Jersey,
I had bororrowed The Miller and just started using it. I am not very good at laying a beed but with body work it's mostly welding dots. If you weld too much in one area the metal deforms. So I just make a bunch of dots about two inches apart along the length and then go back and add more in the middle. Works weel and I don't deform the metal. I saw an episode of Rides with RAD Rods and that dude was using a TIg and he layed down a weld that looked like a machine did it! That kinda welding takes practice, practice and more practice. I ahve also found that folks are very touchy about their welds, it's not a good thing to dis someones welding ability. They get a bit PO'd about it.
I don't mind someone telling me that mine are not pretty, I know I suck welding!
