Miller Deltaweld 500 Power Source W/14-PIN (575V) (907786001)

This Deltaweld 500 power source is the 575V version, built for shops running higher-voltage three-phase service. Like its lower-voltage sibling, it ships bare rather than on a cart, tipping the scale at 145 lbs.

One power source, open feeder choice

Both a 14-pin plug and ArcConnect cabling sit on the back panel here, which matters most for a shop standardizing one feeder style across several machines rather than buying a feeder bundled sight-unseen with the power source. The older 14-pin standard works with legacy feeders and accessories, while ArcConnect carries the newer point-of-use signaling that an Intellx or Intellx Pro feeder relies on.

Numbers that matter here

Rated output holds 100% duty through 500A, falling to 60% at a 575A peak, across a 20-650A, 10-44V span on 575V three-phase power. A gouge mode rated to 3/8″ carbons ships standard, and Accu-Pulse plus Wind Tunnel Technology with Fan-On-Demand round out the feature set.

Miller backs this power source with a manufacturer's warranty, suited to Career Welder-level work. Before ordering, confirm the feeder and running gear separately, since this listing covers the power source alone.

Is this the 230V/460V or the 575V version? This listing is the 575V, three-phase-only power source. Does it include a feeder? No, an Intellx or Intellx Pro feeder pairs with it separately.
