Abstract of the Disclosure An apparatus and method for making reliable and repeatable welds between lead battery lugs disposed on either side of a plastic partition. An instrument measures the resistance of the welding jaws, electrode tips and contact of the tips with the battery lugs and sends this information to an interface controller where the amount of current required to generate the heat to make a reliable weld is determined from the resistance measurement. Information is then sent to a transformer controller which energizes a transformer to provide the correct amount of current to the welding jaws. While the welding is in progress, an instrument measures the current flowing through the electrode tips and lugs and this infor- mation is sent to the interface controller for comparison with the determined value. After the weld is complete, the resistance is again measured and, if the weld is found to be inadequate, the battery is marked as a reject and a reject mechanism discards the battery from further process- ing in the assembly line.
