042872 - Miller Process Selector Control for XMT 304

Optimize Your Welding Operations with the Miller Process Selector Control

The Miller Process Selector Control (042872) is a critical accessory designed to enhance the functionality and versatility of industrial welding setups, specifically those utilizing the XMT® 304 CC/CV Multi-Process Welding Power Source. In high-throughput fabrication environments, the ability to switch between welding processes efficiently can significantly impact productivity. This control unit provides a robust solution for managing complex welding stations, particularly those employing dual wire feeders or requiring frequent changes between Constant Current (CC) and Constant Voltage (CV) modes.

Engineered by Miller Electric, a leader in industrial welding technology, this device serves as a central hub for process management. It allows operators to change the welding process without the time-consuming and potentially hazardous task of manually swapping heavy welding cables. Furthermore, it includes essential features for Polarity Control, enabling the reversal of weld current polarity as dictated by the specific welding wire or electrode being used. This is particularly advantageous in shops that alternate between solid wires (typically DCEP) and self-shielded flux-cored wires (typically DCEN), or between TIG and Stick welding processes.

The unit is built to withstand the rigors of industrial environments. It comes equipped with a 115 VAC/2 Amp receptacle, providing convenient auxiliary power for tools or accessories directly at the control point. Connectivity is handled through two standard 14-pin receptacles and an included 10-foot 14-pin cord, ensuring seamless integration with the power source and feeders. By facilitating electrical isolation, the Miller Process Selector Control also adds a layer of safety and equipment protection, ensuring that current is only active where and when it is intended. For facilities looking to maximize the ROI on their XMT 304 fleet, this accessory is an indispensable upgrade.

Key Industrial Benefits:

• Efficiency: Reduces setup time between process changes.


• Versatility: Unlocks the full potential of multi-process power sources.


• Safety: Provides electrical isolation and secure connections.
