I assume you are welding steel to steel so like jcc said 70 series is fine, but I actually prefer to use silicon bronze as it has a lower melting point and seems to require less total heat input which is always a good thing on sheetmetal.

It has a little "give" which helps prevent the sheet metal from cracking at the weld. If the results don't match the theory, change the theory.
