129337 - Miller RMLS-14 Fingertip Rocker Switch Control (14-Pin)

Miller RMLS-14 Rocker Switch Fingertip Control (129337)

The Miller RMLS-14 Rocker Switch (SKU: 129337) is a premium fingertip control accessory designed to enhance the functionality of Miller solid-state welding power sources. Engineered for professional TIG welding applications, this remote switch provides reliable contactor control directly from the torch handle, eliminating the need for a foot pedal in out-of-position welding scenarios. The unit connects via a standard 14-pin plug, making it compatible with a wide range of Miller equipment manufactured after serial number JK674521, including Dynasty, Maxstar, Syncrowave, and XMT series machines.

This control unit features a versatile dual-action rocker switch mechanism. Operators can push the switch forward to engage "maintained" contact, which keeps the contactor closed (arc on) until the switch is returned to the center position—ideal for long, continuous welds. Alternatively, pulling the switch backward engages "momentary" contact, where the arc remains active only as long as the operator holds the switch, providing precision control for tacking or short welds. The RMLS-14 includes a durable 26.5-foot (8-meter) cord, offering significant reach and flexibility within the workspace.

Compatibility and Use

The RMLS-14 is specifically designed to fasten securely to TIG torch handles, placing control right at the welder's fingertips. It is an essential accessory for applications where foot controls are impractical, such as climbing ladders, working in confined spaces, or welding in awkward positions. The robust construction ensures longevity in industrial environments, while the plug-and-play 14-pin connection ensures quick setup with compatible power sources.
