welding current

Okay…this week we will talk about …basic electric for welding. What??????? Why we should know about electrical. We are not electrician or wireman…just to weld the metal. That’s all.
I’m totally agree with you….. but the knowledge of basic electric will help you to improve the skill and how to operate welding machines. Anyway learn about electrical its not too difficult if we really understand how our water pipeline (hydraulic) at home. The principle quite and almost same.

Voltage is like a pressure in pipe
Amperage is flow of water in pipe
Transformer is used to step up or step down the current e.g from 11kv to 230v
Rectifier is used to change Alternate current AC to direct current DC.
Generator is used to produce electrical source for welding machine.
