K1668-1 - Lincoln Electric 16ft Flexible Fume Extraction Hose with Magnetic Hood

High-Performance Fume Extraction for Complex Geometries

The Lincoln Electric K1668-1 Hose and Hood Set is a specialized accessory engineered to expand the operational capabilities of industrial fume extraction systems. Designed to address the challenges of Local Exhaust Ventilation (LEV) in non-standard welding environments, this set provides a robust solution for capturing particulates at the source, even in areas where rigid extraction arms cannot reach. The assembly features a 16-foot (approximately 4.8 meters) flexible hose, offering significant reach for maintenance, repair, and fabrication tasks performed on large or complex workpieces.

Technical construction of the hose prioritizes both airflow efficiency and mechanical durability. With a diameter of 146 mm (5.75 inches), the hose is sized to maintain optimal air velocity, ensuring that fume capture velocities meet industrial hygiene standards without placing excessive static pressure on the extraction unit's fan. To withstand the harsh conditions typical of heavy fabrication environments, the hose is reinforced with external steel rings. These rings provide critical structural integrity, preventing the hose from collapsing under negative pressure and offering crush resistance against foot traffic or heavy equipment. They also serve as abrasion guards when the hose is maneuvered across concrete floors or rough metal surfaces.

A defining feature of the K1668-1 is its integrated magnetic hood. This component significantly enhances process efficiency by allowing the operator to secure the extraction point directly to ferrous base materials. Unlike friction-based positioning systems that may drift or require frequent adjustment, the magnetic hood ensures a stable and precise intake position relative to the weld pool. This is particularly critical in "hard-to-access" applications, such as internal vessel welding, chassis fabrication, or structural steel erection, where maintaining the capture zone is essential for welder safety and regulatory compliance.

This accessory is compatible with a range of Lincoln Electric fume extraction units and is an essential tool for facilities aiming to reduce worker exposure to hazardous welding fumes, including hexavalent chromium and manganese. By facilitating effective source capture in difficult locations, the K1668-1 supports a comprehensive approach to air quality management in the industrial sector.
