The machine is designed to serve with a 250A output. It is divided into two pats: primary and secondary. The primary part, which supplies voltage to the machine, has 180 turns of 2mm2 S.W.G 14 copper coil. The secondary part is made up of 45 turns of 4mm2 S.W.G 8 copper coil.

Both turns are wound on separate laminated core limbs. Induction transfers voltage from primary to secondary turns.

When connected to a power source, the machine has a power switch that allows it to be turned on or off. The indication light simply indicates whether the machine is turned on or off, which is controlled by the power switch.

When connected to the machine, it looks at the temperature of the machine and starts once the machine is turned on.

By varying the spacing between the primary and secondary windings, the welding current can be adjusted. When the crank is turned clockwise, the insulating block between the two windings moves downward, increasing magnetic flux leakage and inductive impedance and thus lowering the welding current in the secondary windings. Additionally, as the insulating block is moved upward, away from the two turns, the magnetic flux leakage and inductive impedance are reduced, causing the welding current to increase.

1.0            INTRODUCTION

The Arc welding machine is the type that uses electric power as an input, which is supplied through the primary winding and then transferred to the secondary winding by induction, which can then be used to perform welding work by connecting the welding cables to the output terminal.

The machine’s output is designed in such a way that it can be varied by turning the crank in either a clockwise or anti-clockwise direction to increase or decrease the output current depending on the size of the material to be used on.
