Miller Dimension 812 Multi-Process Welder (907361)

A proven heavy-industrial power source for high-deposition welding and extended arc-on time. The Miller Dimension™ 812 is designed for fabrication, mining, shipbuilding, structural steel and maintenance operations that need dependable multi-process performance at a true 100% duty cycle.

High-output industrial performance

The Dimension 812 supports MIG, flux-cored, stick and TIG welding, plus air carbon-arc cutting and gouging. Its broad CC/CV output range lets one power source cover thick-section fabrication, repair and production work with stable, repeatable arc performance.

• 650 A at 44 VDC, 100% duty cycle
• CC output range: 50–815 A
• CV output range: 10–65 V
• 380/400/440 V, three-phase, 50 Hz input
• IP23S protection rating
• Rated for carbon-arc gouging with carbons up to 12 mm

Designed to keep working

Line-voltage compensation helps maintain consistent weld performance when incoming power varies. Fan-On-Demand™ reduces unnecessary fan noise and limits the amount of dust drawn through the machine. Clear digital meters display preset and actual voltage and amperage, while built-in stick arc control helps operators fine-tune the arc in difficult positions.
