Torch coolant requirements
The system is shipped without any coolant in the tank. Before filling the coolant system, determine what coolant mix is
correct for your operating conditions.
Observe the warning and cautions below. Refer to the Material Safety Data Sheets appendix for data on safety,
handlingand storage of propylene glycol and benzotriazole.
Premixed coolant for standard operating temperatures
Use Hypertherm premixed coolant (028872) when operating in a temperature range of -12°C to 40°C (10°Fto104°F).
Refer to the custom coolant mix recommendations, if temperatures during operation are ever outside of this range.
Hypertherm premixed coolant consists of 69.8% water, 30% propylene glycol, and 0.2% benzotriazole.
WARNING!
COOLANT CAN BE IRRITATING TO SKIN AND EYES AND HARMFUL OR FATAL IF
SWALLOWED.
Propylene glycol and benzotriazole are irritating to skin and eyes, and harmful or fatal if swallowed.
Upon contact, flush skin or eyes with water. If swallowed, seek immediate medical attention.
CAUTION!
Never use automotive antifreeze in place of propylene glycol. Antifreeze contains corrosion inhibitors
that will damage the torch coolant system.
Always use purified water in the coolant mixture to prevent damage to the pump and corrosion in the
torch coolant system.
