Proven expertise since 1993

ENGMAR is specialized in extraction systems for welding and cutting fumes since 1993. Whatever welding processes are used and whatever the industrial constraints, we provide customer specific solutions, enabling both production performance and worker’s protection. A complete range of air- and water-cooled extraction torches for MIG/MAG welding remove welding fumes and gases from the welder’s breathing zone and prevent the fumes from entering the general workshop atmosphere. The extraction torches feature a large range of torch necks and captors as well as an extremely flexible torch...

Our engineering office ENGMAR engineering office designs extraction systems by considering the position and the flow of extraction and fresh air supply devices. In all projects, our engineering office carries out all calculations, diagrams, technical and assembly files, from the design phase to the delivery on site. This includes among others: • Technical study of the project integrating localized, general ventilation, compensation of the extracted air (preheated if necessary), transportation of polluted air and the treatment of polluted air, • Design of the site’s workshop plan, •...

With its integrated engineering office and production plant, ENGMAR guarantees perfectly adapted French made solutions. Maintenance of our installations ENGMAR has a dedicated maintenance service to provide daily support to customers. MAINTENANCE OF OUR EXTRACTION TORCHES A regular maintenance of our welding torches ensures quality weld seams and increases the product lifetime. Maintenance packages include the checking and fixing of the torches. If maintenance offers are not accepted within 2 months, the checking and return of the torche shall be invoiced. MAINTENANCE OF EXTRACTION UNITS:...

Our services and supplies OUR SERVICES: Articles R.4222-20 and R.4222-21 of the Labor Code require the employer to carry out periodical checks of its extraction system to ensure its maintenance and efficiency. We offer on-site periodic inspections by a qualified ENGMAR technician. After the visit, a detailed report is drawn up and includes: • The aeraulic measurements, • The detailed expertise of main bodies constituting the installation, • The update of installation folder. This type of service can be proposed on an annual basis in the form of a periodical control contract. This contract...

MAINTENANCE OF HIGH VACUUM INFRASTRUCTURE: Since a law from October 8th 1987 concerning regular controls on work place ventilation, yearly flow measures have become compulsory. The purpose of these measures is to compare the present values with the first values after installation. Two maintenance contracts include the regular check of the compulsary ventilation systems. Maintenance contrat Level 1: Maintenance contrat Level 1 includes a yearly control of your system, as well as the update of your installation data file including the new measures. Maintenance contrat Level 2: Maintenance...

Welding health hazards Welding fumes are a complex mixture of metals that vary in composition based on the components of the base metal, coatings and/or filler materials and the temperatures used in the welding process. Adverse health effects associated with welding fumes include shortterm illnesses and illnesses resulting from long-term exposure. In case of prolonged exposure, fumes and gases are responsible for the increase in respiratory, cardiovascular and carcinogenic diseases. For those reasons, welding fumes require extraction. The individual particles released during welding are...

Fume extraction efficiency according to extraction means: Distance from welding point The more the extraction zone is remote from the welding point, the more toxic particles get diluted into the working area, which requires a higher extraction flow. 5 - 8x workshop volume per hour Flow rate m3/h General ventilation Extraction hood Extraction table Slit nozzle Low Vacuum Slit nozzle High Vacuum Welding torch Current legislation Although general ventilation can help to control exposure by reducing background levels of fume, it is ineffective for the control of welder exposure. Consequently,...

Guiding principles of welding fume extraction The installation of a welding fume extraction system should consider: 1 Analysis of the workplace and evaluation of the industrial as well as the ergonomic constraints of the welder. Risk assessment of all sources of pollution. Choice and testing of extraction solutions. HIGH VACUUM Central extraction units: page 64 Exhausts and stacks: page 63 Extraction slit nozzles: page 50 Swing arms: page 48 Extraction welding torches: page 14 Workstation cleaning: page 51 Extraction units: page 54

Validation of the technical solution that extracts welding fumes as close as possible to their source in order to reduce operators’ exposure. Dimensioning of the extraction system. Evaluation of the required level of air treatment and choice of exhaust solution.
