Don't feel bad, all welders have to start somewhere. I thought I knew a thing or 2 about welding until I started working for my current employer, all our MIG's are set up to run 300+ amps and between 30 to 32 volts which means a lot of .045" wire, very hot very fast. The first time I pulled the trigger on one of those monsters just about scared the daylights out of me and I realized I had a lot of learning to do.
