This publication presents the basic concepts of the air carbon arc cutting (CAC-A)1 process to provide a fundamental understanding of the process and its variables. In addition, specific technical data are presented as a guide in establishing optimum operation of this process. This standard makes use of the U.S. Customary Units. Approximate mathematical equivalents in the International System of Units (SI) are provided for comparison in parentheses ( ) or in appropriate columns in tables and figures. Annex A is included to identify metric equivalents if the reader requires precise conversion information.
Safety and health issues and concerns are beyond the scope of this standard and, therefore, are not fully addressed herein. Some safety and health information can be found in Section 9. Safety and health information is available from other sources, including, but not limited to, ANSI Z49.1, Safety in Welding, Cutting, and Allied Processes, and applicable federal and state regulations.
