Last night I was welding up some cuts on one of the doors of my Chevroloy project. I kept occasionally burning through the metal. I have some questions about the settings I was using on my welder.
I'm using a Lincoln Weldpak 100 with MIG gas conversion.
Because the metal is fairly thin (18 gauge?) I was using it on the "A" setting ('A' is for the thinnest metal, 'D' is for the thickest.) I had my gas pressure set at around 16-17 pounds. I had my wire speed set at about 2-3.
I thought (and I may be wrong) that turning up the pressure on the gas (went to about 19psi) would help prevent burn-through because it would make alittle 'colder' weld. Is that right? I'm not sure if seemed to help or not.
A few minutes later I turned my wire speed up to 4-5 and I tried to move a little faster. That seems to have also helped some.
I know because the metal is so thin that I shouldn't weld more than around one inch at a time. I tried to stagger the welds out to prevent that.
Any suggestions?
