The circuit provides linearized welding voltage and current to an welder (W) by compensating D/A converter (CV), voltage follower circuit (Q2), differentiate circuit (Q3), zero auto circuit (ZA), and resistor value (Rw). The zero auto circuit (ZA) provides controlled signal voltage to input tap (6',7') of the welder (W), which voltage is an output of software corresponding to the input signal so that the compensated linear wave form is provided.
