![]() The arms, sometimes called snorkels, vary in diameter and length, can be positioned from 6 – 15 inches from the welding fume generator and typically have an extraction volume of 500 – 1,000 CFM. ![]() ![]() The most effective solution for removing and mitigating welding fume is close or at-source extraction. Arms can be fitted to both stationary and mobile vacuum and filter units. Nederman has a wide range of extraction arms in different designs. Welding smoke and fume extraction at-source with arms The necessary components to achieve proper source capture of welding fumes are an easily positioned fume extractor with a well-designed hood, proper airflow through the fume extractor and a conscientious welder who will position the hood in a manner that will draw hazardous fumes away from his or her breathing zone and avoid to spread the smoke in the premises. With over 60 years of industry experience, we can provide application review, solution recommendation and implementation, system design, engineering and installation, product and system support, commissioning, diagnostic and service maintenance programs, assistance with meeting clean air regulations and standards and energy efficient solutions. Nederman offers a full portfolio of portable, stationary, central and custom engineered solutions to control and mitigate welding fume and cutting smoke within the production environment from common welding processes, including MIG, TIG, GMAW, FCAW or SMAW. Using this method, the risk of the welder or operator being subject to hazardous fumes is minimised. Wherever it is a viable solution, it has been proven that extraction at source is the most effective and efficient method of capturing and removing welding and similar fumes. Extraction at source is the most efficient capturing solution for welding and cutting fumes The customer will be educated on the solution's approach, the extraction equipment operation and integration into the process and system maintenance. Education and training is an essential part of any successful solution. After a thorough analysis and interview, we recommend a solution that will best protect the worker while maintaining efficiency, productivity, quality and work zone cleanliness. Our solution starts at the process so we understand the job and worker procedure. It builds up on work stations and can infiltrate machinery and electronics causing damage and creating the need for additional housekeeping, which can add another layer of maintenance and overhead cost.Īt Nederman, worker health and safety are primary concerns, as they affect process efficiency, productivity, quality, costs and successful job completion. ![]() When the fume plume cools, the particulate settles to the work space. Because welding fume is a thermal process, the particulate is suspended in the ambient air space. Ventilation is a primary solution step to mitigate employee welding fume exposure. In many countries, strict personal exposure regulations and standards such as OSHA, PEL or ACGIH TLV are heavily enforced to minimize worker exposure to hazardous metal particulate that can be present in welding fume. International health organizations recognize the importance of preventing health risks associated with fumes and smoke generated during arc welding and thermal cutting. Extraction at source is the most efficient solution for welding fume extraction ![]()
