Details & Inspection Notes

Pair the ArcConnect-only configuration with 575V three-phase power and this is the listing: a bare Deltaweld 500 power source without a 14-pin receptacle, built for shops already wired for 575V service. Like the rest of the bare power source line, it weighs in at 145 lbs.

Single input voltage, simpler spec

This power source is built for 575V input only, which simplifies the decision for a shop that already runs 575V service elsewhere in the building. ArcConnect cabling sends point-of-use control out to an Intellx or Intellx Pro feeder over a single cable, with no 14-pin option on this unit.

Numbers that matter here

Duty cycle tops out at 100% for 500A and settles to 60% for 575A, over a 20-650A, 10-44V output range, with gouging good to 3/8″ carbons. Accu-Pulse sharpens the pulse arc, and Wind Tunnel Technology with Fan-On-Demand limit dust intrusion and fan noise.

Miller ships it as the power source alone, with digital meters included, and a manufacturer's warranty covers Career Welder-level use. A shop choosing this configuration still needs to add a feeder, a gun, and running gear before it can lay down a bead.

Does this unit run on the lower input voltages other Deltaweld 500 versions use? No, this configuration is rated for 575V input only. Is a feeder included? No, pair it with an Intellx or Intellx Pro feeder separately.

Welding Equipment Setup & Pre-Operation Checklist

  • Verify workshop mains voltage, circuit breaker rating, and phase match the welding machine specifications.
  • Inspect ground clamp cable, torch lead, and work cables for tight, clean, low-resistance connections.
  • Secure shielding gas cylinders upright with safety chains; inspect regulator and hose connections for gas leaks.
  • Confirm correct wire diameter, drive roll groove profile, and contact tip size match the spool installed.
