SG-2 Spool Gun

With its short feed distance, a spool gun provides a steady, reliable feed of the soft aluminum wire. A smooth feed to the weld is key to getting that smooth arc. As an alternative to a spool gun, it may be possible for you to adjust or adapt your MIG welder so that it can provide a steady, reliable feed of wire to the weld.

Most economical and reliable spool gun in its class! Designed specifically for home hobbyists & light fabricators. Rated at 160 amps at 60% duty cycle - ideal for welding with .023 - .035 wires.

Besides the high cost, there are other disadvantages to using a spool gun. Spool guns are heavy and bulky, so they’re not ideal for the faster travel speed needed for aluminum welding, or use in tight quarters. Also, capacity is limited to small, one-pound spools.
