* Suggested wire size based on United States NFPA 70 National Electrical
Code 2011 edition published by the National Fire Prevention Association. List-
ings 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 tempera-
ture 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 determination of correct wire type and size.
CAUTION
Fuse and wire sizes are for reference only. The installation must conform to national and local codes for the type
and method of wire being used.
Gas Supply
The customer must supply all gas and pressure regulators. Gases must be of high quality. Pressure regula-
tors 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.
