8 Internal cables and compressed air lines
Internal cables (3BC: 14 wires, 8 x 0.20 mm², 2 x 0.75mm², and 4 x 1.25 mm²) and air hoses
are used in order to use peripheral devices (e.g. gripper). They are mounted on the upper
arm as shown in the following diagram "Connector for internal cables and compressed air
lines".
The pins 1 to 16 are assigned as shown in the following figure. Wiring must be performed
by the user.
The following requirements must be met:
•
The total current value for the internal wiring harness must be 40 A .
• The current-carrying capacity per single conductor (cross-section 0.20 mm², 0.75 mm²,
and 1.25 mm²) must not exceed 3 A or less .
• The air pressure for the air hose must not exceed 600 kPA (the inner diameter of the air
hose is Ø 6.5 and Ø 8 mm).
• For the power cable when arc welding the nominal current may not exceed 350A. In
permanent operation the current may not exceed 60% of the nominal current
(permissible current at permanent operation = 60% x (350A/operating current)²).
