UL or other NRTL listing of Vulcan Omnipro 220 multi-process welder
I received a Harbor Freight catalog in the mail and saw a Vulcan Omnipro 220 multi-process welder advertised. I did a web search for that welder to see what US regulatory agency or testing lab approval it has. I haven't turned up anything so far.

Stephen has said that the NRTL label would be on the welder and not mentioned in the manual. My bet would be that a NRTL certification would be a feature that costs the manufacturer money and that if such a certification existed, the manufacturer would trumpet it in the sales literature. I wonder if any of the multiple reviewers of this product are aware of any NRTL certification label?
I wonder if there is a way to query the NRTL labs individually to see if they have certified a product?
I wonder if there is any third party assessment of welder duty cycle?
