LGK Air Plasma Cutter Machine Manufacturer

Air plasma cutting uses a jet of ionised gas (plasma) at extremely high temperature to melt and eject metal from a cut, producing fast, precise cuts on electrically conductive materials — including mild steel, stainless steel, aluminium, copper, and brass. Unlike oxyfuel cutting, plasma cutting works on all conductive metals and produces narrower kerf widths with less heat-affected zone. Paragweld's LGK air plasma cutter series is designed for workshops, fabrication shops, and on-site metal cutting applications requiring clean, efficient, and portable cutting capability.

The LGK series machines are built with IGBT inverter technology, delivering stable plasma arc output with lower energy consumption. They are compatible with standard compressed air supply, eliminating the need for specialised gases and making them ideal for site work and small-to-medium workshops.

frequently asked questions (FAQ)

Start with the thickest plate you cut regularly and the power supply available on site. Output current is the main guide: the Cut 40 is rated at 40 A, the Cut 60 at 20–60 A, and the LGK 100, 120, 160 and 200 go up to 100, 120, 160 and 200 A. Pick a model with headroom above your usual thickness so you cut at a steady speed, not at the limit of the machine.
The Cut 40 runs on a single-phase 220 V ±15% supply, so it suits small workshops and site work where three-phase power is not available. The Cut 60 and the LGK 100, 120, 160 and 200 need a three-phase 415 V, 50/60 Hz supply. Rated input power ranges from 4.8 kVA for the Cut 40 to 45 kVA for the LGK 200, so check your supply capacity before choosing a larger model.
The air must be clean, dry and at a steady pressure. The LGK 100 to 200 models are specified for 4.5–5.5 kgf/cm² at the machine. Moisture or oil in the air line shortens electrode and nozzle life and spoils cut quality, so fit a filter and water separator between the compressor and the cutter, and drain the compressor tank regularly. Size the compressor so the pressure holds during long cuts.
Duty cycle is how long a machine can cut at rated output in a 10-minute period before it needs to cool. The Cut 40 and Cut 60 are rated at 60%, which suits intermittent workshop cutting. The LGK 100 and LGK 120 are rated at 80%, and the LGK 160 and LGK 200 at 100%, all at 40°C ambient, so the larger machines are better suited to long production runs.
Yes. The LGK 100, 120, 160 and 200 are listed with a dross-free cutting thickness for CNC use of 12 mm, 16 mm, 18 mm and 22 mm respectively, so they suit mechanised cutting as well as hand work. They will cut thicker plate than this, but the edge may need cleaning afterwards. To confirm torch and controller compatibility with your table, please contact our team.
