300432 - Miller RFCS-RJ45 TIG Foot Pedal for Diversion and Multimatic

Precise Control for TIG Welding Applications

The Miller RFCS-RJ45 Remote Foot Control (300432) is a high-quality amperage and contactor control device designed to enhance the functionality of select Miller and Hobart welding power sources. Engineered for precision, this foot pedal allows welders to remotely adjust amperage output while welding, a critical feature for TIG applications where heat management is paramount. By depressing the pedal, the operator activates the contactor to start the arc and increases the amperage; releasing the pedal lowers the amperage and eventually terminates the arc. This dynamic control is essential for crater filling and preventing burn-through on thin materials.

Compatibility and Connectivity

This remote control is specifically outfitted with an RJ45 jack-style plug, making it directly compatible with a range of popular machines without the need for adapters. It is the designated foot control for the Miller Diversion™ 165 and 180 TIG welders, as well as the Miller Multimatic™ 215 multi-process welder. Additionally, it serves as the correct remote for Hobart E-Z TIG™ and Hobart Multi-Handler™ 200 machines. The plug-and-play nature of the RJ45 connection ensures a secure signal transmission for reliable performance.

Ergonomics and Reach

The unit comes equipped with a 14-foot (4.3 meter) cord, providing ample length for operators to position themselves comfortably around large workpieces or fixtures. The pedal itself is built to withstand the rigors of a welding environment, featuring a robust housing and a responsive mechanism that offers smooth travel for fine current adjustments. Whether you are working in a garage, a fabrication shop, or on-site, the RFCS-RJ45 provides the tactile feedback necessary for high-quality TIG welds.

Essential for Quality Welds

Using a foot control like the RFCS-RJ45 significantly improves weld quality by freeing up the operator's hands to focus solely on torch manipulation and filler metal addition. It is particularly beneficial when welding aluminum, where the material's thermal conductivity requires rapid heat input changes. This accessory is a genuine Miller part, ensuring it meets the manufacturer's strict standards for durability and performance.
