Capacitor-Discharge Stud Welding Machine operates on a power supply rate of 220V AC, at a frequency rate of 50 Hz. The Stud Welding Machine ensures leak-proof fastening and is free from deformation, burn-through and marking. The Stud Welding Machine uses a low voltage electrostatic storage system in which the weld energy is stored in a capacitor bank of high capacitance. The Stud Welding Machine is offered in a dimension of 370mm X 300mm X 250mm and approximate weight range of 20kgs. Capacitor-Discharge Stud Welding Machine can be availed in readily portable or bench mounted version.
