Re: MIG welding stainless steel.

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...

Re: MIG welding stainless steel.

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...

Re: MIG welding stainless steel.

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.

Re: MIG welding stainless steel.

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?

Re: MIG welding stainless steel.

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...

Re: MIG welding stainless steel.

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...
