Which welder
Outlet voltage, breaker amperage, metal, thickness, and process. Results use published ratings. A line says when a figure was missing and was not scored.
How a pass is decided
- Voltage passes when the cited input includes that outlet class. 230 V and 208–240 V count as the 240 V choice. 460 V and 575 V do not.
- If the sheet names a breaker size, the check uses the largest such row that is not above the breaker you typed. Input current on that row still has to fit.
- If the sheet only prints input current at rated output, a breaker smaller than that current fails. A larger breaker is a warning, because a draw is not a recommended breaker.
- Process has to be named. Aluminum on TIG passes only when the page names aluminum. DC TIG that never names aluminum fails that metal.
- Thickness uses a printed inch maximum. A single-pass figure with no multi-pass maximum is a warning when you go past it, not a fail. Gauge-only ranges are not converted.
Does a 230 V rating count as a 240 V outlet?
Yes. The tool treats a published 208–240 V, 230 V, or 240 V input as the 240 V outlet choice, and it says so on the result. 460 V and 575 V do not match either household choice. 120 V, 115 V, and 110 V match the 120 V choice.
Is input current the breaker size?
No. Many sheets print amperes at rated output, which is a draw, and do not print a recommended breaker. If the draw is larger than the breaker you type, that check fails. If the draw fits and no breaker size is printed, the check is a warning, not a pass. A pass requires a breaker size the manufacturer actually printed, such as Hobart’s 15 A and 20 A rows on the Handler 210i.
What happens when thickness is a single-pass figure?
If the page says “single pass” and also says thicker material is possible without printing a second maximum, a thicker job is a warning. If the page prints a maximum and does not call it single-pass only, a thicker job fails.
Why can aluminum fail on a TIG welder?
Aluminum passes only when the cited page names aluminum. DC TIG that does not name aluminum fails that metal. The tool does not treat “TIG” alone as an aluminum process.
