Coolant Control and Leak Detection for Automotive Robotic Welding Systems

Proteus Industries is the world leader in automotive weld coolant monitoring and water saver products. The Proteus WeldSaver™ protects welders from overheating, saving expensive weld components such as transformers, electrodes, caps, and water-cooled motors. For over 20 years, leading automotive OEMs have counted on Proteus WeldSaver technology to monitor critical cooling circuits, detect leaks and cap loss, automate valve shut off, and provide a state-of-the-art web-based monitor compatible with popular robot teach pendants. The WeldSaver integrates to your PLC, robot, and welder using industry-standard, ODVA-compliant data formats for inputs and outputs, making integrations streamlined.

In its most simple form, the WeldSaver protects welders by monitoring the incoming and outgoing water (or other) coolant for the robotic welding system.

 In the event that the flow rate or the temperature exceeds pre-defined limits, the WeldSaver sends a signal to the controlling devices (PLC, weld controller, robot). Signals can be warnings or faults, depending on the set-points values. 

 

Once the welder has turned off, the WeldSaver functions as a water saver to turn off the incoming water using a pneumatic or electric solenoid valve. All operational information is collected by the WeldSaver and displayed on the web interface (or robot pendant) in an intuitive and easy-to-understand format for operators.
