WSE AC/DC Pulse TIG Welder Repair Hub
A model-level hub for WSE AC/DC TIG welders, connecting control panel, secondary inverter and TIG sequence diagnostics.
Quick Answer
The WSE AC/DC TIG hub adds secondary inverter and AC/DC mode logic to the normal TIG gas/HF/current route.
- If DC output works but AC output is missing, start with AC/DC mode command and secondary inverter/driver evidence.
- If both AC and DC are missing, diagnose primary output before secondary inverter.
- Panel pulse and balance settings should be checked before replacing secondary inverter devices.

WSE symptom routing
| Symptom | First layer | Next page |
|---|---|---|
| DC works, AC missing | AC/DC panel command and secondary inverter | AC output missing route |
| Pulse missing | Panel command/control-board processing | Current-control panel faults |
| Balance abnormal | Balance command or secondary switching | WSE control panel + secondary board |
| No gas/HF timing | Generic TIG sequence | TIG timing route |
