Can anyone recommend some references for a beginning MIG welder? I did OK in the class with @JoeN looking over my shoulder, but working on my own I’m having a hard time getting good penetration. I’m not sure if I’m struggling with technique or machine setup.
I found a reference sheet (don’t remember if it was Lincoln or Miller) that said to use 16V for 16ga steel, but at that power I was just leaving globs I could knock off with a hammer. Around 20V I got burn-through. My welds seemed to be welding around 18V, but it never sounded right.
I’d love a picture/video troubleshooting guide – something the effect of “if this is what you’re seeing, here’s what to change” would be super-helpful. It’s also possible I need more basic tutorial with different materials. I’m definitely open to suggestions.
