Since a 30a 110v circuit is not normal (and I did not have any of them in my shop) I just wired up an adapter off one hot lead of my 220v outlet and good to go! My dad has been using his welder mainly for sheet metal work on his 40 Chevy, thus the reason as well for him running .023. I was used to welding a bit heavier metal and using .030. What I found is that the .023 tended to get stuck at the tip a bit and then would king inside the machine between the rollers and the beginning of the liner and create a rats nest. As soon as I switched to .030, never had that issue again. Mentioned it to my dad and gave him a roll of the .030 to play with in his new welder and he found it runs smoother as well. You may need the .023 for thin sheet metal work if you can't get the .030 to work, I have not messed with that much thin stuff but will be doing so in the near future! Just my 2 cents worth!
