Fault index

LGK Plasma Cutter Fault Index

A practical index connecting LGK60L and LGK100L plasma-cutter symptoms to fault routes, board references and control-power evidence.

Quick Answer

Use this index when the machine is an LGK plasma cutter or a similar plasma-cutter platform and the first symptom is known.

LGK60L pages cover fan, gas, O.C light and HF/gas control-board evidence.
LGK100L pages cover no response, display, protection, no output, breaker trip, IGBT and weak current.
Control-power rail pages connect symptoms across LGK60L and LGK100L.
