Welding paws are the best solution for manual welding, where the operator moves around the workpiece during the welding process. They are installed directly on the workstation and remove fumes and gases directly at source before they are released into the working environment. Gram Clean Air paws are used in both small and large companies where it is important to ensure the health of workers and meet environmental and safety requirements.
The optimum distance is 15-30 cm close to the welding point. The closer the pawl, the more effective the pick-up. A pawl that is too far away will not be able to trap harmful gases sufficiently.
Yes, Gram Clean Air paws are suitable for welding stainless steel. Welding stainless steel produces harmful chromium compounds, which is why a W3 system with high filtration efficiency is particularly important.
The pawls can be connected either to an individual filter unit (e.g. Gram Clean Air GCA series) or to a central dust collection system. The connection is made via a flexible duct that can be adapted to the appropriate length and direction.
Filters should be checked regularly and replaced according to the intensity of use. Gram Clean Air units are equipped with a filter fullness indicator to warn when the filter needs to be changed. Typically, the filter is changed every 2000-4000 operating hours.
