The cooling of electrodes is very important for the operation. If the electrodes over heat during normal use, the voltage drop will change significantly and make it difficult for resistance feedback to the welding processor to make the proper corrections. The water tubes inside the electrodes must be placed to generate a turbulence of water to wash away heat buildup.

This presentation will show how you can determine if the water cooling is sufficient during the OFFSET RESISTANCE check that will be required during the initial setup.
