Everyone who says to not run a bead is correct. Hope you are using a mig welder with sheilding gas, so much easier to clean up. A 110 V. with shielded wire is good also, be sure to wear your safety glasses when you hit the slag with your grinder. Skip weld is what you use, and until you are competely tacked up, spot abot 3" apart then "skip" around with 1/2" welds until you get it stitched completely. You can get your metal to pull tight by applying a cool damp cloth immediately after you finish your weld. If you ard using a stick, a cooler weld can be achieved by "pulling" the rod away from the work slightly after you strike your arc. I use that method on 20 gauge and lighter, and hold heat to 2 seconds or less. works well with cold galvenized, too.
