NO COOLANT FLOW
During normal operation, the system checks for coolant flow. After the coolant pump has been turned on and the active torch has been selected, this error is activated if the flow sensor does not indicate coolant flow within a 12 second delay.
(1) Check that the torch head is installed. For two torch systems, check that either the inactive torch or a dummy head is installed. (2) Check that the coolant tank has enough coolant. (3) Check that the air has been purged from the coolant lines. See
Cooling System Servicing
in the front of this section. (4) make sure
that the coolant lines are not obstructed or kinked. (5) Make sure that the proper coolant select solenoid is energi
