tack welding vs full bead

[kamaroman68]

Alright guys I have another question for you. Going to be mig welding thick metal to a thinner metal roughly 1/8 to 1/16. The 1/8" material being 304 ss and the 1/16th being plain old steel. I know you need to use the higher setting on the welder for the 1/8 ss. I am worried about burning through the 1/16th steel while trying to run a full bead. This is what I would call a structual part ( basically I am modifying a 68 camaro rocker panel). Could I just make a series of tack welds and go back and forth until all of the tacks are connected. Or would it be better to tack in place and run small beads roughly 1/2" to 1" long again with the chance of burn through. Thanks guys.
