As you turn up your amps it doesnt turn up your wire speed? They advertise that it does, and I've heard from other people they do.

I suppose I have not noticed that... but I have a speed control so I'm not that it matters anyway. IF it did turn up the speed then I could just turn it back down.

Nice Exhaust, the fencepost wont rust due to it being galvanized, whoever said that is a dummie.


Galvanized steel DOES rust eventually...and being the welding points have now exposed the steel it will rust at those points faster.

Galvanization is just a coating of Zinc on the steel. Its a preventative not a cure.

We all agree to that... in fact Logan didn't claim it wouldn't rust... he said it WOULD rust.

Alright. I must have miss read that...

"Logan: you shouldnt weld galvanized, bla bla bla.

This sentence indicates that someone stated that a galvanized pipe wont rust.

I could not find the person who made that incorrect statement, so i went a different direction with trying to understand his statement.

In this case he is trying to contradict someone who said the Galvanized pipe WOULD rust, which is correct, and calling someone a dummie for stating the correct information. Hence my post...

I apologize if im incorrect in thinking Logan was incorrect...

You are correct, I know exactly what the galvanization process is, I was just trying to state that it has less chance of rusting than mild steel, not that its rust proof. Some stainless steels rust even, such as 400 series.
