摘要

A control circuit for arc welding components to a workpiece, a sequencing control determines the timing of the return and forward placement strokes of the welding gun together with the welding arc. A monitoring voltage from the precurrent arc, determined by the weld surface condition, is converted to a correction voltage, through a set point comparator, and superimposed on a control voltage, which adjusts the output current of the welding operation to the resistance valve of the pre-current arc.
