Lincoln Electric OEM switches and circuit breakers from WeldingMart restore safe electrical function to Lincoln MIG, TIG, stick, and engine-driven welders. A tripping circuit breaker on a Lincoln welder typically indicates an overload condition, a failing breaker, or a downstream short - replacing the breaker without diagnosing the root cause will not fix the underlying issue. Call WeldingMart if you need application guidance before ordering.

WeldingMart stocks Lincoln Electric toggle switches, rocker switches, thermal circuit breakers, and auxiliary switches for the Ranger, Power MIG, and Idealarc series. Order by Lincoln part number or call with your machine model and serial number. Most switch and breaker stock ships next business day.
