274373 - Miller 274373 Coolant Flow Sensor Switch

Protect Your Equipment with the Miller 274373 Flow Switch

The Miller 274373 Flow Switch is a critical component designed to safeguard your water-cooled welding equipment. In high-amperage TIG and MIG welding applications, maintaining consistent coolant flow is essential to prevent catastrophic failure of the torch or gun. This genuine Miller replacement part acts as a sentinel, constantly monitoring the movement of coolant through your system.

When a cooling system fails or a line becomes blocked, the temperature within a welding torch can rise instantly, leading to melted power cables, destroyed consumables, and potential downtime. The 274373 Flow Switch detects these interruptions immediately. By integrating with your welding machine's control circuitry, it serves as a safety interlock, cutting off the welding arc if the flow rate drops below safe levels. This proactive protection saves you money on replacement torches and ensures your production schedule remains uninterrupted.

OEM Quality and Reliability

As an original equipment manufacturer (OEM) part, this switch is engineered to the exact specifications of your Miller cooling system. Unlike generic alternatives that may have incorrect pressure ratings or electrical connectors, the Miller 274373 guarantees a perfect fit and reliable operation. It is compatible with various Miller Coolmate units and integrated cooling systems found in industrial power sources.

Installation and Maintenance

Replacing a faulty flow switch is a straightforward maintenance task that restores the integrity of your welding setup. If your machine is displaying flow error codes or refusing to arc despite the cooler running, a faulty switch is a common culprit. Installing this genuine Miller part ensures that your diagnostics are accurate and your safety systems are fully functional. Trust in Miller's engineering to keep your heavy-duty welding operations running cool and efficient.
