That answers alot of questions! thanks for the tech! so, when it comes to tacking your pieces in, and using a mig, how do you keep from blowing holes? I have my mig set on the lowest setting and my gas at 30 and I still blow holes. does the fact that the metal is older have anything to do with it? If I don't blow hole then sometimes my welds just sit on the top and don't penetrate at all. I know it has alot to do with practice and settings, but damn it starts to get frustrating after awhile.
