mate its easier to NOT use the correct gas. I find that stainshield is a fair bit hotter and on thinwall its a little hard.

also if you need tube and bends etc go to midway metals in yatla. about half the cost of anywhere else.

MIG and Stainless steel comes up good, you should use stainless steel wire though.

doesn't splatter as much as mild steel thats for either wire.

staining

Post by lukes4x4 »

Once you weld it to remove the stains buy some pickling paste. put it on wait a few minutes and wipe it off. might have to do it a couple of times, but will get rid of ugly brown stains.
