Lincoln Electric AC-225 - Manual

Recommended General Options
Wheel Kit, Carbon Arc Welding Torch
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.
