IMPORTANT! The Robacta Twin comes with a clamp fitted as standard. clamp/adjusting clip The Robacta clamp and Robacta adjusting clip are for fitting the Robacta hose pack to the robot or to the welding machine. The adjusting clip supports TCP correction on the robot. The Robacta adjusting clip can be adjusted in such a way that the position of the arc is maintained dur- ing a corrective movement by the robot.

IMPORTANT! Drill a Ø5.8 mm hole for the mounting bracket and use a reamer to enlarge the hole so it can accommodate the dowel pin (Ø6G7). IMPORTANT! The mounting bracket must be fitted using an M8 shoulder screw and an M6 screw. After screwing the mounting bracket in place, another dowel pin (Ø6 mm) must bei driven in to secure it.
