Abstract
A coolant control valve assembly for an automatic welding gun. The assembly includes a manifold having a supply passageway and a return passageway for respectively supplying coolant to and receiving coolant from the welding gun. A controller is used to control the supplying of coolant and is coupled to a sensor which detects a reduction in coolant flow through the manifold relative to predetermined flow rate. A check valve is located in the return passageway of the manifold and closes in response to reduced flow.
