Do a container test to measure coolant flow
The container test helps to find problems with slow coolant flow.
1. Get an empty container that has a minimum capacity of 3.79 liters (1 U.S. gallon) and volume
measurements, if possible.
2. Remove the power from the cutting system.
3. At the rear of the cooler, disconnect the red coolant return hose that goes to the plasma power supply
from the red coolant return fitting that is on the coolant hose manifold.
Use the container to collect coolant leaks if necessary. Remove the coolant from the container before
you start the test.
