I have a question. I just bought a 175 amp mig machine. I am using the flux wire while getting familiar with welding. I have never welded anything before last friday.
What relationship does wire speed have with heat and penetration? It seems that I can weld thick things (a 5/16 plate to bed frame angle iron) ok. I tend to blow through when trying with some thinner tubing. If I turn down the current, I am concerned that I wont get the penetration on the thicker metal. I have tried the second and third setting, not the first. This is not race legal stuff, just some square stock from HD and some metal closet rod. Which looks like blue line tubing from the inside. I know that race tube is thicker than this, but I dont want to blow through the thin metal on the stang when I try to do my inboard coilover conversion.
If I get good enough, I want to try to fab some stuff on my car. i know that I have a while to go, but I figure I have to start somewhere.
