Build a Practical Welding Machine Repair Library
Instead of storing raw PDFs only, WelderData organizes welding machine information into searchable model pages, fault pages, board pages, component pages, and repair notes.
Welder Repair Guides
Troubleshooting pages for common welding machine faults such as no arc, no output, fan running but no welding, weak arc, unstable current, and high-frequency start failure.
View repair guides →Circuit Board Database
Structured information for high-frequency boards, main control boards, driver boards, power boards, arc-start boards, inverter boards, and wire feeder control boards.
Browse boards →Component Database
Notes for common welder repair components including UC3845, SG3525, LM358, optocouplers, IGBT modules, MOSFET drivers, rectifier bridges, and relays.
Explore components →Welder Model Pages
Model-based pages for TIG welders, MIG welders, MMA welders, plasma cutters, multi-process welders, and industrial welding power sources.
Browse welder models →Manuals & Diagrams
Organized indexes for service manuals, user manuals, schematic diagrams, wiring diagrams, PCB references, and repair documentation.
Find manuals →Fault Diagnosis Notes
Practical diagnostic information including symptoms, possible causes, test points, related boards, likely failed components, and repair direction.
Read diagnosis notes →What WelderData Will Cover
