In addition, there is a pressure switch on the delivery circuit
to safeguard the welding torch by monitoring the pressure of the coolant.
When a pressure drop occurs due to a lack of fluid or a blocked pump, the pressure switch reports the anomaly to the
power source and the power source automatically stops.
This anomaly is indicated on the power source display.
