The Rogue ES is a robust and durable power source for the professional welder. The machine provides state-of-the-art welding performance and reliability through use of the latest high performance power electronics and digital control; ensuring a precise consistent arc. The Rogue ES provides smooth DC (Direct Current) welding power which allows you to weld a variety of metals, such as alloyed and non alloyed steel, stainless steel, and cast iron. Featuring Arc Force and Hot Start settings for more control over your arc. Digital microprocessor offers more control over all arc parameters and provides best-in-class welding performance. The Rogue ES 201iP PRO weld electrodes up to 4.0 mm (5/32 in.) and Rogue ES 151iP PRO weld 3.2 mm (1/8 in.) electrodes. New Pulse SMAW functionality enhances Rogue's performance and improves the heat input control, to minimize thin gauge materials distortion , facilitate out-of-position welding with no undercuts and reducing spatter, thus helping to effectively avoid a number of welding defects. Rogue ES can TIG weld mild-steel or stainless steel via "LIVE TIG" functionality (TIG torch sold separately) for even more versatility.
