The training center has 18 welding cabins. These welding cabins are used to work on small, flexible work pieces, making it possible to create permanent workstations equipped with source extraction. To give the students as much flexibility as possible within the welding cabins, the choice was made to equip each welding cabin with a T-Flex CW extraction arm. The extraction arm is based on a telescopic tube with counterweight, which gives the arm a working radius of 2.5 m in the extended position. In the retracted position the range is 1.5 m.
