DIY Spot Welder

DIY Spot welder


I happen to get this junk microwave oven from one of a friend.

So I decided to make use of its MOT to build a spot welder. Take outmost care when handling the transformer especially when removing the secondary winding.


The necessary materials:



Two windings of #4 AWG wire from a welding cable


 Making a wooden enclosure






Testing  and current draw
