After reading this article you will learn about 1. 2348036826053 abstract a two pole type of an a c variable current welding machine was designed and constructed.

In this way the primary of the transformer is supplied with the same voltage as the power motor circuit of the starter. Simplified diagram of a welding transformer 4 figure 5. Three states of matter. So the usage of welding transformer has significant role in welding compared to a motor generator set.

The welding circuits are properly earthed to protect the welder in the event of a breakdown in the transformer and causing main supply voltage to come into contact with welding side circuit of the transformer. Figure 4 control power transformer wiring diagram. Principle requirement and types article shared by. A welding transformer is a step down transformer that has thin primary winding with a large number of turns and its secondary has more area of cross section and less number of turns ensuring less voltage and very high current in the secondary.
