STICK WELDERS

AC-225

The AC-225 compact stick welder has a broad welding amperage range of 40-225 amps. It produces an extremely smooth AC arc for welding a wide variety of materials including carbon, low alloy, and stainless steels as well as cast iron. Metals 16 gauge and heavier can be easily arc welded with the AC-225.

Applications include: repair and maintenance welding, fabricating or modifying equipment, building tools or fixtures, build-up welding on worn parts or dies, and hardfacing new or worn parts for longer service life. Also for cutting and piercing holes in steel.
