This paper represents the portability of resistance spot welding machine and study of various factors like the thermo-effect of nugget growing in single-phase AC resistance spot welding and heating of electrodes during spot resistance welding. The designed welding machine is very less in weight with same strength of the regular spot welding machine with more degree of freedom to work with. The first thing is the fabrication of the portable spot welding machine which is divided into two phases, first is the formation of basic circuit of machine which includes small transformer of 1.2KVA with output voltage 0 to 2volt with 2-gauge wire & power switch and second is the formation of body and arm mechanism of the machine. Also the study is on various the factors which come into light when process of spot welding takes place. One such factor is nugget formation. The nugget formed in the work piece plays a crucial role in joining structure. Nugget forming process is not visible and also hard to test.
