ABSTRACT:
The invention deals with a new miniaturized welding machine, suitable for light soldering jobs.
In general lines, the invention consists of the construction of a machine for electric welding with characteristics of a source of constant current. For this purpose, in the central leg of the core (15), a bundle of steel blades in a shape similar to that of the letter "E" (16) faced by the letter "I" (17), a primary coil (18) and a secondary coil (19), are placed on the opposite ends of the central leg of the core, remaining between them the space occupied by a physical separator (20) of both coils; what happens is that, when to the secondary coil is connected a charge resistance (21), it is produced the characteristics of a constant current source, suitable to determine the fusion of electrodes allowing the performance of the desired welding.
