Abstract

Spot welding is needed for domestic industry, but the price of the expensive welding and welding power big points lead to less efficient welding for small industries. In this case the spot welding with the low prices and little power is needed. The research method adopted is a literature study after it conducted a survey instrument and then after receiving the results of the survey instrument design is performed followed by a process of making tools. After the tool is finished running the revised drawings done after it conducted the test tools to determine the performance of welding machines. The purpose of this study is that we can know whether home-based resources can be used to weld and then we can determine the performance transformer used for welding machines and welding machines could create a spot for an efficient small industrial purposes and can know the results of the physical welding of the welding machine . To determine the performance of welding transformer and then made three winding transformer with different variations of 365, 635 and 1000 pda primary windings and three windings on all transformers in the secondary chart. Tests carried out on three plates with a thickness. of the test result berfariasi weld. From the third transformer 365 transformer that can only be used to weld on the plate 0.1 and 0.3 whereas in 0.5 plate a long time .. Another transformer is only capable of melting the surface of the plate. From these tests it is concluded that home-based electric power can be used to weld. 365 transformer windings can be used to weld with an output of V = 1.8 and I = 475. with the 365th transformer windings can be made a spot welding machine scale cottage industries. With 365 transformer windings capable of connecting plate well and no damage on the surface of the plate .
