Kevin sets up his Longevity MigWeld 140 MIG welder with a spool gun so he can weld with aluminum. He opens the machine, removes the welding wire that was in the machine to save it, removes the MIG welding gun and control cable from the front of the machine. He then attaches the spool gun by attachng the power lead and tightening the wing nut. He then flips the switch to enable the spool gun, and hooks up the control cable. He also shows the inside of the spool gun, which comes with a spool of aluminum wire. He shows the tension nut that holds the spool of wire on, the tension knob for the roller for the wire feed, and the other end of the nozzle where it goes out to the gun. Kevin also talks about using the spool gun for other kinds of welding. Next up is welding with the spool gun – stand by for the next video.
