Resistance welding electrodes are used by the thousands in the automobile and appliance industry.  Cryogenic processing has been shown to improve the life of these items considerably.  Don't just take our word for it.  Linde Gas Division of Linde AG states this in their paper entitled "Sub-zero Treatment of Steels Technology.  They state that they can make them last longer by a factor of two to nine times.  Linde is a huge supplier of industrial gasses.

That being said, we have another technology that we can add to cryogenics to make them last even longer.  Also, it may be necessary to change some welding parameters in order to take full advantage of the gains offered by processing these parts. 

Besides the electrode tips pictured here, we've also had excellent results with other forms of electrodes such as electrode wheels.
