Stainless MIG wire

[Trollhole]

Yes I am a tard I typed it wrong.

I know it's expensive but is there any advantage to using stainless over the regular stuff?

What gas do you run with it. I'm thinking if it is just as strong as the other stuff an won't rust that is one less thing I will have to worry about rusting off.

I may be wrong but I think you can only use stainless wire to weld stainless.

tri mix(argon/helium/oxygen) would be the gas.
but what are you welding?
sounds like just black and you want ss filler just so the bead will not rust?
if so you're just wasting money. there is no advantage to using ss filler on blk steel.
1. it's nowhere near as strong a weld, if you're just joining blk.
2. once you mix the ss filler with the blk base metal....it will rust anyway.

Just to keep the conversation going adn the assumptions above, why wouldn't you just use copperweld or a weld through primer to reduce rusting at teh seams?

The strongest weld is going to be using the same filler as the base metal. Anything extra you introduce into the joint (weld through primer?, a different alloy filler, etc.) will weaken the weld.

If you are going to prime the piece just wait until you finish welding it.

Thanks everyone. This is good info. I'll stick with the tried and true.
