WARNING
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, drink water and call a
physician immediately. Do not induce vomiting.
Caution: Always use propylene glycol in the coolant mixture. Do not use anti-freeze in place
of propylene glycol. Anti-freeze contains corrosion inhibitors that will damage the
torch coolant system.
Always use purified water in the coolant mixture in order to prevent corrosion in the
torch coolant system. The hardness of purified water should be between .206 and
8.5 ppm. If using a conductivity meter to measure water purity, the recommended
level is between .5 and 18 µSiemens/cm at 77° F (25° C).
