After a quik brush with a SS wire wheel sorry bout the poor pics using a camera phone.

Now for the Stainshield 69 heat is much more controllable with me being able to set my welder to setting 3. My welder is an old Uinimig 175 the amperage slection is a bacic large knob with clicking sections 1 through to 8. Very minimal spatter flatter bead and penetration it not over the top. Butt w...

I had a bit of a play around with the roll of 0.9mm of mystery stainless wire I have running a few beads on scrap and trying a few butt welds on some scrap tube. At first I tryed the Argosheild light, I found It very hard to control heat I can get a good bead but only on my welders lowest setting an...

Ok I finally got around to getting my hands on a bottle of stainshield 69 cost me $315 for a size G bottle as this is the only size they would supply it in. I was quoted $215 for stainshield 66 for the same size bottle.

Thanks Steve so this grade of Stainshield would be better?

For the non Australians wondering what Argosheild and Stainshield gas is.

Just noticed the Argosheild I have contains Oxygen. Introducing oxygen to the weld puddle would cause the weld to rust wouldn't it?

Ok spoke to one of the guys at the engineering place. His advice was just to use stainless wire he didn't specify exactly what type of wire though, and my bottle of Argoshield will be fine for what I want to achieve. If I wanted a much cleaner looking weld go for the Stainshield but he said if I wan...

Excellent thanks for all the info sounds like pure argon is not the way to go. Im getting some machine work done tomorrow at a place that builds alot of fuel tankers. I will pick there brains and maybe they will show me how they do it. And if all else fails I will get myself a bottle of stainshield ...

So its that simple Mike? 308 wire and stainshield for a good quality no rust weld. I did see that gas and thought being called stainshield and stainless is what its designed for, it would be the best gas I could get my hands on for what I want to achieve. Although its much different to tri mix. A fr...

Gary I can not even find any tri mix locally where do I find it and whats it cost? I have an account with BOC gas but nothing on there website seems to be close to tri mix. I have mig welded a few stainless exhausts on old junk cars with ER-70 seem to hold up ok but I am concerned with them cracking...

Ahh good to see a few of us on hear dont blame you guy's so much useful information better than anyone or anything I have come across before. So Im a bit of a noob when it comes to anything other than mild steel and working for a local scrappy now I have access to a huge variety of materials for nex...

Thanks Steve I have access to an unlimited supply of 316 and 304 tubing removed from industrial food processing equipment I am unsure on wall thickness exactly but is perfect for building my own custom exhaust systems My weling machine Uin Mig 175 about 8 year's old and is not an inverter type.

Hi just want to know what can be achieved in the way of MIG welding stainless steel tubing? And how it is achieved?
