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).
