CUT-80B
CUT-80B combines 220V/380V dual power input, built-in and external air source compatibility, plasma cutting plus manual arc welding, and an inverter body designed for carbon steel, stainless steel, and aluminum plate cutting in workshop, installation, and repair work.
An all-in-one inverter plasma cutting and MMA platform with dual-power input, integrated air source support, and optional external compressed air connection for cutting and repair work without depending on a separate compressor.
CUT-80B Technical Specifications
Core electrical data, air source configuration, and cutting capability for the CUT-80B built-in air compressor plasma arc cutting machine.
Dual power, dual air supply, and integrated cut + weld capability for mobile industrial work.
CUT-80B is positioned as a field-ready inverter plasma machine for users who want an integrated built-in air source, optional external air supply, and the flexibility to switch between plasma cutting and manual arc welding on one compact platform.
Dual power input and dual air source flexibility in one machine
The CUT-80B platform supports 220V and 380V input while allowing both built-in air source operation and external compressed air connection, making it easier to adapt between workshop and field environments.
Plasma cutting and manual arc welding combined for field construction and repair
One-machine dual-use configuration combines plasma cutting and MMA welding, making the machine practical for installation work, maintenance, repair, and service tasks where combined cut-and-weld capability matters.
20 kHz IGBT inverter platform for compact and stable output
The power section uses a 20 kHz IGBT inverter platform to support stable arc characteristics, efficient operation, and continuously adjustable output in a more compact machine body.
Air-cooled construction with 60% duty cycle for practical site use
The specification table lists air cooling for both power source and torch, a 60% duty cycle, Class F insulation, and IP21S enclosure protection for routine workshop and field work.
Compressed-air cutting performance centered on the stated carbon steel range
The table specifies compressed air as the plasma gas, 12 mm quality cutting capacity on carbon steel, and maximum cutting thickness up to 20 mm with the built-in air source or 25 mm with an external air source.
