14-11-2004 - Close-up of the spot welding. This is a fantastic (and for me pretty new) way of welding sheet metal. The way to do it is use a medium high setting on the welder, weld a spot (a bit over 1 second), wait a second and weld the next spot with 1/3 overlap. Using short bursts takes away the risk of burning holes in the relatively thin sheet metal and while waiting a second for the next weld, the metal has time to heat up (from the previous weld). This heating up makes sure that the next weld will be strong all through the sheet and that you get very flat welds. /me likes
