Aim of the work is to give overview of welding transformers and construct a working welding. For that has been explained the operating principles of the transformer and shown needed calculatsions and comments for constructing. Given work ise useful for a person who is intrested construct a transformer. Transformer winding is becoming a lost art, many people despair about where to find some very specific transformer, and the cost of having one professionally wound to specifications is too expensive. In this work were used a old transformer and rewinded it to suit our purposes for keeping the cost of the transformer as low as possible. The tranfsormer had to be small as possible, but withstand nominal current of 60A. The transformer output nominal voltage approximately 50V for easy ignition of the arc.
