Abstract

See full text

A programmable system for controlling maximum machining current. A current limit is entered into the system together with the on time and off time desired. The system operates to use the entered on-time and current values, but the off time will be modified depending on the maximum current limit possible. This will protect the apparatus when an impossible combination has been entered by the operator. The duty cycle is checked against a maximum level such as 87% or a like upper limit.
