OVERVIEW

Genuine Thermal Arc TIG Control Replacement

The Thermal Arc A3118126 Control Button and Harness is a specialized replacement component designed to restore functionality to your TIG welding setup. Engineered specifically for Thermal Arc power sources utilizing an 8-pin remote connection, this assembly ensures seamless communication between the torch operator and the machine. The unit consists of a high-durability control button, a robust wiring harness, and a precision-molded 8-pin connector plug.

In industrial environments, torch controls are subject to frequent mechanical stress and environmental wear. A failing control switch can lead to erratic arc initiation or a complete loss of remote capability, resulting in downtime and reduced weld quality. This OEM part is manufactured to the original specifications, ensuring that the electrical resistance and pin configuration match your equipment perfectly. The harness is insulated to protect against heat and abrasion common in welding zones.

Installation is straightforward for technicians familiar with TIG torch assembly. The 8-pin connector interfaces directly with the remote receptacle on compatible Thermal Arc inverters. Whether you are repairing a damaged torch or upgrading a standard torch to include hand controls, this harness provides the necessary link for reliable contactor closure. Trust in genuine Thermal Arc components to maintain the safety and performance standards of your welding operations.

Key Technical Aspects:

  • Connector Standard: 8-Pin Amphenol style for secure locking and signal integrity.
  • Switch Type: Momentary contact for arc start/stop functionality.
  • Cable Quality: Flexible, high-strand count wire designed for repeated flexing.

FAQ

This part is designed for Thermal Arc welding machines that utilize a standard 8-pin remote control receptacle. Please verify your machine's manual for pinout compatibility.

No, this SKU includes the control button, harness, and 8-pin connector only. The torch handle and body are sold separately.

This is typically a momentary switch designed for standard 2T/4T TIG welding operations.

This is a hand control that mounts to the torch. It replaces the function of a foot pedal for on/off arc control, which is ideal for out-of-position welding.

The button assembly typically straps or clips onto the torch handle, and the harness runs down the cable cover to plug into the machine.

Yes, this is a genuine Thermal Arc replacement part.

Generally no, unless the machine uses the exact same 8-pin Amphenol pinout configuration as Thermal Arc. Adapters may be required for other brands.
