0365840880 - ESAB PSF Series MIG Gun Trigger Assembly with Spring

Restore Precision to Your Welding Operations

The ESAB PSF Trigger With Spring (0365840880) is an essential replacement component designed to keep your ESAB PSF series MIG guns operating at peak performance. In the demanding world of industrial welding, the trigger is one of the most frequently used and abused parts of the torch. Over time, the constant clicking, exposure to workshop debris, and mechanical wear can lead to a trigger that sticks, fails to initiate the arc, or loses its tactile responsiveness. This genuine replacement kit addresses those issues directly, providing a fresh start for your equipment.

Designed specifically for the popular PSF line of torches, this assembly includes both the molded trigger piece and the critical return spring. The spring is vital for ensuring the trigger snaps back immediately after release, cutting off the wire feed and arc instantly for safety and precision. Without a functioning spring, welders may experience dangerous "run-on" where the wire continues to feed, or they may struggle with hand fatigue due to poor resistance. By replacing the entire assembly, you ensure that the mechanical action is smooth, consistent, and reliable.

Installation is straightforward, allowing maintenance teams or individual operators to swap out the faulty part quickly and get back to work with minimal downtime. Using genuine ESAB parts guarantees that the fit within the handle is exact, preventing the rattling or misalignment often seen with generic aftermarket copies. Whether you are refurbishing an older torch or fixing a sudden breakdown, this trigger assembly is the cost-effective solution to extend the life of your valuable welding assets.

Don't let a small plastic part compromise your weld quality. A crisp, responsive trigger allows for better tack welding, more precise bead starts, and overall improved operator comfort. Trust in ESAB's engineering to maintain the high standards your projects require.
