Miller Dimension 650 ArcReach Multi-Process Welder 380/460V

Heavy-industrial output in a smaller, more efficient power source. The Miller Dimension™ 650 with ArcReach® is engineered for fabrication, construction, shipbuilding, pressure-vessel, rail and heavy-equipment work that ranges from precise thin-metal welding to high-amperage production and gouging.

High output, full duty cycle

The Dimension 650 delivers 650 A at a 100% duty cycle and covers MIG, flux-cored, stick, TIG, submerged arc and air carbon-arc cutting and gouging. ArcReach capability allows compatible feeders and remotes to adjust parameters at the weld joint without a separate control cable, saving walking time and helping operators stay focused on the work.

• 650 A at 44 VDC, 100% duty cycle
• Output range: 15–815 A, 10–65 V
• 380/460 V, three-phase, 50/60 Hz input
• IP23 protection rating
• Approx. 71.7 kg net weight
• Approx. 716 × 424 × 803 mm (H × W × D)

Made for harsh environments

A corrosion-resistant aluminium enclosure, protected internal airflow and Fan-On-Demand™ cooling improve reliability while reducing unnecessary noise and contaminant intake. High electrical efficiency and a strong power factor reduce input demand compared with older transformer-based industrial machines.

Lead-time note: source availability indicates an estimated 12–14 week lead time from cleared payment. Feeder, torch, leads, remote equipment and running gear may be optional. Confirm the exact ArcReach configuration, input supply, package contents, availability and lead time before ordering.
