2075216 - ESAB MT-400 MIG Gun Trigger Lead and Plug Kit

ESAB 2075216 Switch Lead & Plug Assembly for MT-400

The ESAB 2075216 is a specialized Switch Lead and Plug Assembly designed for the maintenance and repair of MT-400 series MIG guns. As a critical component of the welding gun's control circuit, this assembly facilitates the electrical signal transmission from the mechanical trigger switch in the handle to the wire feeder or power source. Over time, internal leads can suffer from fatigue, breakage, or insulation damage due to the constant flexing and movement associated with manual welding operations. This OEM replacement part ensures that the control signal remains uninterrupted, preventing issues such as failure to initiate the arc or intermittent wire feeding.

Manufactured to ESAB's precise specifications, this assembly includes the necessary cabling and the specific plug connector required for the MT-400 system. The insulation materials are selected to withstand the harsh industrial environment, offering resistance to heat, abrasion, and oil. Installing genuine ESAB parts guarantees compatibility with existing equipment, maintaining the safety and performance standards of the original tool. This part is identified by the SKU 2075216 and is essential for technicians performing comprehensive service on Tweco-style or ESAB MT-400 MIG torches.

Proper maintenance of the trigger circuit is vital for operator safety and process quality. A compromised switch lead can lead to unexpected stops in welding or, in rare cases, unintended activation if shorted. By replacing the entire lead and plug assembly, maintenance personnel can restore the gun to factory-level reliability. This component is supplied as a single unit, ready for installation into the gun handle and cable assembly.
