Corrections, model suggestions and collaboration

Contact WelderData

Use this page to report a technical correction, suggest a welding machine model, point out a broken link, or discuss structured welding-machine repair data. WelderData is a technical reference project, not an emergency repair service.

What to contact us about

Good feedback should include the page URL, machine model, visible symptom, board or connector label, and the correction or evidence you want reviewed.

Correction

Report a page correction

Wrong connector labels, missing safety notes, unclear diagnostic order, or outdated page relationships.

Model

Suggest a machine model

Suggest a welder, plasma cutter, board family, chip, component or repair workflow to add.

Data

Submit repair data feedback

Share structured notes about symptoms, measurements, board evidence or real repair outcomes.

Business

Business or collaboration inquiry

Discuss technical collaboration, repair-data partnerships, sponsorship or product opportunities.

No emergency repair support

WelderData does not provide emergency troubleshooting, live repair supervision, certification, or safety approval for a machine. If a welder has smoke, fire damage, severe PCB burning, unknown modifications, repeated breaker trips, or exposed high-voltage wiring, stop repair and use qualified local service.

Report a correction

Send the exact page URL.Example: a model page, fault page, diagnostic workflow, board reference, component page, chip page or repair case.

Describe what is wrong.Be specific: wrong connector label, wrong voltage wording, unclear board relationship, missing cross-link, broken URL, or a section that could mislead repair order.

Explain the evidence.If possible, include the machine model, board marking, connector label, visible symptom and measurement condition.

Suggest a model, board or topic

WelderData is strongest when new pages connect to actual repair use. Suggestions are most useful when they describe what a technician would search for or measure.

Suggest a ModelKnown welding machine model, brand, series, control panel or machine family. Suggest a BoardBoard stack, connector reference, HF board, control board or power board. Suggest a Diagnostic WorkflowVisible symptom plus step-by-step measurement route. Suggest a ComponentIGBT, rectifier bridge, output diode, Hall sensor, relay or gas solenoid. Suggest a ChipPWM controller, optocoupler, op-amp, driver IC or shutdown path. Suggest a Repair CaseReal symptom, measured evidence, misdiagnosis trap and final repair lesson.

Useful repair data format

Machine and board identity.Model name, front-panel label, board marking, connector labels and process type: MMA, TIG, MIG, plasma or combo.

Visible symptom.Examples: no output, no gas, no HF, protection light, breaker trip, weak current, wire feeds continuously, current cannot adjust.

Measured evidence and repair outcome.Only include measurements taken safely by qualified people. Add what was replaced, what changed, and what did not fix the machine.

Business and collaboration

WelderData may consider collaboration around structured repair data, machine-model coverage, board references, technical content, repair workflow products, database partnerships or diagnostic tools.
