Spot Welding Wiring Diagram. D do not use damaged welding cables. The shorter mot is a very good idea.
Schematic diagram of resistance spot welding. It should be obvious even to the causal observer that if you put 2550 degree liquid steel over a galvanized coating that boils at 1350 degrees f. Brass is not suitable below.
Copper is used for the electrodes as it has a high thermal conductivity and low electrical resistance compared to most other metals ensuring that the heat is generated preferentially in the work pieces rather.
The term resistance welding comes from the fact that it is the electrical property of resistance of the metal being welded. The molten metal from the two pieces flows together. Once i needed to have extra long arms 50 cm on a spot welder to reach the middle of a sheet and the only thing l had at hand was copper tubes and steel rod. There are many tutorials on how to prepare the transformer to accept your new windings.
