W4013200 - ESAB 8-Pin Remote Foot Control for 186/141 Series Welders

Technical Overview of the ESAB W4013200 Foot Control

The ESAB W4013200 is a dedicated remote foot control unit designed to interface with specific ESAB and Thermal Arc inverter power sources. Engineered as a light-duty controller, it provides the operator with dual functionality: remote contactor activation and linear amperage regulation. The unit connects to the power source via a hardwired 15-foot cable assembly terminated with a standard 8-pin male aviation plug, ensuring a secure and reliable signal transmission during welding operations.

Functionally, the pedal operates on a depression mechanism. Initial pressure on the pedal closes the contactor circuit, signaling the machine to initiate the arc and activate the gas solenoid for shielding. As the operator depresses the pedal further, the potentiometer within the unit increases the welding current proportionally, up to the maximum limit set on the machine's front panel. Releasing the pedal reverses this process, ramping down the current (if downslope is enabled on the machine) and opening the contactor to terminate the arc while triggering the post-flow gas cycle. This dynamic control is critical for managing heat input in complex TIG applications.

Compatibility is a key specification for this device. It is explicitly manufactured to support the ESAB 186 and 141 series welders, as well as the legacy Thermal Arc 186 AC/DC units. Manufacturer data also indicates suitability for Renegade ES 300i and ET 300ip power sources, broadening its utility across the ESAB portable inverter lineup. The 15-foot reach allows for adequate separation between the power source and the workpiece, facilitating better shop layout and ergonomics.
