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.  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 OEM’s 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.  WeldSaver™ integrates to your PLC, robot and welder using industry standard industry ODVA compliant data formats for inputs and outputs, making integrations streamlined.

In its most simple form, WeldSaver™ protects welders by monitoring the incoming and outgoing water (or other) coolant coming for the robotic welding system.  In the event the flow or the temperature exceeds pre-defined limits, WeldSaver™ sends a signal to the controlling devices (PLC, Weld Controller, Robot).  Signals can be warnings or alarms depending on setpoints. Once the welder is turned off, the WeldSaver then functions as a water saver to turn off the incoming water at the pneumatic or solenoid valve.  All operational information is collected by the WeldSaver, and displayed on the web interface (or robot controller) in an intuitive and easy to understand format for operators.
