ABSTRACT:
An improved electrode construction for use in cutting and gouging where air under high pressure is used to blow away molten metal. The improvement in a structure where a carbon is employed with a covering surrounding the carbon with an air passage formed at least in part by the covering. The air passage transmits high pressure air to the area where the cutting and/or gouging takes place.
