A CLEANING SYSTEM FOR WELDING TORCHES WHICH EFFECTS CLEANING BY MEANS OF COLD TEMPERATURE

摘要

A cleaning system process and apparatus for welding torches performs thecleaning by subjecting the welding torch, including the weld tip, nozzle andgas diffusers,to cooling. The cooling provides a temperature shock sufficient to loosen theweld spatterfrom the torch. In one embodiment the loosened spatter may then be carriedaway from thetorch by either or both of positive or negative fluid pressure, for example anair blast or avacuum line, respectively. The cooling maybe done by subjecting the torch to apressurizedflow of coolant medium such as dry ice pellets or the like. The system mayfurther cleansethe torch with an anti-spatter compound which can be applied by mixture withthe coolantmedium if desired. The cleaning system process is thorough, quick, subjectsthe torch tolittle stress, and improves performance of the nozzle including operation timebetweencleanings.
