K1655-13 - Lincoln Electric LFA 4.1-LC 13ft Low Ceiling Fume Extraction Arm

Technical Overview of the Lincoln Electric K1655-13

The Lincoln Electric K1655-13 LFA 4.1-LC is a specialized fume extraction arm designed to address the specific challenges of industrial environments with height restrictions. Unlike standard tubular arms that may require significant overhead clearance for articulation, this low-ceiling model maintains a profile suitable for confined vertical spaces while extending a full 13 feet (approximately 4 meters). The unit is engineered with a robust internal balance system. This mechanism is critical for operational efficiency; it allows the operator to extend, retract, and position the arm with minimal physical effort, ensuring that the hood remains stable at the desired coordinates without "drooping" or drifting during welding operations.

The capture efficiency of the K1655-13 is centered around its 360-degree rotatable hood. Effective source capture requires precise placement relative to the arc. Lincoln Electric specifies a positioning range of 6 to 12 inches (152-304 mm) from the weld source. This proximity creates a capture velocity sufficient to entrain welding fumes, particulate matter, and smoke before they can enter the welder's breathing zone or disperse into the general facility atmosphere. The hood's rotatability ensures that even in complex weldments or awkward positions, the extraction point can be oriented correctly. Furthermore, an integrated baffle within the hood assembly provides operators with manual control over airflow, allowing for adjustments based on the specific welding process and fume generation rate.

Durability is a key factor in MRO environments. The arm is constructed to withstand the rigors of heavy fabrication shops. The exterior is resistant to dents and scratches, reducing the likelihood of structural damage that could compromise airflow or mechanical movement. This resilience translates to lower long-term maintenance costs and extended service life. The wall-mount configuration serves as a permanent station solution, ideal for dedicated welding bays in automotive, shipbuilding, and general fabrication sectors. By integrating the K1655-13 into a central extraction system or a dedicated fan unit, facilities can effectively mitigate occupational health risks associated with welding fumes.
