907786001 - Miller Deltaweld 500 MIG Welder 575V with 14-Pin Connector

Industrial Power and Precision: Miller Deltaweld 500 575V

The Miller Deltaweld 500 (575V model with 14-Pin) represents a significant evolution in industrial welding power sources, engineered specifically for heavy equipment manufacturing, railcar production, and general fabrication. This unit (SKU: 907786001) is designed to operate on 575V 3-phase input power, delivering a robust 500 amps of welding output. It distinguishes itself by offering a seamless bridge between legacy systems and modern welding technologies. The inclusion of the standard Miller 14-Pin receptacle ensures immediate backward compatibility with existing wire feeders, allowing facilities to upgrade their power sources without rendering their current peripheral equipment obsolete.

At the core of the Deltaweld 500 is Miller's advanced ArcConnect™ technology, a next-generation communication protocol that enhances weld performance and enables point-of-use controls to be located directly at the feeder. This system is housed within a chassis utilizing Wind Tunnel Technology™, a proprietary design that routes internal airflow to protect sensitive electrical components and PC boards from dirt, dust, and debris. This significantly improves reliability in harsh industrial environments. Furthermore, the Fan-On-Demand™ cooling system operates only when necessary, reducing airborne contaminants pulled through the machine, lowering noise levels, and conserving energy.

For applications requiring versatility, this power source is not limited to standard MIG and Flux-Cored processes. It features a dedicated constant current mode specifically designed for air carbon arc gouging, capable of handling carbons up to 3/8 inch (9.9 mm) in diameter. When paired with an Intellx Pro feeder (sold separately), the system unlocks Pulsed MIG capabilities, providing a 28-percent wider operating window and a more forgiving arc. This makes the Deltaweld 500 an exceptionally adaptable solution for facilities processing stainless steel and steel, ensuring high-quality welds regardless of operator skill level variations.
