ANALISA PENGARUH JUMLAH LILITAN DAN DIAMETER TEMBAGA PADA TRAFO TERHADAP DAYA OUTPUT MESIN SPOT WELDER AND SOLDERING IRON SEMI PORTABLE

Abstract

In the welding process, there are still some obstacles, namely the welding equipment used still requires a large amount of electricity. For this reason, a welding tool that has relatively small electrical power is needed, it requires a transformer that is able to cut electrical power. To answer the above problems, the author is interested in developing a MOT (Microwave Oven Transformer) transformer whose secondary winding is modified as an alternative to conventional transformers so that the electric power becomes small. This plan aims to make a transformer with an output power of 450 Watt on a "semi-portable spot welder and soldering iron machine" and capable of operating at home with 450 VA electricity. The process of making a transformer begins with determining the output power generated by a MOT (Microwave Oven Transformer) transformer. The design method determines the number of turns and the diameter of the copper in the transformer by using copper with a diameter of 12 mm and 16 mm, while the work concept determines the basic concept of calculating the output power and efficiency of the MOT (Microwave Oven Transformer) transformer.
