Welding transformer

The resistance welding transformers step down the line tune of 2 to 20 V. The primary is connected to the line supply and is made from edge bent copper strip insulated between turns with the entire coil also thoroughly insulated. In a typical resistance welding transformer, there are 2 coils of each 8 steps in the primary winding. The two coils can be connected either in series or parallel thus giving rise to 16 different secondary voltages. The secondary winding will have provision for water cooling.
