300688 - Miller RJ45 to 14-Pin Foot Pedal Adapter for Diversion and Multimatic

Connect Industrial Controls to Compact Welders

The Miller 300688 Adapter Cord is a critical interface component designed to bridge the gap between compact welding power sources and industrial-grade remote controls. Specifically engineered for Miller Electric machines, this adapter facilitates the connection of standard 14-pin remote controls to power sources equipped with an RJ45 (jack-style) remote receptacle. This component is essential for professional fabricators and serious hobbyists who wish to utilize high-performance peripherals with their portable welding units.

Broad Compatibility and Application

This adapter is primarily designed for use with the Miller Diversion™ 165, Diversion™ 180, and the Multimatic™ 215 multi-process welders. It is also compatible with the Hobart® E-Z TIG™ series. These machines typically come with an RJ45 port intended for specific, often lighter-duty, foot controls. By installing the 300688 Adapter Cord, operators can bypass these limitations and connect Miller’s robust line of 14-pin industrial foot controls and fingertip remotes. This upgrade path allows for greater precision, durability, and control responsiveness during critical TIG welding applications.

Wireless Capability Expansion

One of the significant advantages of this adapter is its ability to interface with Miller’s wireless control systems. The 14-pin receptacle on the adapter accepts the Miller 14-pin wireless receiver, enabling the use of the #300429 Wireless Remote Foot Control and the #300430 Wireless Hand Control. This feature significantly improves workplace safety and convenience by eliminating cable clutter and allowing the welder to position themselves optimally without being tethered by a short control cord.

Durable Construction

Measuring 12 inches in length, the cord provides just enough reach to relieve strain on the machine's port while keeping the connection point accessible. As a genuine Miller Electric product, it is built to withstand the rigors of a welding environment, featuring high-quality insulation and secure connectors that ensure consistent signal transmission for arc control. Whether upgrading for better ergonomics or integrating existing industrial equipment with a new portable machine, the Miller 300688 Adapter Cord is the reliable solution for seamless connectivity.
