another bead. He brushes it, tacks it and runs his second bead. He brushes it one more time to admire the weld. It's that easy!
