ABSTRACT:
A portable meter for measuring the impedance of a resistance welding circuit between first and second points on the apparatus. The meter is powered by conventional alternating current and conducts a test alternating current through the welding apparatus at such an amperage so that the voltage measured between the first and second points is equal to the impedance therebetween.
