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. Us-
ing 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 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 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.
Cooling System Requirements
Coolant must be added to the system on installation. The amount required varies with torch leads length.
Victor Thermal Dynamics recommends the use of its coolants 7-3580 and 7-3581 (for low temperatures).
