stainless mig welding wire.

[v8ian]

Hi Chaps.
I have a stainless exhaust to modify on one of my projects, I am fairly certain I can get this done with my ESAB mig, I bought a 1kg drum of wire, set the welder to where I guessed the setting should be, and using a bit of ss wire, welded an acceptable bead, I said bit, because the drum the 1 kg came on has a small bore and my welder had a fixed large (2"ish) spigot that appears it cant be change with major unwanted surgery, does anybody know where I can get a 1kg drum of ss wire with a big bore. I'm not overly keen on buying a big drum as I only have about half a linear mtr to weld, any suggestions please,

Wind it onto your your mild steel roll and use it from there.

I think that will be the plan

And you won't need me to say keep the tension when spooling it from one to the other but I will say it anyway

And the SS wire is sprung, more like Piano wire than welding wire.

You need to use pure argon when welding stainless. Also you should change the liner and tip to a fresh one i.e. no rust/contamination

[Darkspeed]

Argon mix is fine and no need to change tips and liners.

Agreed, welded stainless with my mig with Argoshield and dirty tips.
Acceptable weld, no-where near as nice as tig of course.
