I recently purchased a Draper 70011 to learn both stick and tig welding. It supposedly has Dinse 35/50 sockets on it. I purchased a tig torch and picked up a Dinse plug for it but when I tried to plug it in it won’t tighten. I noticed that the stick torch that came with the welder has a Dinse connector where the notch is flush with the end of the connector. It’s almost as if the connector has been ground down. Is there a slightly different standard I should be looking for?
