The storage arm, which can be ordered individually for the left or right side or as a complete set, is an essential accessory for ergonomically optimising the working environment on the laser welding system. The arm is infinitely height-adjustable and can be individually adjusted to the operator's needs thanks to several joints. In addition, the storage arm offers the option of magnetically attaching the joystick to operate the machine so that it is easily accessible from any working position. Alternatively, an armrest cushion can be placed on the storage arm. This not only increases comfort, but also efficiency and precision at work.
