Spectrum® 125C
1/8" mild steel cutting capacity and a built-in heavy-duty compressor makes this an out-of-the-box ready plasma cutting system.
Rated Cutting Capacity
Constant Output Cutting Power
The constant current design offers a consistent 12 amp cutting arc for continuous quality cutting up to 1/8 in. steel.
Portable for Your Applications
Spectrum® 125C comes complete with built-in heavy-duty compressor and weighs only 31 lb, offering the operator a high level of portability and convenience.
Built-In, Heavy-Duty Industrial Piston-Driven Compressor
Built-in, heavy-duty industrial piston-driven compressor provides long life and superior airflow.
LVC™ Line Voltage Compensation
provides peak performance power under variable conditions (98 to 132 volts) for steady cuts and cleaner ending cuts. See How.
Auto-Refire™ Technology
provides ultimate customer convenience by automatically controlling the pilot arc when cutting expanded metal or multiple pieces of metal. The pilot arc will switch in and out as fast as needed when cutting expanded metal and provides maximum power for cutting thicker metal—all automatically! No need for manual re-triggering which reduces user hand fatigue.
Can Be Powered by Miller Engine Driven Generators
Can be powered by any Miller engine drive with generator power output of 2 kW or more, such as the Bobcat, Trailblazer or equivalent competitive equipment.
