Title: Connection winding spot welder - has pulsed current operated and penetration controlled main and return electrodes on commutator riser and face respectively
Inventor: OHUCHI YASUSHI
IPC: H01R39/32
Filed: 1977-05-26
Abstract: The welder comprises a main electrode (7) and return current electrode (6) which bear on the commutator riser and face respectively and are applied to each segment in succession. Welding current is provided from a pulsed generator (8, 9, 10). The depth to which the main electrode (7) presses into the top of the riser during a current cycle is detected (13) and used to control the cycle length of the current. The depth signal (13) is compared with a reference (21) in a comparator (20) and used to interrupt the current when parity of signals is reached. The number of such cycles per weld can be preset. Control of electrode penetration removes the risk of damage to or destruction of the riser by maintaining electrode pressure when the metal is plastic or molten.
