How to Use WelderData
Use WelderData as a repair workflow system: start from the symptom, confirm evidence, then move to the relevant board, chip or component reference.
Start from the symptom, not from the document
WelderData is organized as a repair workflow database. The fastest path is to start with the visible fault, identify the board or component layer, then open the related service reference.
1. Start with a faultNo output, no HF, protection light, breaker trip, no wire feed, weak loaded current.
2. Match the machine familyZX7, NBC, LGK, CT-312, WSM, WSE and other welder families.
3. Open the board referenceControl boards, driver boards, HF boards, feedback connectors and power boards.
4. Confirm component evidenceIGBT, rectifier bridge, 20040 diode, Hall sensor, SSR, capacitors and varistors.
How to read a diagnostic page
- Quick Answer gives the first likely directions and what not to replace first.
- Use this page / Do not use this page prevents applying the wrong workflow to the wrong symptom.
- Diagnostic Panel is a repair route, not just a drawing.
- Evidence table separates normal evidence, abnormal evidence and next check.
- Next diagnostic step moves the user to the related board, chip or component reference.
What WelderData is building
A structured welding-machine repair database: symptom routes, machine pages, board references, component records and repair cases connected by internal diagnostic paths.
