W7003016 - ESAB Thermal Arc W7003016 Replacement Thermistor Sensor

Reliable Thermal Protection for Your Welder

The ESAB W7003016 Thermistor is a critical replacement component designed specifically for select Thermal Arc and ESAB inverter welding machines, including the popular Thermal Arc 95 S and 201 TS models. As a genuine OEM part, it ensures that your equipment continues to operate safely by accurately monitoring internal temperatures.

Inverter welders generate significant heat during operation, particularly in the power transistors and rectifiers. The thermistor acts as the machine's safety watchman, constantly relaying temperature data to the control board. If the machine exceeds its rated duty cycle or if airflow is restricted, this sensor triggers the thermal overload protection, shutting down the output to prevent catastrophic failure of expensive internal components.

When a thermistor fails, your machine may display error codes, refuse to weld, or—worse—fail to shut down during overheating events. Replacing a faulty sensor with this authentic ESAB unit restores the factory-specified protection logic. It comes pre-wired with the correct connector for a hassle-free installation, allowing you to get your welder back in service quickly.
