Arc welding machine parts name.
Welding machine has a step down transformer to reduce the input voltage of 220 440v to 80 100v.
A microprocessor then switches the stored energy into a transformed where it is converted into the desired output current.
The machine stores the high voltage current from the wall outlet in a capacitor.
Motor generator set or diesel petrol engine.
It is a type of welding that uses a welding power supply to create an electric arc between a metal stick electrode and the base material to melt the metals at the point of contact.
The welding machine used can be a c.
The various equipments required for electric arc welding are.
Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal and the melted metals when cool result in a binding of the metals.
