摘要：
A device to control operation of a power source for an electric arc welder comprising an oscillator for inducing a high frequency voltage into a series circuit including the welding gap, a detector tuned to the high frequency for sensing the level of current in the series circuit at the high frequency and an output circuit to create a start signal when the received signal level exceeds a given value representing a resistance in said gap below a given amount.
