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