LGK-120IGBT
LGK-120IGBT is a higher-output industrial plasma cutting system designed for three-phase 380V workshops that need 120A output, 100% duty cycle at 40°C, and stronger plate-cutting reserve for fabrication, maintenance, and production tasks.
A production-ready external-air plasma platform for heavier workshop cutting, plant maintenance, and industrial fabrication teams that need more current, more thickness range, and continuous-duty reliability.
LGK-120IGBT Technical Specifications
Published electrical, cutting, air-pressure, and dimensional data for the LGK-120IGBT plasma cutting system.
Higher-output IGBT plasma cutting for heavier fabrication demand and longer daily operating cycles.
LGK-120IGBT is positioned for users who need a clearer step up in thickness capacity and duty performance over compact plasma systems, while still keeping an air-cooled external-air setup and practical CNC-ready voltage outputs.
Continuous-duty performance for demanding workshop and production use
The published table lists 100% duty cycle at 40°C, making this model a stronger fit for longer operating periods and heavier industrial work routines.
120A output with substantial carbon-steel cutting reserve
Official data gives a 30-120 output-current range, 0.3-25 cutting thickness, and 45 handheld severance thickness on carbon steel for heavier workshop and production applications.
IGBT inverter stability with practical voltage-output options for system integration
The IGBT power platform and listed 1:1, 1:20, 1:50, and 1:100 arc-voltage output ratios support stable cutting performance and easier integration into manual or CNC-related operating environments.
Standard external air supply with air-cooled machine construction
The machine is specified for 0.4-0.6 MPa gas supply pressure and air cooling, helping simplify maintenance and installation in shops with reliable compressed-air service.
Designed for users who need more output without moving into extreme heavy-duty equipment
Its published 52 kg machine weight and 695×320×580 mm footprint keep the system manageable while still offering a meaningful upgrade in current and cut capacity.
Standard product positioning
- Model: LGK-120IGBT
- Type: IGBT inverter plasma cutting system
