How To Make Welding Transformer At Home. Wind the two copper wires several times at least 12 turns around the ends of the core steel bolt. The inner part should be slightly larger than the core core and the cheeks should freely enter the transformer window.
The type of insulation on it should be fiberglass or cotton. So if we have a 650 watt microwave transformer then at 50 volts we can draw 65050 approx 13 amps for a mains current in of 3 amps. Primary windings secondary windings and a laminated iron core.
Transformers have a constant amperage characteristic that makes them ideal for welding.
To perform on the welding machine the first layer of the insulating winding it is best to use a winding wire made of special-purpose copper and at the same time necessarily heat-resistant. To make a welding machine for each transformer you will need to wind 18 turns 6 rows in height and 3 layers in thickness. Power Voltage X Current. For a 800 watt transformer 50 volts 16 Amps and 1000 watt 50Volts 20 Amps.
