Miller Spectrum 125C (MIL 907149)

Mild Steel
Cutting Capacity


12 ga (2.0 mm) at 35 IPM

1/8 in (3.2 mm) at 10 IPM
Not to scale.

Built-in, heavy-duty industrial piston-driven compressor provides long life and superior airflow.

Solid-state, constant-current design offers consistent 12 amp cutting arc for continuous quality cutting up to 3/16 in steel in steel.

Electronic Pilot Arc Controller automatically controls the pilot circuit to provide expanded metal cutting ability without having to re-trigger the torch, increasing productivity and extending tip life.

LVC line voltage compensation provides peak performance power under variable conditions (98 to 132 volts) for steady cuts and cleaner ending cuts.

Can be powered by any Miller engine drive with generator power (e.g. Bobcat) or equivalent competitive equipment. See Spec Sheet for kW requirements.

35% duty cycle is tested at 40° C (104° F) to give you the cutting power whenever you need it.

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.
