That certainly happened.
These little power supplies are often loosely referred to as transformers. That certainly messed up a lot of people's understanding! My apologies.
On the other hand, I was able to run the Ready Welder on my welding machine's CV setting of about 20 VDC, and it ran great! Like someone said before, the wire speed control is loose, and an unanticipated bump can really crank up the wire speed without the operator realizing it.
The wire speed control also sits very close where my right thumb stays while I'm using it. This was probably meant to be a feature, but with my welding gloves on, I think that thumb was responsible for many of the bad wire speed settings.
Also, the unit is always electrically hot. By this, I mean even the nozzle arcs against the metal - and without the trigger being pressed!
Finally, I'm running flux core wire at the moment, so I don't really even need a nozzle. However, the tip and gas diffuser both seem to be integrated into the nozzle. In the Ready Welder store, they show a Nozzle Insulator which may be for flux core use, but (like everything else in their online store) it does not have any description of what it is for.
But, I got the unit to work for me, and I didn't even need the adapter with my welding machine set to CV.
Thanks every> By the way, ip2express, I think you introduced some confusion by
