The T-Flex/CW is a wall-mounted telescopic extraction arm with a rotatable hood. Incorporated into the hood is a throttle to control airflow at hood opening. The extraction arm is based on a telescopic tube with counterweight mechanism, allowing it to be extended to give a 2,5 m working radius. The arm is fitted with a spring balance which enables easy movement from a vertical to a horizontal position. This makes the arm is very suitable for welding booths in welding schools where horizontal positions are practiced on the workbench and other welding positions on a support.
