OVERVIEW

Reliable Replacement for Lincoln MIG Guns

The Lincoln Electric S19725 Trigger Switch is an essential replacement component engineered specifically for the Magnum 100L and Magnum PRO 100L series of MIG welding guns. In the demanding environment of industrial and hobbyist welding, the trigger mechanism is often the most used moving part of the torch. Over time, mechanical wear, dust accumulation, or accidental impact can cause the switch to fail, leading to intermittent arc starts or a complete loss of function. This genuine-style replacement part ensures that your equipment is restored to its original factory specifications.

Constructed from high-durability materials, this switch assembly is designed to withstand the rigors of daily use. It features a robust internal spring mechanism that provides a crisp, tactile response, allowing the operator to maintain precise control over the welding process. The housing is molded to fit perfectly within the handle of the Magnum 100L series guns, ensuring that there is no play or movement during operation. This precise fitment is critical for maintaining the ergonomics of the torch and preventing operator fatigue during long welding sessions.

Installation of the S19725 is straightforward and can typically be performed with standard hand tools. By simply opening the gun handle case, removing the faulty unit, and connecting the new switch, operators can minimize downtime and avoid the expense of purchasing a completely new gun assembly. This part is compatible with a wide range of Lincoln Electric power sources that utilize the 100L gun, including many of the popular compact wire feeder welders found in automotive shops, maintenance departments, and home garages. Investing in a quality replacement switch ensures the longevity and safety of your welding setup.

Whether you are performing maintenance on a fleet of machines or fixing a single unit, the S19725 delivers the reliability professionals expect from Lincoln Electric compatible components. Ensure your arc starts instantly every time you pull the trigger with this high-performance replacement switch.
