Koji,

You are much better off going 98/2 for gas. There are just too many chances for porosity and possible cracking with 80/20 and SS. See if you can even go as far as renting the bottle AND gas from the supply company.

EDIT: 80/20 is just fine for Mild Steel, so you should have zero issues if just welding mild steel to mild steel.
