Custom Coolant mix for cold operating temperatures (below-12°C/10°F)
Use the chart below to determine what percentage of propylene glycol to use in the mixture.
Mix 100% propylene glycol (028873) with the premixed Hypertherm coolant (028872) to increase the percentage of
glycol in the premixed Hypertherm coolant. The 100% glycol solution can also be mixed with purified water (see the chart
below for water purity requirements) to achieve the required protection from freezing.
Note: The maximum percentage of propylene glycol should never exceed 50%.

CAUTION!
For operating temperatures colder than the temperature stated above, the percentage of propylene
glycol must be increased. Failure to do so could result in a cracked torch head, hoses or other damage
to the torch coolant system due to freezing.
