Yeah I got them from eBay , I’m sure they were sold from an actual welding company wholesaler , they have all the necessary badging etc. yeah I do know a few I will see if I can get an hours lesson. This piece wasn’t my actual test piece just so you know. Unfortunately test piece doesn’t look as nice. So with the test is it really down to me to be choosing the amps/volts or is that a preset thing by the inspector you have to abide by?
