Abstract:

A method for dressing a pair of weld gun tips on a weld gun controlled by a robot is disclosed. The method comprises the steps of: placing an alignment tool in a mounting head of a tip dresser tool, with the alignment tool including a central alignment bore having a diameter corresponding in size to a diameter of the pair of weld gun tips; teaching a robot path to cause the pair of weld gun tips to slide into the central alignment bore while the alignment tool is mounted in the mounting head; removing the alignment tool from the mounting head; inserting a cutter head into the mounting head; using the taught robot path to bring the pair of weld gun tips into contact with the cutter head; and dressing the weld gun tips with the cutter head.
