Although I've never seen these. There is always a built in Thermal, and some sort of fuse. The fuse is probably a Zener diode on the cheaper models. There is probably a relay to control the surge of current when you spot weld, and it probably stuck in an open position. You probably unstuck it disassembling the unit a couple of times. After repeated use it probably will never stick again, at least for the next 10,000 cycles.
