ABSTRACT:
An override control apparatus and method for parameter adjustment of digitally based welding process programmers is provided for making modifications to a pre-programmed weld parameter schedule during real time welding. Initial values for welding head current are initially provided to a programmer, and during the real time welding interval, means are provided for overriding and updating the data. The programmer repetitively and frequently makes calculations so that the output value of current supplied to the welding head is provided frequently. In addition to the current output signal, a speed output signal is provided to control the speed of the welding head relative to the workpiece. The current output and speed output signals are generated with the same time base in synchronism.
