im thinking about going ahead and buying a mig welder for my turbo project so i dont have to rely on other people anymore.
migs are way more affordable than tigs. has anyone done stainless steel with a mig. i assume it should work fine.
please post up experience with this. either good or bad.

 

found a lincoln 3200 hd with a co2 tank for 400.

 

you need wire for ss and shilding gas for ss otherwise it will rust where you weld thus being a shitay job but it will work.

 

get some stainless wire and trimix gas, co2 will work but trimix will work alot better.

 

trimix is just a different type of gas. or 3 types of gas.

 

it works alright, depends alot on the type of gas. tri mix is a bit easier to work with but straight argon is supposed to be less prone to reducing the SS ability to fight corrosion. id rather have a more solid weld and like .5% faster rust rate.

Stainless however never welded anywere near as easy for me as mild steel, that stuff just welds so nice with a mig. personally id say your better off being able to rely on yourself, get the welder. at least you can start the learning process and get some experiance.

 

ok so a friend of mine says that mig welders just dont penetrate as well.
and the welds wont last as long. as a tig welder will give you better quality
longer lasting welds. tigs are just so expensive. harder too, although coming
from oxy i think i would have a little heads up on it.

 

fluxcore works beautifully on stainless.

your friend is full of ----, he's probably never welded with either

 

^^ this man speaks the truth. Your friend is full of ----. I've welded a good amount of stainless with a GMAW machine, and the right gas makes the difference. I can get plenty of penetration with a MM350P.

 

so the right gas does it all. where do i get trimix.
