![]() ![]() Because very fine and precise weld seams are often produced by this process, the TIG torch must be extremely handy as well as lightweight and ensure an ideal view of the process – and so must a TIG fume extraction torch. TIG welding is used in applications where the weld seam should have a particularly good appearance. Since with this concept the TIG wear part clamping sleeve is no longer required, this also has a positive effect on stock-keeping and operating costs. This contains clamping sleeve and clamping sleeve housing combined in one part, offers a large surface for current transmission and heat dissipation and ensures perfect positioning of the tungsten electrode. In addition to the newly developed, patented, combined protection and extraction nozzle, the xFUME ® TIG fume extraction torches use ABICOR BINZEL's 1000-times proven high-performance wear part concept with electrode holder. Suitable fume extraction units from ABICOR BINZEL for xFUME ® TIG: ![]() The cleaned air is then released back into the environment. The fumes are discharged into the mobile extraction unit, where they are collected in the W3 filter and the harmful particles are filtered out. The welding fumes released during the welding process are extracted with the help of a special TIG extraction nozzle at the front end of the TIG extraction torch and thus directly at the point of origin. A low volume flow at high negative pressure flows at a high flow rate of the fumes extracted. The FES-200 W3 and FEC W3 welding fume extraction units are such extraction units and, together with an xFUME ® TIG, form perfectly coordinated welding fume extraction system solutions.Įxtraction at the source in combination with a fume extraction unit is carried out with high vacuum systems. ![]() Extraction units with filter class W3 are allowed to release the filtered air directly back into the environment. The two xFUME ® TIG extraction torches from ABICOR BINZEL are lightweight, handy fume extraction torches that use a mobile fume extraction device to collect and filter out the harmful particles at their point of origin. TIG welding with fume extraction is no less important than extraction for MIG welding and MAG welding, despite lower fume emission during welding. These gases can or may only be absorbed with a special filter with a W3 separation degree and disposed of in accordance with local environmental regulations. They arise during the welding of stainless steel and are considered as a cause of cancer according to various studies. Nickel oxide and chromium (VI) compounds are extremely harmful gases produced during TIG welding. ![]() The low level of fumes produced during TIG welding also helps to increase the formation of ozone: Less fumes allow the UV rays to spread more easily. This means that ozone formation can occur even at a greater distance from the process. Particularly high levels of ozone are produced when welding aluminum-silicon alloys and pure aluminum.īut ozone does not only escape from the process through the UV radiation outside the arc and thus into the environment, the shiny metallic surfaces of the workpiece itself also reflect the UV radiation. If the amperage is higher, the intensity of the UV radiation also increases. Ozone is formed from a reaction between nitrogen oxide and oxygen with the action of UV radiation produced by the electric arc during welding. The regulations for occupational health and safety TRGS 905 – Technical Rules for Hazardous Substances list of carcinogenic, germ cell mutagenic or reproduction toxic substances – state that ozone is one of the substances classified as carcinogenic. The TIG welding process produces ozone and nitrogen oxide. With the air cooled as well as liquid cooled xFUME ® TIG extraction torches, ABICOR BINZEL has developed fume extraction torches especially for TIG welding, which absorb the welding fumes at the point of origin and thus prevent toxic fumes from being inhaled. This means that invisible welding fumes still exist and must be absorbed and discharged directly at the process before they can enter the ambient air and the respiratory organs. If these are inhaled, serious long-term consequences can occur, such as aluminum silicosis or, in the worst case, cancer in the respiratory tract. However, welding such materials releases toxic welding fume particles that are mostly invisible, but no less dangerous. Materials welded with the TIG process are, for example, stainless steel, also high-alloy stainless steel or aluminum, which look very nice when welded cleanly and evenly. TIG welding is often used for welding work where visual appearance is important in addition to quality. Compared to MIG welding or MAG welding, there is considerably less visible welding fume – but appearances are deceptive: the resulting fumes are mostly invisible, but even more dangerous if they are inhaled. TIG welding is considered an almost fume-free welding process. ![]()
