951346 - ESAB 8.75-Inch Replacement Cooling Fan Blade

Technical Overview of the ESAB 951346 Fan Blade

The ESAB 951346 is a specialized replacement fan blade designed specifically for the thermal management systems of ESAB welding power sources. With a precise diameter of 8.75 inches, this component plays a critical role in forced-air cooling, ensuring that internal components such as rectifiers, transformers, and PC boards remain within their operational temperature ranges. In industrial welding environments, the accumulation of particulate matter and continuous operation can lead to the degradation of cooling components. A compromised fan blade—whether cracked, unbalanced, or missing fins—significantly reduces airflow (CFM), leading to premature thermal overload trips and potential catastrophic failure of power electronics.

This OEM part is engineered to match the specific aerodynamic requirements of the original equipment. Unlike generic fan blades which may have incorrect pitch or bore sizing, the 951346 ensures that the static pressure and volume of air moved match the design specifications of the welder's chassis. Proper cooling is directly tied to the duty cycle of the machine; therefore, maintaining the integrity of the cooling system is essential for high-amperage applications where heat dissipation is paramount. The blade is constructed from durable materials capable of withstanding the thermal cycling and vibration inherent in heavy-duty welding operations.

Installation of the 951346 restores the laminar airflow required to eliminate hot spots within the machine cabinet. Technicians repairing ESAB equipment should verify the condition of the fan motor shaft and bearings when replacing the blade to ensure a complete restoration of the cooling subsystem. This part is compatible with select legacy and modern ESAB, L-Tec, and Linde power sources that specify an 8.75-inch axial fan. Utilizing genuine ESAB parts guarantees fitment and performance, minimizing maintenance downtime and ensuring compliance with the manufacturer's thermal ratings.
