K1655-8 - Lincoln Electric LFA 3.1 Prism Wall-Mount Extraction Arm, 10 ft

Industrial-Grade Fume Capture Technology

The Lincoln Electric K1655-8 LFA 3.1 Wall-Mount Fume Extraction Arm is a critical component for industrial welding environments requiring efficient local exhaust ventilation. Engineered as part of the Prism fume extraction series, this 10-foot flexible arm is designed to capture welding fumes at the source, preventing them from entering the welder's breathing zone or dispersing into the facility. The unit features a robust wall-mounting mechanism that conserves valuable floor space while providing a substantial reach of 10 feet, making it suitable for medium to large welding bays where maneuverability is essential.

Technically, the LFA 3.1 is distinguished by its internal balance system. Unlike inferior arms that may drift or sag over time, this system ensures that the arm maintains its fixed position once set, providing reliable stability during long welding operations. The construction utilizes high-quality materials that are specifically treated to be dent and scratch-resistant, reducing the need for cosmetic maintenance and ensuring longevity even in harsh heavy fabrication environments. The arm's tubing is designed to optimize airflow efficiency, minimizing pressure drop across the system when connected to a compatible extraction fan or central filtration unit.

Operational control is enhanced through the inclusion of a 360-degree rotatable hood. This feature allows the operator to orient the capture zone precisely relative to the weldment, accommodating various welding positions including flat, horizontal, vertical, and overhead. Furthermore, an integrated baffle within the hood assembly permits the manual regulation of airflow. This allows operators to adjust the suction velocity as needed, balancing effective fume capture with the need to maintain shielding gas coverage. The K1655-8 represents a synthesis of durability, ergonomic design, and aerodynamic efficiency, making it a preferred choice for safety-conscious industrial facilities.
