Welding SFC's
Stick rod gets hotter, make sure you pull up the carpet above any place being welded. That stuffing under the carpet is flammable and guys have caught their cars on fire by welding subframes before.
Think safety first!
Be sure you prep the areas to be welded by using a buffing wheel to get the paint/primer off. Makes the process much cleaner and easier to run a bead.
