CUT-100B
CUT-100B combines three-phase 380V input, built-in and external air source compatibility, plasma cutting plus manual arc welding, and a higher-output inverter platform designed for thicker iron, stainless steel, and aluminum plate cutting in fabrication shops, field work, and maintenance environments.
An all-in-one inverter plasma cutting and MMA platform with integrated air source support, optional external compressed air connection, and stronger three-phase output for heavier cutting and repair work.
CUT-100B Technical Specifications
Core electrical data, air source configuration, and cutting capability for the CUT-100B built-in air compressor plasma arc cutting machine.
Higher-output built-in compressor plasma system for thicker plate cutting and heavier fabrication work.
CUT-100B is positioned for users who want the convenience of an integrated air source but need more cutting reserve than the smaller portable model, together with plasma cutting and MMA welding flexibility on one inverter platform.
Dual air supply and dual-function cut + weld capability
The machine supports both the built-in air compressor and external compressed air source while combining plasma cutting and MMA welding in one machine, making it practical for workshop fabrication, repair, and maintenance tasks.
All-in-one structure reduces setup dependence in workshop and field use
Power source, air compressor, and cutting system are integrated into one compact machine body, helping reduce accessory dependence and making the unit easier to deploy for installation, maintenance, and repair work.
20 kHz IGBT inverter technology for compact and stable arc performance
The power section uses a 20 kHz IGBT inverter platform to support stable arc characteristics, efficient operation, and a more compact machine body than conventional transformer-based designs.
Air-cooled construction with 60% duty cycle at 25°C
The specification table lists air cooling for both power source and torch, 60% duty cycle at 25°C, Class F insulation, and IP21S enclosure protection for regular fabrication and maintenance work.
Compressed-air cutting performance centered on the stated carbon steel range
The table specifies compressed air as the plasma gas, 25 mm quality cutting capacity on carbon steel, and maximum cutting thickness up to 40 mm with the built-in air source or 45 mm with an external air source.
