Flow requirements for coolant

The correct coolant flow rate is necessary for cutting system operation. If the flow rate is too low or too high, the system will stop automatically to prevent damage.

• The maximum coolant flow rate is 11.36 liters per minute (3.0 US gallons per minute).
• The minimum coolant flow rate is 3.79 liters per minute (1 US gallon per minute).

The cutting system stops automatically if the flow rate reaches the maximum or minimum flow rate. Automatic, low-flow shut-off protects the coolant pump from damage from low-flow or no-flow conditions. Automatic, high-flow shut-off protects the torch and leads from damage from a blow-out event.
