Intelligent Water-Air Control Ensures Stable Operation of Spot Welding Dressing Stations

1. Comprehensive Data Monitoring with Visualized Cooling Status

The Stelon RIP unit is fitted with an industrial-grade display and a built-in dedicated control board preloaded with a complete control program, enabling standalone operation without additional programming. The unit also supports linkage and integration with the customer’s main production line PLC for station-level data interaction and coordinated control. On the water circuit side, it adopts SMC dual flow meters for both inlet and return water to ensure accurate and stable data acquisition. The unit displays core parameters in real time, including inlet flow rate, return flow rate, flow differential and temperature readings. It supports user-defined flow alarm thresholds, triggers instant alarms and logs alarm events under abnormal conditions, enabling full visibility, controllability and traceability of the cooling system throughout operation.

2. Second-Level Leakage Protection with Automatic Water Shutoff

In automatic operation mode, the built-in control board continuously compares the flow differential between inlet and return water. In the event of unexpected electrode cap detachment, loose pipeline connections or other faults that cause water leakage and drive the flow differential beyond the preset threshold, the unit will automatically shut off the water inlet within 1 second to quickly contain cooling water overflow. This prevents station water accumulation, equipment short circuits, water damage to welding guns and other issues, minimizing production downtime and equipment losses caused by failures.

3. Pipeline Purging & Drainage for Drip-Free Cap Change Maintenance

For maintenance scenarios such as electrode cap replacement, the Stelon RIP unit is equipped with a dedicated water extraction cylinder and air supply interface. In manual mode, operators can perform water extraction and air purging on the inlet and return water pipelines to drain residual coolant, ensuring no water spraying or dripping during electrode cap removal and installation. This not only keeps the work station dry and tidy and reduces on-site safety hazards, but also cuts coolant waste and cleaning workload.

Featuring a compact integrated design, the Stelon RIP Water-Air Unit can be directly interfaced with mainstream stationary tip dressers and robot-integrated dressing units, and is widely compatible with automated production scenarios such as automotive body-in-white welding and component spot welding. With its accurate monitoring capability, reliable protection mechanism and user-friendly maintenance design, the unit has become a preferred solution for many welding production lines to improve cooling system stability and reduce operation and maintenance costs.
