003-0585 - MK Products 003-0585 Trigger Assembly for Prince XL & Xtra Lite Guns

Restore the Feel of Your Favorite Gun

There is nothing more frustrating than a welding gun with a sticky, intermittent, or broken trigger. When you are in the middle of a long bead on an aluminum tank or trailer, you need your gear to work as hard as you do. The MK Products 003-0585 Trigger Assembly is the direct OEM replacement for your Prince XL (PXL) or Xtra Lite push-pull gun, designed to bring back that crisp, reliable "click" you felt when the gun was new.

MK Products guns are legendary in the industry for their ability to feed aluminum wire smoothly over long distances. However, the trigger is a moving part that sees thousands of cycles and is often exposed to dust, grime, and rough handling. Over time, the internal contacts can wear out, or the plastic mechanism can fatigue, leading to those annoying moments where you pull the trigger and... nothing happens. Or worse, the arc stutters. This replacement assembly swaps out the entire mechanism, solving electrical and mechanical trigger issues in one go.

Don't settle for jury-rigged fixes or generic switches that don't fit quite right. This is the genuine article from MK Products. It fits perfectly into the handle of your Xtra Lite or Prince XL, ensuring the ergonomics remain exactly how you like them. The installation is simple enough to be done on the bench, meaning you can fix your gun during a break or between shifts and be back to welding with confidence.

Whether you are running a busy fab shop or working on specialized custom projects, reliable equipment is your bread and butter. Keep a spare 003-0585 in your maintenance kit so that a broken switch never stops your production. Trust in OEM quality to keep your arcs smooth and your beads consistent.
