Kevin sets up his Longevity MigWeld 140 MIG welder to weld with .035 flux core wire without gas. Then he welds some 16 gauge steel, and some 1/8″ plate steel, adjusting the controls as he goes, explaining why and how he is adjusting them. Finally, he explains what flux core welding is and how similar it is to arc welding.

Kevin also raves about the quiet, compact 110 volt, 140 amp MIG welder, which is rated to 1/8″ plate steel and includes a spool gun for welding aluminum. Learn more about the MigWeld 140.
