Details & Inspection Notes

Strip the cart and feeder away and this listing is the Deltaweld 500 power source on its own. It carries a 14-pin receptacle alongside ArcConnect cabling, so a shop is not locked into one feeder style, and it ships light enough, at 145 lbs and 22.36″H by 15.35″W by 31.65″L, to mount into an existing setup rather than arrive as a full cart package.

Why both connection types matter

Older feeders and accessories expect the 14-pin standard, and this power source still has that plug. Newer point-of-use control, the kind an Intellx or Intellx Pro feeder uses, runs over the ArcConnect cable instead. Having both on one chassis means the feeder gets picked separately rather than bundled sight-unseen.

Numbers that matter here

Output spans 20-650A at 10-44V on three-phase, 230/460V input, with duty cycle: 500A gets the full 100%, while 575A settles for 60%. Gouging is rated to 3/8″ carbons. Accu-Pulse technology refines pulse-arc control for a cleaner puddle, and Wind Tunnel Technology with Fan-On-Demand keeps dust out while limiting fan noise.

Miller ships this as the power source with digital meters only, built for Career Welder-level work, and a manufacturer's warranty is included.

Does this listing include a wire feeder? No, this is the Deltaweld 500 power source by itself; an Intellx or Intellx Pro feeder is needed to weld. Which feeder style does it support? Either, since it carries both a 14-pin receptacle and ArcConnect cabling.

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.
