Miller XMT 650 ArcReach Multiprocess Welder with Polarity Reversing, 380/460V
The Miller XMT 650 ArcReach Multiprocess Welder with Polarity Reversing lets the operator flip polarity from the control panel instead of swapping leads between the positive and negative terminals. This three-phase power source runs on 380/460 V, and ArcReach puts full control at the feeder or a remote, even hundreds of feet away.
Cable Length Compensation (CLC) corrects voltage for the weld cable length, so the voltage an operator sets is the voltage delivered at the arc. The ArcReach 16 wire feeder switches between welding and gouging at the point of use, Auto-Process Select sets the process from the polarity applied to the weld accessory, and Adjust While Welding (AWW) allows parameter changes with the arc on. Removing the ArcReach accessory returns the power source to its previous settings.
Wind Tunnel Technology, Fan-On-Demand and an IP23 rating make the XMT 650 ArcReach rugged and durable, and like every XMT 650 it is three-phase only. The power source weighs 187 lbs, measures 28.2 in. high, 16.7 in. wide and 31.6 in. deep, and comes as the power source alone.
