NOTE
* Suggested wire size based on United States NFPA 70 National Electrical Code 2011 edition published by the
National Fire Prevention Association. Listings are from table 400.5(A)(2) for flexible cord of certain types rated for
75 deg C in ambient temperatures up to 30 deg C. Using wires of lower temperature rating or different insulation
type may require larger wire size. Derate for higher ambient.
These are suggestions only. Always refer to your local and national codes that apply to your region for final deter-
mination of correct wire type and size.
Gas Supply
The customer must supply all gases and pressure regulators. Gases must be of high quality. Pressure regulators must be double-
stage and installed as close as possible to the gas console. Contaminated gas can cause one or more of the following problems:
• Reduced cutting speed
• Poor cut quality
• Poor cutting precision
• Reduced consumables life.
• Oil or grease contamination from compressed or bottled air can cause fires in conjunction with oxygen.
