Spot Weld Gun produces spot welds very similar to those made when your car was built. Joins panels without the need to grind off weld beads. Spot welding is fast, avoids distortion and confines heat. Stitch Welder makes arc welding sheet metal easy. A reduction diode lets you use AC arc welders that can be set to 80 amps or less. The diode reduces output by half, so sheet metal as thin as 22 gauge can be safely welded. All circuits have a 100% duty cycle. The arc is self-starting so there is less chance of the rod sticking.
