Just wondering if anyone out there had welding knowledge, been a while and don't have my books near.

will a portable mig welder weld a 1/8 to 1/4 inch thick stainless. I think that there are problems. I weld steel a lot and remember something quirky about stainless steel welding, temp or something.

any help or advice would be great

thanks
chris

You have to use staight argon not argon/co2 mix

You could probably get the 1/8 done easy enough with the portable you may be pushing it to get the 1/4 done with it depending on the size of the portable. If all else fails you could go with a stick welder if you want, you don't have to worry about buying a bottle of argon for a small project.

Thats what i thought. I didnt think i used argon the last time that i did a small job.

thanks for all the help, any other advice would be great.

I've been welding 1/8 mild steel with 100 amp Mig welder. I don't think that you can do anything thicker or stainless with that amperage.

BTW, I'm using flux core wire, so no gas.

in my opinion flux cores wire sucks. I would rather go with gas anytime. You get better welds. And they certianly are neater.

When appearance counts Tig is the way to go.
Flux core is ok and looks better if you run it along with a shielding gas. Not all wire is the same make sure it matches what you are welding or it will color differently when polished.

Also remember that your welds arent going to be stainless either, you'll want to protect the welds or they'll rust while the rest of the metal doesnt.

Stainless, when heated, will also make some funky gases. Make sure you do this outside or have really good ventilation.
