LGK-60: 60A IGBT Inverter Air Plasma Cutter — Portable Plasma Cutting Machine
LGK-60
60A Air Plasma Cutter
Part of the Plasma Cutters product line. Designed and manufactured in Qingdao, China with IGBT inverter technology for reliable industrial performance. CE certified for global export.
Typical Applications: 15mm clean cut, sheet metal, HVAC
LGK-60 Air Plasma Cutter
The LGK-60 is a 60A IGBT inverter air plasma cutter engineered for light to medium fabrication tasks where portability and clean cut quality are paramount. Operating on standard 220V single-phase power, this compact 8 kg unit uses compressed air as the plasma gas to deliver a quality cut of up to 15 mm on mild steel, with a maximum severance capacity of 25 mm. An optional built-in air compressor makes the LGK-60 truly self-contained for mobile repair crews, HVAC installers, and workshops without a dedicated compressed air supply.
Built around a high-frequency IGBT inverter power stage, the LGK-60 achieves a 60% duty cycle at rated current (60A / 104V), ensuring consistent arc stability during continuous CNC cutting operations. The high-frequency pilot arc allows the torch to cut through painted, rusted, or expanded metal without pre-cleaning, while the front-panel digital display and amperage control knob let operators dial in the exact cutting current for different material thicknesses. A standard CNC interface port with arc-on and divided-voltage output signals is included for seamless integration with gantry and table cutting systems.

Why Choose the LGK-60
Single-Phase 220V Operation
Plugs into standard household and light-industrial outlets — no three-phase power required. Ideal for mobile service trucks, home workshops, and rural job sites with limited electrical infrastructure.
Ultra-Portable at 8 kg
Among the lightest 60A plasma cutters on the market. A reinforced top carry handle and compact footprint make it effortless to transport between job sites or store when not in use.
Optional Built-in Air Compressor
The LGK-60B variant integrates a compact air compressor directly into the chassis. No external air supply, hoses, or fittings needed — unbox, plug in, and start cutting within minutes.
IGBT Inverter with HF Pilot Arc
Third-generation IGBT modules combined with a high-frequency pilot arc ignition system ensure instant arc start on every trigger pull — even on painted, rusty, or expanded metal surfaces. Automatic post-flow cooling extends consumable life.
