Welding Fume is generated in nearly all welding process and employers have a legal obligation to ensure sufficient measures are taken to protect the welder from this hazard. Safe working environments can be created and exposure to welding related fume can be reduced dramatically if the correct fume control solution is applied to the working environment.
There are a wide variety of fixed and mobile solutions for welding fume control and it is always advisable to extract fume as close to the source as possible. The following solutions can be used to minimise the welder’s exposure to welding related fume
On-Torch Fume Extraction: The Weldability FE range of MIG torches allow connection to a suitable fume extraction system, such as the ProtectoVac or ProtectoTwin mobile units and remove fume just above the welding nozzle to minimise fume leaving the immediate welding zone.

Mobile Fume Extraction Systems: For working environments where a welder may be operating in multiple locations during a working week, it may be more viable to consider a unit that can be manoeuvred to different locations. There are range of different models available to suit a wide range of requirements. The ProtectoVac and ProtectoTwin are mobile units which can be easily transported around multiple locations because of their compact, lightweight design. The ProtectoXtract, ProtectoReclenz and ProtectoAutoclenz offer solutions for heavier duty applications and are able to extract stainless fume.
Mobile extraction units
VTA (Vent to Atmosphere): For a fixed welding bay a VTA solution would be more suitable. These feature a wall mounted fan and are available with a variety of flexible extraction arm lengths to suit the specific welding bay in question. The hood is placed close to the welding zone and the fume is then vented out of the building to the atmosphere
Custom Solutions: For facilities with multiple welding bays, a customer solution can be designed with a fan, filtration, ductwork and extraction arm configuration to suit the client’s needs. To ensure custom solutions work effectively it is important to ensure an appropriate extraction unit is used along with correctly configured ductwork and filtration. The system should be installed, commissioned and tested in accordance with Health & Safety Guidance 258 (HSG 258).
