20402093 - Tweco 2040-2093 Replacement Trigger Switch Blades Pair

Restore Your MIG Gun's Performance

There are few things more frustrating in the shop than a MIG gun trigger that has a mind of its own. You pull the trigger, and... nothing. Or worse, it sputters, starts and stops, or sticks in the 'on' position. Before you throw the whole gun across the shop or spend hundreds on a replacement, check your switch blades. The Tweco 2040-2093 Switch Blades Set is the exact fix you need to get that crisp, reliable 'click' and instant arc start back in your hand. These are the actual metal contacts that touch together when you squeeze the trigger, and like any moving part, they eventually wear out.

Designed specifically for the legendary Tweco Classic and Spray Master guns, these replacement blades are built to last. They are made from durable conductive metal that resists bending and corrosion, ensuring that when you want to weld, the machine responds instantly. Installing them is a breeze; usually, it just involves opening up the handle case, sliding out the old, worn-out blades, and popping these new ones in. It’s a five-minute repair that can save you the cost of a new gun and the headache of troubleshooting intermittent electrical gremlins.

Whether you are a professional fabricator running beads all day or a hobbyist working on a weekend project, keeping your equipment in top shape is key to quality welds. A faulty trigger can lead to poor starts, porosity, and ruined workpieces. Keep a set of these Tweco switch blades in your toolbox. They are an inexpensive insurance policy against downtime, ensuring that your trusty Tweco gun is always ready to lay down metal when you are.
