DeltaPoint senses tip loss in resistance welding cells by comparing total inflow and outflow cooling water to the cell. The units can provide tip-loss detection in welding guns, robotic work cells or nonrobotic hard tooling. Up to 13 welding tips can be monitored via one unit. Two flowmeters are used in the monitors to measure water flow in and out and compare flow rate and temperature. If a leak is detected, an alarm stops the robot from welding. DeviceNet interface is a standard feature.
