Mike, so many of the welders made nowadays do in fact have sensing circuitry to accommodate different power schemes. Sounds to me as if this may be the case. But, there should be some documentation in the unit. If not, type in the brand and model no. to Google to get cross reference to brands and then to discussions of same.
