K1655-12 - LFA 2.0 Flexible Welding Fume Arm 2m

Lincoln Electric LFA 2.0 Fume Extraction Arm (K1655-12)

The Lincoln Electric LFA 2.0 Fume Extraction Arm (SKU: K1655-12) represents a high-efficiency solution for source capture of welding fumes and particulate matter in industrial environments. Designed with a reach of 6.5 feet (2 meters), this wall-mounted arm is engineered to provide maximum flexibility and durability in demanding fabrication shops. The LFA 2.0 series is distinguished by its hollow tube design, which significantly minimizes internal static pressure drop compared to hose-based arms, thereby enhancing the overall efficiency of the filtration system and reducing energy consumption.

Mechanically, the K1655-12 utilizes a sophisticated external balance system. This spring-assisted mechanism ensures that the arm maintains its position once set, eliminating the common issue of "drift" found in inferior extraction arms. The external placement of the friction joints and springs also keeps these components out of the airstream, reducing turbulence and preventing the accumulation of particulate matter on the moving parts, which extends the service life of the unit and reduces maintenance requirements.

The extraction hood is a critical component of the LFA 2.0, featuring a 360-degree rotatable design that allows for precise orientation relative to the weld pool. The hood is constructed from impact-resistant materials and includes an integrated throttle valve, allowing operators to adjust airflow volume directly at the source. This is particularly useful in multi-arm systems where airflow balancing is required. The 8-inch (203 mm) diameter tube ensures high-volume capture capacity, making it suitable for heavy-duty welding processes including MIG, TIG, and Stick welding, as well as grinding applications when positioned correctly.

Installation of the K1655-12 is streamlined via the included wall mounting bracket, which can be affixed to structural columns or walls. The unit is compatible with a wide range of Lincoln Electric filtration systems, including the Statiflex and Mobiflex series, or can be ducted into a central exhaust system. By capturing fumes at the source, the LFA 2.0 aids facilities in complying with OSHA and local air quality regulations regarding hexavalent chromium and manganese exposure.
