The Multiquip 7961844603 Fin is a genuine OEM component designed for the BLW-400SSW welder. Sourced directly from Multiquip, this fin delivers the exact fit and material spec the machine was built around, ensuring consistent thermal performance in demanding jobsite conditions. Confirm your model code against BLW-400SSW before ordering to ensure a direct match.
Key Features
- OEM Material Integrity — Manufactured to the same material and dimensional spec as the original, ensuring correct heat-dissipation surface area for the BLW-400SSW cooling system.
- Direct Drop-In Replacement — Engineered to align with the existing mounting points and cooling stack on the BLW-400SSW, requiring no rework or adaptation.
- Confirmed BLW-400SSW Fitment — Correct application for the Multiquip BLW-400SSW welder; always cross-reference part number 7961844603 with your machine's parts diagram before installation.
- Sustained Cooling Efficiency — A damaged or deformed fin reduces airflow through the cooling assembly, leading to overheating and potential engine or alternator damage; replacing with the correct OEM fin restores proper thermal management.
- Genuine OEM Confidence — Supplied as an authentic Multiquip part, meaning the geometry, alloy, and finish match what the machine shipped with from the factory.
A fin is a thin, extended surface within the engine or alternator cooling system that increases the total surface area exposed to airflow, allowing heat generated during operation to dissipate efficiently into the surrounding air. On a welder like the BLW-400SSW, maintaining proper thermal control is critical — excessive heat buildup can degrade weld output quality, shorten component service life, and trigger thermal shutdowns. When a fin is bent, corroded, or broken, airflow through the cooling stack is disrupted, and the machine runs hotter than designed; replacing the fin promptly restores the cooling system to its intended operating capacity.
