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