9703 - TIG Torch Clip-On On/Off Switch Control Cable, 27 ft, 6-Pin

Technical Specifications and Application

The LEN9703 TIG Torch Switch Assembly is a remote contactor control device designed for use with air-cooled and water-cooled TIG torches, specifically the industry-standard Series 9, 17, and 20 bodies. This unit functions as a momentary on/off switch (2-step logic), closing the contactor circuit to initiate the welding arc and opening it to terminate the weld. It is an essential accessory for applications where a foot amperage control is impractical, such as field welding, positional pipe welding, or overhead work.

The assembly is terminated with a 6-pin aviation-style plug (Amphenol type), a common configuration for remote control connections on many industrial power sources. The 27-foot (approx. 8.2 meters) control cable is shielded to prevent high-frequency (HF) interference from disrupting the signal or affecting machine performance. The switch mechanism is housed in a durable, molded plastic casing that clips directly onto the torch handle, providing a low-profile form factor that does not interfere with the operator's grip or torch manipulation.

Key Technical Features:

• Actuation: Momentary Push-Button (Start/Stop).
• Connector Pinout: 6-Pin configuration (Check machine manual for specific pin compatibility).
• Cable Type: Flexible, oil-resistant control cable.
• Strain Relief: Reinforced entry points at both the switch and plug ends to prevent conductor fatigue.

This switch is strictly a contactor control (on/off) and does not provide variable amperage adjustment (potentiometer) at the torch. It is ideal for use with machines set to panel control for amperage or for tacking operations where instant arc initiation is required without variable current ramping.
