The full functional range of the PM function torch is only available in connection with the device series Titan XQ and the wire feeder drive XQ. If the function torch is connected to another EWM device series using Multimatrix, the welding torch switches to compatibility mode and is restricted in its functions.
Design and function Settings 5.2.1 Operating elements in the machine This setting affects the torch types 2U/D, and RD2. Figure 5-1 • Switch the"Program or up/down mode“ changeover switch at the welding machine to the up/down or program mode position (see chapter "Design and function"). The 'Program or up/down function' changeover switch may look different on your machine.
