W7003220 - Thermal Arc W7003220 8-Pin Remote Socket with Harness for 201TS/161STL

Official Repair Part for Thermal Arc Inverters

The W7003220 8-Pin Socket with Harness is the authorized replacement receptacle for Thermal Arc 201TS and 161STL inverter welding power sources. This component is located on the front panel of the machine and serves as the interface for 8-pin remote controls, such as TIG foot pedals and torch-mounted amperage sliders. In professional welding environments, these connectors are subject to significant mechanical stress. If your machine no longer detects your remote or if the connection feels loose, this complete socket and harness assembly is the required fix.

Technical Specifications & Installation

This assembly features a standard 8-pin configuration used by specific Thermal Arc / ESAB models. It is not a universal connector; it is keyed and wired specifically for the 201TS and 161STL logic boards. The unit comes complete with the color-coded wiring harness attached, which routes from the back of the socket to the main PCB or control board inside the machine. Replacing this part typically involves removing the machine's cover, disconnecting the old harness from the board, unscrewing the socket from the front panel, and installing the new unit in reverse order. Always ensure the machine is unplugged and capacitors are discharged before attempting internal repairs.

Maintain Precision Control

For TIG welding applications, precise amperage control is paramount. A faulty socket can introduce resistance or signal noise, causing erratic arc behavior or unresponsive controls. By installing the W7003220, you eliminate these variables, ensuring that the signal from your foot pedal is transmitted accurately to the power source. This part is built to withstand the rigors of industrial use, featuring a robust housing and high-quality contact pins that resist oxidation and wear.
