0467118001 - ESAB Replacement Water Flow Sensor Switch

Protect Your Equipment with Genuine ESAB Parts

The ESAB Waterflow Switch (0467118001) is a critical component designed to safeguard your water-cooled welding equipment. In high-amperage TIG and MIG welding applications, efficient cooling is paramount to prevent catastrophic failure of the torch and power cables. This switch acts as the primary safety interlock within your cooling unit, continuously monitoring the circulation of coolant.

When functioning correctly, the switch completes the control circuit only when adequate water flow is detected. If the pump fails, a line becomes blocked, or coolant levels drop critically low, this switch immediately signals the power source to cut the welding arc or inhibit initiation. This instantaneous response prevents the rapid overheating that can melt power cables and destroy expensive torch heads in seconds.

As a genuine ESAB replacement part, this component ensures perfect compatibility with specified ESAB cooling units (check your equipment manual for part number verification). Using OEM parts guarantees that the flow sensitivity and electrical ratings match the original engineering specifications of your machine, maintaining the reliability and safety standards expected from ESAB equipment. Whether you are performing preventative maintenance or repairing a breakdown, this switch is essential for the longevity of your water-cooled welding setup.

Key Technical Benefits:

• Precision Monitoring: Calibrated to detect flow interruptions immediately.
• OEM Reliability: Designed specifically for ESAB cooling system architectures.
• Cost Savings: Prevents expensive torch replacements caused by dry-running.
