OVERVIEW

Reliable Arc Control with the Weldcraft SW-3

Upgrade or repair your TIG torch with the genuine Weldcraft SW-3 Momentary Switch. If you are tired of finicky switches that stick or fail to start the arc when you need it most, this replacement part is the industry standard for reliability. Designed to fit comfortably on your torch handle, it puts the power of the machine right at your fingertips, allowing for easy tacking and long seam welding without being tethered to a foot pedal.

Built for the Shop Environment
Welding shops are tough on electronics. That's why the SW-3 includes a durable rubber boot that covers the switch button. This simple addition makes a huge difference, keeping out the grit, grime, and metal shavings that destroy lesser switches. Whether you are working in a garage or a heavy fabrication plant, this switch stands up to the abuse of daily use.

Universal Compatibility
One of the best features of the SW-3 is its versatility. It is designed to work with a vast array of TIG torch handles, including the popular WP-17, WP-18, and WP-26 series, as well as many others. The momentary action gives you precise control—press to weld, release to stop. It is the perfect solution for bump welding, tacking, or working on ladders and in tight spaces where a pedal just isn't an option. Get your torch back in top fighting shape with this essential replacement part.
