This page is the fastest complaint-to-action entry point for WeldKing. It tells a technician what to open first from only the incoming complaint.
| Incoming complaint | Likely family or branch | First guide | First packet or workflow | First bench sheet or proof step | First local files |

MigSonic252S+SS20 guide | MigSonic252S+SS20 job packet | prove the power source itself first by checking readouts, jog or purge behavior, and idle gas state, then separate feeder-package and spool-gun connection faults before feeder blame | MigSonic252S_owner_manual.pdf, workbook sheet MigSonic252S |
| external-air no-start, bad hose or valve routing, or guide-hardware complaints on a CB50 plasma | hose, valve, CB50 torch, and guide branch on CUT40 |
CUT40 guide | CUT40 job packet | prove dry external air under flow, a fresh CB50 front end, a clean clamp path, and freehand cut behavior before blaming the control board or any guide hardware | Cut40_owner_manual.pdf, workbook sheet coolcut40air |

| rough arc with ripple feel, or feed direction wrong after board work on a mid MAG machine | ripple, gas-solenoid, and post-service direction branch on MAG251 |
MAG251 guide | MAG251 job packet | prove plain-steel MIG first, check for about 1 VAC versus 6 to 7 VAC ripple behavior, and verify correct feed direction after service before deeper teardown |
mag251manualweb.pdf, workbook sheet MAG251 |
| wire creeps after stop, sparks appear at the wire tip with no trigger, or spool-gun mode will not weld | crater-fill, discharge-path, and spool-gun-voltage branch on MAG255 |
