The Century AC-120 Stick Welder has a 50 to 90 amp output that supports mild steel stick electrode diameters from 1/16" to 5/64". The smooth arc provides strong welds on up to 14 gauge steel. It has a 20% duty cycle at 55 amps that allows it to run 2 minutes out of each 10-minute period without overheating. Built-in thermal overload protection provides extended life. The welder comes with a work cable with electrode holder and an input cable with attached three-prong plug.SpecificationsWelding output50-90 ampDuty cycle20% at 55 ampInput power120V, 60 Hz, 1 phaseDimensions11" H x 7" W x 11" DWeight24.5 lb.*H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back. Welders join two or more pieces of metal to form one solid piece by simultaneously applying heat to soften them and applying pressure to connect them. Stick welders, also known as arc welders, use an electrified arc that flows between a welding stick and the metal to join the pieces. Wire-fed welders use an electrified wire spool that is fed at a constant speed between the pieces of metal to join them.Lincoln Electric manufactures welders and welding supplies, including the Century brand. The company, founded in 1895, is headquartered in Cleveland, OH.What"s in the Box?(1) Century AC-120 Stick Welder(1) work cable and electrode holder assembly(1) input cable with attached plug
