0467801001 - ESAB Cooling Fan for LHN/LTN Welders

Restore Your Welder's Performance with the ESAB 0467801001 Fan

Is your ESAB LHN or LTN welder tripping the thermal overload light more often than usual? Or perhaps you've noticed the machine is unusually silent when turned on? A failed cooling fan is a common issue that can bring your welding projects to a grinding halt. The ESAB 0467801001 is the direct replacement fan assembly you need to get your machine running cool and reliable again.

Welding machines, especially compact inverters like the LHN series, rely heavily on forced air cooling to maintain their duty cycle. The duty cycle is the percentage of time in a 10-minute period you can weld at a specific amperage before the machine needs to cool down. If your fan is spinning slowly, making grinding noises, or has stopped completely, your duty cycle effectively drops to zero. Continuing to weld with a compromised cooling system puts your main power board at risk of burning out—a repair that is significantly more expensive than replacing a fan.

This OEM fan is designed to plug directly into the existing harness of your LHN or LTN unit. There is no need to cut wires or crimp new connectors. The mounting holes align perfectly with the chassis mounts, making the swap a straightforward job that can typically be done with standard hand tools in under 30 minutes. The fan blades are balanced to reduce vibration, and the motor is sealed to resist the ingress of conductive grinding dust and metal shavings, which are the enemies of all electronics.

Installation Tips:

Before installing the new fan, it is highly recommended to blow out the inside of the machine with compressed air. Dust buildup on the heat sinks acts as an insulator, trapping heat even if the new fan is working perfectly. By cleaning the internals and installing this fresh 0467801001 fan, you are essentially restoring the machine's cooling efficiency to factory levels. Don't let a small part stop your big jobs. Keep your arc stable and your machine cool with this genuine ESAB replacement.

Why Choose OEM?

• Correct Airflow: Generic fans might fit physically but often lack the static pressure to push air through dense heat sink fins.
• Electrical Safety: Designed for the specific voltage and current draw of the LHN/LTN control board.
• Longevity: High-quality bearings ensure the fan lasts for years, not just weeks.
