Homemade 200 Amp Arc Welder using Microwave Transformers

In this video I demonstrate how to make a high current AC stick welding machine using microwave parts, I do this by removing the secondary winding in the microwave oven transformer and rewinding it with fewer turns I already have an arc welder but I wanted to build one which can kick out allot more current for welding thicker steel if you wanted one with less current you could use thinner wire with more turns and using only 2 transformers 00:00 Intro 00:15 Rewinding MOT transformers 02:00 Testing the circuit 03:01 Welding the transformers together 03:34 Making the case 07:05 Painting the case 07:57 Assembling the welder 10:59 Testing the welder The cable crimping tool can be bought here (uk)
