Keep your tip clean........ frequent light filing...... clean the steel with acetone.... I use a flat tip on the bottom side and a pointed tip on top...... make sure they sit absolutely flat. ....to keep the long reach of the rods from touching wrap them up with fiberglass tape intended for exhaust pipe manifold from Summit....... use locking pliers on each side of the spot weld when possible........ I often have a third hand helping me (Grant) we hold the spot welder steady on the work bench..... I carry the work to the welder and he fires while I hold it in place.....

Above all...... take the time to test out on scrap pieces...... each time you set up...... so you can adjust the timing.......if it blows or throws sparks something is wrong....too hot too long or not flat......

3 layers is possible but very tricky....... such as door skins!!!! Using the flat head leaves hardly any mark on the finished side.

.....but they do work nice!!!!!!!
