0369611880 - ESAB Replacement Trigger Switch for PSF 160 and PSF 250 MIG Guns

Get Your Click Back: ESAB PSF 160/250 Trigger Switch

There is nothing more frustrating than a MIG gun that won't fire when you pull the trigger. If you are running an ESAB PSF 160 or PSF 250 torch and experiencing intermittent starts, sputtering wire feed, or a trigger that feels "mushy," the culprit is likely a worn-out switch. The ESAB Mechanical Switch (0369611880) is the direct replacement you need to fix the problem and get back to laying beads. This isn't a generic knock-off; it's the genuine article designed to fit your handle perfectly.

Welding triggers take a beating. Dust, metal shavings, and constant clicking eventually wear out the mechanical contacts inside. When that happens, you might find yourself wiggling the trigger just to get the arc to strike. Installing this replacement switch restores that crisp, responsive "click" you had when the torch was new. It ensures that when you pull the trigger, the gas flows, the contactor closes, and the wire feeds instantly—every single time. It’s a small part that makes a massive difference in your daily welding rhythm.

Installation is straightforward for anyone comfortable with basic tool repairs. You simply open up the handle casing of your PSF torch, disconnect the old switch, and seat this new one in its place. Because it is an OEM part, the dimensions are exact, meaning no filing or forcing is required. Don't let a cheap plastic switch hold up your project or compromise your weld quality. Swap it out with a fresh ESAB mechanical switch and restore the reliability of your trusty PSF torch.
