New Welding Thread ?'s for beginners...MIG

[parsonsj]

On my body work welds I do the tack weld thing until the tacks are 3/4" to 1" apart. Then I run a set of stitch welds from one tack to the next. Pull trigger, release, move, pull trigger ... in about 1-2 second periods. You'll get a rhythm that lets the new spot melt into the old one with an over-penetrated weld which is perfect for grinding smooth for bodywork. Be sure and move around to reduce the warping.



Also, watch it when grinding the weld ... that heat can also warp panels.
