LGK-105AM Built-in Air Compressor Plasma Cutter

The LGK-105AM integrates welding and cutting with a built-in air compressor, forming a mobile plasma cutting workstation. The operator selects either the internal air source or an external supply, so the same machine works on site and in the workshop. A built-in 1500 W high-pressure compressor removes the need for external compressed air, which is what makes unattended outdoor cutting possible. A four-stage low-speed motor drives the compressor: at equal air output the piston lasts longer, and the unit runs more steadily and more quietly. The compressor sits on anti-vibration mounts that absorb the shock of operation and transport, reducing the risk of internal components working loose, cutting noise and extending compressor life. A high-quality pressure-regulating filter gives fine filtration and stable, reliable regulation. Mature current ripple control technology produces flat, clean cut faces. The main circuit uses two large 1000 µF / 400 V filter capacitors for strong resistance to supply fluctuation, so the machine also runs steadily on generator power. Protection is comprehensive: over-temperature protection, compressor phase-loss protection, and over-voltage / under-voltage protection. Applications Manual cutting of carbon steel, alloy steel and non-ferrous metals. Widely used for pipelines, steel structures and power-plant installation, outdoor electromechanical equipment repair, metal demolition and recycling, and other non-fixed, frequently relocated sites. Not recommended for fixed indoor installations.
