75057012 - American Weldquip Smoke Gun Trigger Micro Switch

Fix Your Trigger, Fix Your Weld

There is nothing more annoying than a MIG gun trigger that cuts out halfway through a bead or requires a "magic touch" to get the arc started. If you are running an American Weldquip Smoke Gun and experiencing trigger issues, the 75057012 Micro Switch is the direct replacement you need to get back to smooth welding. Fume extraction guns are heavy-duty tools designed to keep the air clean, but they take a beating in the shop. The trigger switch is the one moving part you use thousands of times a day. Eventually, the internal contacts wear out or the spring mechanism fatigues. When that happens, you don't need a new gun—you just need this switch.

This isn't a generic electronics part you have to jam into the handle with electrical tape. This is the genuine American Weldquip micro switch made specifically for their smoke extraction guns. It drops right into the molded slot in the handle, ensuring the plastic trigger lever hits it perfectly every time. The tactile click is crisp and responsive, giving you that positive feedback you need to know the gas is flowing and the wire is feeding. Installing it is generally a straightforward repair: open up the handle case, disconnect the old switch leads, connect the new ones, and seat the switch. It’s a ten-minute job that saves you from fighting your equipment all day.

Why settle for intermittent starts or a trigger that sticks? A bad switch can cause burn-backs if it flickers off while you're welding, or bird-nesting if it doesn't stop the feed instantly when you let go. The 75057012 restores the snappy, reliable on/off control your gun had when it was new. Whether you are a maintenance tech fixing up the shop's gear or a welder tired of wiggling the trigger to get an arc, this part is the solution. Keep your American Weldquip smoke gun running like a champ and keep the fumes away from your face with a trigger you can trust.
