I purchased myself a welder to weld in a small section of my frame rail to weld in a new subframe bolt (long story). I'm wondering if the weld is supposed to go all the way thru the metal or not. I've been practicing on 1/8" steel and cannot get the bead to go all the way thru. It's a cheapo 90 amp. Also, is there any difference between a stringer bead or like a weave? I'm a lot better with a stringer, and the weld is a lot cleaner is why I ask vs me doing a weave pattern.
