On-torch capture
August 1st 2008 Welding fumes can damage the nervous system and respiratory tract and have other adverse effects.
Traditional capture hoods and nozzles work well, but require an element of operator involvement to ensure correct positioning.
For MIG welding it has been possible to integrate the capture nozzle into the welding torch itself and advances have been made to improve weight, efficiency and manoeuvrability.
Nederman, with partner Abicor Binzel commissioned tests at the Health & Safety Laboratory to check the effectiveness of on-torch systems. The report concluded that extraction of welding fumes via the torch can offer very high capture efficiencies and, with the correct welding parameters in place, there was no disturbance of shielding gas and so no detriment to the integrity of the weld.
