Review Methodology

Welder Guru does not publish fabricated hands-on tests. Here’s how we actually research and describe the categories you read about on the site.

Sources we use

• Manufacturer documentation — Miller, Lincoln, ESAB, Hobart, Eastwood, Forney, YesWelder, Vulcan, and others publish duty-cycle, amperage, voltage, and feature data. We read those.
• Industry safety bodies — OSHA welding fume and arc-hazard guidance, AWS safety publications, NIOSH ventilation recommendations.
• Publicly available welder educator content — long-form videos and articles from welding schools and instructor channels covering process selection, technique, and machine setup.
• General experience welding mild steel, stainless, and aluminum in home and small-shop contexts.

What we publish

Category-level guidance: “120V MIG welders typically do X well and struggle with Y. Verify Z in the manual before buying.” Specs we cite are presented as a range or category descriptor, not as a manufacturer datasheet. Our calculators output educational estimates with a clear reminder to verify in the welder’s chart and manual.

What we don’t publish

• Fabricated hands-on test data, dyno-style amperage readings, or pseudo-objective scoring rubrics.
• Fake star ratings, fake prices, or invented user-review summaries.
• Structural-weld, pressure-vessel, or critical-load welding instruction.
• Anything that downplays PPE, ventilation, or electrical safety.

How we link to Amazon

Every recommendation links to an Amazon search for the category — not a specific ASIN — so you see the current options, prices, and reviews. We never publish a single ASIN “Editor’s Choice” pretending to be a verdict.
