Century Mig Welder

A USAWELD Electronic Relay which is a direct replacement for Century p/n 216-055-666. When these fail, sometimes your wire is hot all of the time, and sometimes you have no arc. If you have no arc, the problem could also be in your PCB. Verify you have voltage across the input terminals with the trigger pulled, and no voltage when the trigger is released. If you do not have voltage with the trigger pulled - the problem is probably in the PCB. We also include a small packet of heat transfer compound with this relay for correct installation. This Relay fits the following Century Welders: 117-001, 117-002, 117-003, 117-004, 117-005, 117-006, 117-007, 117-010, 117-011, 117-012, 117-015, 117-019, 117-020, 117-021, 117-022, 117-026, 117-027, 117-028, 117-029, 117-030, 117-031, 117-038, 117-039, 117-040, 117-041, 117-043, and 117-044 Since this is an electrical part, there are no returns on this part.
