Miller Deltaweld 500 MIG Welder Power Source, ArcConnect, 230/460V 3-Phase
The Miller Deltaweld 500 is a three-phase MIG welder power source with ArcConnect, Accu-Pulse and digital meters, delivering up to 650 A at 10-44 V from 230/460 V input. This version has no 14-pin receptacle and connects through ArcConnect cables, and it reaches its full capability when paired with an Intellx or Intellx Pro wire feeder.
Accu-Pulse gives precise control of the pulse arc and the molten puddle, and in many applications it can raise wire feed speed and deposition by 20 to 25 percent. ArcConnect's high-speed signals improve weld performance and allow the point-of-use controls to sit at the feeder. Digital meters and auxiliary power are standard, and a dedicated CC gouge mode handles carbon arc gouging with carbons up to 3/8 in. EZ-Set parameters, Wind Tunnel Technology and Fan-On-Demand round out the features.
An Intellx feeder adds jog/purge controls, arc control, remote voltage and digital meters, while the Intellx Pro also runs stainless, flux-cored and metal-cored wire plus other wire and gas types. Intellx drive systems use balanced-pressure drive rolls that feed the wire straight, and the accu-mate connection keeps the gun aligned in the drive-roll carrier. The power source weighs 145 lbs and measures 22.36 in. H x 15.35 in. W x 31.65 in. L.
