Miller Spectrum 2050 Plasma Cutter 50ft Torch model# 903777013

This unit can be powered by any Miller welding generator with power
output of 8 KW or more, such as the Bobcat
™ or Trailblazer® .


Auto-Line automatically connects unit to any primary voltage from 208 to 575 volts, single-or three-phase, 50 or 60 Hz.

LVC ™ line voltage compensation provides peak performance power under variable input voltage conditions (176-630 V) for steady cuts and cleaner ending cuts.

Fan-On-Demand cooling system only operates when needed, reducing the amount of airborne dust/dirt pulled through the unit.

Wind Tunnel Technology prevents abrasive dust and particles from damaging internal components.

Can be powered by any Miller engine drive, with generator power (e.g. Bobcat™) or equivalent competitive equipment.

Power factor correction (PFC) uses input power more efficiently, ultimately using less energy.

Starts without high-frequency so it will not interfere with or damage controls or computer.

Blow Back Torch Design
The plasma arc is created by pulling an electrical arc between an electrode and tip. This process eliminates high frequency by forcing an electrical arc between the two pieces.

Pilot Arc Switch
The expanded metal mode allows operator to cut grates, chain link fence, and other perforated metals without retriggering the gun.

Post Flow Cooling Circuit
Protection to extend the life of consumables and the welding torch is enhanced by our post flow circuit that provides shielding gas after you release the trigger.
