The Trigger Complete (SP4/SP5) is a high quality replacement switch assembly engineered for Tweco® Spray Master style MIG torches. In high volume production welding, the trigger is subjected to constant mechanical wear and potential heat damage. This complete unit restores the "snap" and responsiveness of your torch, preventing frustrating wire feed stutters or "sticking" arcs.
Designed to fit both the SP4 (400A) and SP5 (500A) series, this trigger features a reinforced internal micro switch and a contoured finger pad. It is built to operate flawlessly even when the operator is wearing heavy duty welding gloves. This is a "plug and play" component, allowing for rapid field repairs to keep your production line moving without the need for complex rewiring.
