i try to weld my stainless manifold with a 110 mig welder. it doesn't work at all. bought the welder for nothing. i ended up paying this guy $60 to weld my manifold. i spend $600 on the damn welder too. i guess i can use it to weld my intercooler pipings. i have pic of the manifold if u guys wanna see it. show me how to post up the pic. i just need to cut weld the t3 flange in it. phanmy11@netscape.net

 

how many amps is your welder? You need SERIOUS amounts of power to weld stainless

 

you can post pics by going to www.pichold.com , then after you upload click on the icon next to yaBB and paste that onto your post. questions? PM me, glad to help.

 

I don't know about stainless, but I welded all my IC piping with a 85amp gasless campell-haus welder and it worked pretty damn good...

I'm going to get a gas optional welder from harbor freight, everyone told me the POS gasless welder prob. wouldn't cut it, but it worked just fine.

If the going get really tuff, I can drag it to the shop at work, them have all miller stuff. the Miller mig is like 240amps ( or close ), and has two guns, one for alum. and one for steel/iron. But not even the $2500++++ welder could help my lack of welding skill and my IC looked like crap, and I had to use JB weld to seal all the leaks...

 

What shielding gas were you using to weld the stainless steel? Did you know that it takes argon gas to create a zero oxygen atmosphere for perfect welds?

And yes, more current is needed to penetrate.

 

I too have welded my stainless manifold (SS autocrap) with a 110 MIG and it welded fine. It's held up fine so i know my welds are strong.

 

i got a lincoln welder. is rated at 135 amp with 25 amp output 110v. i use 100% argon gas. i set it at 15 psi at the gas regulator. i can weld stain by using flux core, but the manifold will crack in a month. this is the second manifold i'm making. i don't want it to crack this time. i'm gonna go look at the tig welder tomorrow. the guy want $1,100 for it. i will try to get the pic of asap

 

It really is about trial and error with anything you weld.

If the place u got your ---- from will let you upgrade to a phat TIG for $400 extra, go for it! You really need a tig and a mig in any "professional" shop, but tigs are so great, and you can perform ARC welding duty on them.

 

hey man, you dont really need that much argon.. i run 5 pounds at the regulator, with probably the same welder as you have. most steel works fine for me up to 1/4" anyway
