(2) Through-arm cable management system
Torch cable and wire through the hollow shaft
(+) Small interior due to outside lying cables
(+) Ideal for offline programming
(-) Problematic wire management
(3) Separate cable Management
Torch cables through-arm wire lying outside
(+) Big and therefore good wire curvature
(+) Low interior due to reduced cable weight
