LGK-100 Air Plasma Cutter

This model reference now uses cropped component diagrams with English labels instead of full-page source scans. Use it to identify the control path from panel mode to air system, torch connection and work clamp.

LGK-100 front panel crop: mode switches, status lamps, current knob and torch/work connectors.

LGK-100 rear panel crop: breaker, air filter/regulator, cooling fan and grounding area.

External connection crop: input power, compressor, work clamp, torch lead and gas/electric hose.

Torch consumables crop: shield cup, nozzle, swirl ring, electrode, torch body and cable/gas hose.

Field-use notes

Use air check mode before cutting to confirm air path and purge moisture.
LGK-100 uses non-contact torch start; keep the nozzle roughly 3–5 mm from the workpiece for starting.
Poor consumable alignment can cause weak arc, poor cut quality or nozzle damage.
Moisture in the air filter affects arc start and cutting quality.
