Miller Electric Mfg. LLC’s XMT 650 ArcReach systems include an XMT 650 ArcReach power source and ArcReach 16 wire feeder. The systems are for structural fabrication, steel erection and shipbuilding. Configurations are available for field and shop applications, with remote polarityreversing power source and non-polarity-reversing power source models, both compatible with the wire feeder. The polarity-reversing model lets operators switch polarity at the feeder with the push of a button, so they can quickly change between welding and gouging without having to walk back to the power source.
