About
About WelderData
WelderData is a structured repair database for inverter welders, control boards, chips, circuits, faults and repair cases.
What WelderData is
WelderData is built as a technical index for board-level inverter welder repair. It is not a raw download site for manuals or schematic scans.
Core scope
- Chinese-made and OEM inverter welders.
- ZX7, ARC, MMA, TIG, NBC/NB MIG and LGK plasma cutter platforms.
- Control boards, auxiliary supplies, wire-feed boards, HF start boards and driver boards.
- Repair cases with symptoms, measurements, failed components and repair results.
Publishing principle
WelderData uses original summaries, simplified diagrams, diagnostic tables and rewritten repair-case records.
