Multi-process welders are some of the most versatile welders around – they combine the capabilities of a constant current CC power source (stick welder, TIG welder) and a constant voltage CV power source (MIG welder) into a single unit. Typically multi-process welders can be used for arc gouging and submerged arc welding as well. Engine-driven welders are the ultimate multi-process welders – not only can they be utilized as a stick welder, TIG welder or MIG welder, they’re portable too!
