Idealarc®250

PHASE

250 Amp DC Stick Welding Power Source

The Idealarc®250 is the classic workhorse of the Lincoln Electric stick welding power source line. It produces up to 300 amps of brute AC welding strength or down to 40 amps of smooth DC welding performance.

Add the optional TIG Module to create a versatile AC/DC TIG welder for welding aluminum or other alloy metals.

The Idealarc maintenance and repair shops where welding versatility is needed, and for the

hop or farm where ruggedness and durability is required.
