OVERVIEW

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.

Product Highlights

  • Genuine OEM Quality: Guaranteed compatibility and performance with specified Thermal Arc models.
  • Safety First: Restores critical thermal overload protection to prevent machine burnout.
  • Easy Replacement: Designed as a direct fit with the necessary cabling and connector included.

Don't risk your equipment with generic sensors. Trust the ESAB W7003016 to keep your 201 TS or 95 S running cool and reliable.

FAQ

It monitors the internal temperature of the welding machine's heat sinks to prevent overheating and manage the thermal overload protection system.

It is primarily designed for the Thermal Arc 201 TS and Thermal Arc 95 S inverter welding machines.

Symptoms often include the thermal overload light staying on even when the machine is cold, or the machine shutting down unexpectedly. A technician can also test it with a multimeter.

Yes, this is the genuine OEM replacement part W7003016 manufactured by ESAB (who owns Thermal Arc).

Yes, the thermistor assembly typically comes pre-wired with the specific connector required for the control board.

It is not recommended. Inverters are calibrated to specific resistance curves; using a generic part can lead to improper temperature readings and potential machine damage.

It is usually mounted directly onto the main aluminum heat sink where the IGBTs or diodes are located.

If the light is on due to a faulty sensor (open or short circuit), replacing it will fix the issue. However, the light could also indicate a real overheating event or a fan failure.
