> You guys also have to remember that if you are using any cutting or grinding abrasive (CO wheel, cold saw, chop saw, grinder, etc) that has been used to cut mild steel you will embed cabon precipitates into the stainless before you even begin to weld. Once you get the pool going, those precipitates rise to the surface and the weld will rust regardless of proper gas coverage or back purge. Even using a regular steel wire brush can do it.

> Gas mixes discussed are all correct. If welding 321 or 625 adding a bit of helium is good(although expensive) and allows you to get good penetration with about 10-15% less amperage. Same with aluminum, there’s a gas mix called “aluma-shield” or similar. Very good for welding thick aluminum or castings(heads, blocks, 3/4"+ plate, etc)

oh damn! i didnt know u have to be “kosher” with saws and stuff. its like u have to have a different saw for different peice of metal.
