Miller XMT 304Features

  • Wind Tunnel Technology™ protects electrical components and PC boards from contamination.
  • Fan-On-Demand™ cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled through machine.
  • Lift-Arc™ allows TIG starting without the use of high-frequency. Starts the arc without contaminating the weld with tungsten.
  • Adaptive Hot Start™ increases the output amperage at the start of a weld if necessary, eliminating electrode sticking.
  • 115 VAC auxiliary power provides 10 amps of circuit-breaker-protected power for water circulators, etc. Standard on XMT 456, optional on XMT 304 and XMT 350 CC/CV models only.
  • Lightweight, aerospace-grade aluminum case offers protection with the benefit of reduced weight.
  • Inverter arc control technology provides greater puddle control for superior 6010 Stick electrode performance.
  • Line voltage compensation keeps welding output constant even if input power varies by +/-10%. XMT 350 models further expand line voltage compensation on 460 VAC to an amazing +37%, -59%.
  • Process selector switch reduces the number of control setup combinations without reducing any features.
  • Large, dual digital meters are easy to view and are presettable to ease setting weld output.
  • Pulsed MIG capabilities with optional Optima control reduces spatter and distortion, allows better out-ofposition puddle control, and provides potential reduction of fume particle emission (not available on XMT 350 VS).
