9SS18932 - Lincoln Electric S18932 Replacement Trigger Switch for Magnum PRO 250L/100SG/250SP

Fix Your Trigger, Fix Your Weld

There is nothing more frustrating than a MIG gun that won't fire when you pull the trigger. If you are running a Lincoln Magnum PRO 250L, 100SG, or 250SP and experiencing intermittent starts or a completely dead switch, the S18932 Trigger Switch is exactly what you need to get back in action. This is the direct replacement part intended to swap out your old, worn-out mechanism and restore that crisp, responsive click you expect from a quality tool.

Welding triggers take a beating. They get clicked thousands of times, often with gloved hands that might be oily or covered in grime. Eventually, the internal contacts can corrode or the spring mechanism can fatigue. When that happens, you might find yourself wiggling the trigger just to keep the arc going, which leads to poor weld quality and frustration. This replacement assembly solves that problem instantly. It is built tough to handle the daily grind of the shop, ensuring that when you pull the trigger, the gas flows and the wire feeds every single time.

Don't settle for rigging up a temporary fix or struggling with a faulty gun. Swapping out the trigger is one of the most cost-effective repairs you can do to extend the life of your MIG gun. This unit fits perfectly inside the handle of the compatible Magnum PRO models, so you don't have to worry about modifying the casing or splicing weird wires. It’s a plug-and-play solution designed to get you back under the hood and laying beads as quickly as possible.

Whether you are a hobbyist using the 100SG spool gun for aluminum projects or a professional fabricator relying on the 250L for daily steel work, keeping a spare trigger switch in your toolbox is a smart move. It ensures that a small mechanical failure doesn't turn into a major work stoppage. Trust genuine Lincoln parts to keep your gear running smooth.
