2075223 - ESAB MT-400 MIG Gun Trigger Switch Lead Replacement

Get Your MT-400 Firing Again

Is your ESAB MT-400 MIG gun acting up? If you are pulling the trigger and getting nothing—or if the wire feeds intermittently—you might have a broken switch lead. The ESAB 2075223 Switch Lead is the direct replacement part you need to fix connection issues inside your torch handle. Welding in tough environments puts a lot of strain on your equipment, and the small wires inside the gun handle are often the first thing to break from constant twisting and pulling.

Don't struggle with a finicky trigger that ruins your rhythm. This replacement lead is built to the exact specs of your original gun, meaning it fits perfectly inside the handle and connects securely to your existing trigger switch. The insulation is tough enough to handle the heat and abrasion of the shop floor, ensuring your repair lasts. It’s a simple fix that saves you the cost of buying a whole new gun.

Why choose this part?

• Exact Fit: No guessing or modifying wires; it's made for the MT-400.
• Reliable Starts: Eliminates the frustration of pulling the trigger and getting no arc.
• Durable: Built to withstand the daily abuse of professional welding.

Keep your production line moving and your welds consistent by replacing worn-out internal leads with genuine ESAB parts.
