Postby billb » Tue Apr 18, 2017 11:49 am

Hey Guys

Long time lurker first time poster.
I have a kitchen hood to weld that is 18 guage 430 stainless
I never attempted to mig 430 before
I am having a hard time finding a small spool of 430
Also it looks like i need trimix for a shielding gas

Any help would be appreciated
Thanks'

For the love of everything, TIG it. Don't MIG it.

Better question...What the hell is 340 stainless or 430 stainless or 034 stainless or 403 stainless and what wire do we use?

We used to use 347 ss on gas turbine assemblies that would see heat. Exhaust duct and associated items. I don't know if that was the classification of the wire and the base metal or just the wire.
