300955 - Miller SA-612-WM Standard Fume Extraction Arm, 12ft x 6in

Optimized Airflow with Miller Standard Extraction Arms

The Miller 300955 (SA-612-WM) is a high-performance Standard Extraction Arm designed to provide superior weld fume capture in industrial environments. Engineered with a focus on airflow efficiency and ease of use, this 12-foot arm features a 6-inch diameter tube that integrates seamlessly with Miller FILTAIR fume extraction systems. Unlike traditional extraction arms that utilize internal support mechanisms, the Miller Standard Arm employs external adjustments. This critical design choice eliminates internal obstructions, allowing air to pass through the arm with significantly less resistance. The result is stronger CFM (airflow) at the hood, ensuring more effective removal of hazardous particulates from the welder's breathing zone.

Precision Positioning and Reach

Covering a wide operational area, the 12-foot length of the SA-612-WM allows welders to access large workpieces without constantly repositioning the base unit. The arm is preassembled and designed for immediate deployment, featuring reliable and accurate positioning across its full range of motion. The external balance system ensures that once the arm is positioned, it stays in place, reducing operator fatigue and frustration. Maintenance is straightforward, with easily accessible adjustment points that ensure the arm maintains its tension and flexibility over years of heavy service.

Advanced Hood Design

At the capture point, the arm is equipped with a durable bellmouth-shaped hood. This aerodynamic design is optimized to funnel smoke and fumes efficiently into the extraction system. The hood features a convenient 360-degree rotation mechanism, allowing for unlimited positioning options to suit complex weldment geometries. Miller's engineering allows this hood to capture weld fumes at a greater distance from the source compared to other hood designs, which means fewer adjustments are required during longer welds. This combination of extended reach, high airflow, and intelligent hood design makes the Miller 300955 an essential component for maintaining air quality and compliance in professional welding shops.
