WelderData Terms of Use
WelderData provides technical reference material for qualified welding-machine repair technicians. Use of the site means you accept the limitations, safety requirements and permitted-use conditions below.
Technical-reference scope
Content is provided for technical education, diagnostic organization and repair reference. It is not a substitute for the original manufacturer service manual, local electrical regulations, workplace procedures or competent hands-on judgment.
Qualified use and safety
Welding machines may contain lethal mains voltage, charged DC-bus capacitors, high-frequency ignition circuits and high-current power stages. Only qualified personnel should perform energized measurements or board-level repair. Follow the WelderData safety notice before using any workflow.
No warranty
Machine revisions, component substitutions, undocumented board changes and prior repairs can make any reference incomplete for a specific unit. WelderData does not guarantee that a measurement, component designation or repair route applies to every board revision.
Permitted use
You may use the site for personal, educational and professional diagnostic reference. Do not republish substantial portions of the database, remove attribution from WelderData diagrams, automate bulk copying, or present the material as an official manufacturer service publication.
External sources and trademarks
Product names and trademarks belong to their respective owners. References to a manufacturer or model identify equipment compatibility and do not imply endorsement or affiliation.
Changes and contact
These terms may be updated as the database and tools evolve. For corrections, attribution questions or removal requests, use the contact page.
