| abstract | An electrical circuit for a resistance welding machine includes a rectifier connected to an alternating current source, generally at 60 Hz. If the source is three-phase, the voltage of this source should be applied to a full-wave bridge rectifier , to produce an output voltage having a DC component and an AC component. This output voltage is applied to a regulated thyristor inverter which transforms it into a substantially rectangular wave. An electronic circuit controls the thyristor inverter to determine the length of time it operates, the relative pulse width of the rectangular wave, and other desired characteristics of the reverse voltage. The output signal from the inverter is applied to a step-down transformer with a secondary with center tap. The secondary is connected via a full wave rectifier to welding contacts which provide the welding current and the force necessary for a workpiece to perform resistance welding. |
