195746 - Miller Coolant Temp Sender and 130C Thermal Switch

Genuine Miller 195746 Coolant Temperature Sender & 130°C Switch

Maintain the integrity and safety of your high-performance welding equipment with the Miller 195746 Sender, Coolant Temp & 130C Switch. As a professional welder or maintenance technician, you understand that liquid-cooled welding systems rely heavily on precise thermal management to operate at high duty cycles. This component is a critical safeguard within that system, designed to monitor the temperature of the coolant circulating through your power source and torch.

The Miller 195746 is not just a passive sensor; it features a specific switching point at 130°C (266°F). This calibration is essential for triggering safety protocols—such as shutting down the machine or activating warning indicators—before the coolant reaches a temperature that could damage internal components or the welding torch itself. Using genuine Miller parts like this ensures that the resistance values and switching thresholds match the exact specifications of your machine's control board, preventing false alarms or, worse, a failure to detect an overheating event.

At Josef Gas, we prioritize providing authentic OEM replacement parts to ensure your equipment downtime is minimized and your repairs are permanent. This sender is built to the high standards of Miller Electric, offering durability against the vibration, heat, and electrical noise common in industrial environments. Whether you are repairing a TIG runner or a heavy-industrial MIG setup, verifying your machine's serial number and replacing faulty sensors with the correct OEM part is the best way to protect your investment.

Don't compromise on the health of your cooling system. A faulty sender can lead to unmonitored heat buildup, resulting in torch failure or power source damage. Trust the Miller 195746 to provide accurate readings and reliable switching when it matters most.
