OVERVIEW

Get Back to Welding with the Tweco 2000-2090 Trigger

There is nothing more frustrating than a MIG gun that won't fire when you pull the trigger. Whether you are dealing with a switch that sticks, requires excessive pressure to activate, or works intermittently, a failing trigger kills your productivity and weld quality. The Tweco 2000-2090 Trigger Assembly is the direct replacement you need to fix your gun and get back to laying beads. Designed specifically for the guns you use every day, this trigger restores the crisp, responsive feel of a brand-new torch.

This trigger is the standard replacement for the most popular guns in the industry. If you are running a Tweco Spray Master, a Classic No. 2 through No. 5, or an Eliminator series gun, this is likely the part you need. It is built tough to handle the abuse of a welding shop. The plastic is durable enough to survive being dropped on concrete, and the spring action is tuned to provide just the right amount of resistance—light enough to prevent finger fatigue during long welds, but firm enough to prevent accidental arc starts.

Replacing your trigger shouldn't turn into an all-day project. The Tweco 2000-2090 is designed for a quick swap. Once you open up your MIG gun handle, the old trigger lifts out, and the new one drops right in. The wire connections are simple, usually involving standard slide-on connectors. You don't need to be a certified electrician to install it; you just need a screwdriver and a few minutes. Don't let a cheap plastic switch hold up a major fabrication project.

Using genuine parts like this trigger also ensures safety. A worn-out trigger can sometimes stick in the "on" position, feeding wire and keeping the arc live when you don't expect it, which is a major safety hazard. Replacing a dodgy trigger is cheap insurance for you and your shop. Keep a spare 2000-2090 in your toolbox so you are never left stranded by a broken switch in the middle of a job.
