ABSTRACT:
An aluminum coated carbon-graphite electrode for use in the air-carbon arc cutting and gouging process. Uniformly coating the electrode with commercially pure aluminum results in a lower operating noise level when the electrode is in use, a cleaner and safer work environment for the user and better performance than conventional electrodes. A further feature of the invention resides in lowering the operating air pressure in the torch when using the new electrodes to further reduce the operating noise level.
