Abstract

An arc welding or cutting torch includes a torch body, a jacket encased within the torch body, an electrode holder encased within the jacket and a heat dissipater interposed between the electrode holder and the jacket. The heat dissipater is made of a material with a greater thermal conductivity than the material forming the electrode holder.
