Installing the
contact cams
Straight rails Both rigid and exible straightw rails can easily be extended using the joining elements
supplied.
1. Set the levers on the magnetic bridges (1) to OFF.
2. Place the rail section on the workpiece and set the levers on the magnetic bridges
to ON.
3. Fit the joining element (2) at the end of the straight rail.
4. Loosen both M6 screws (3).
5. On the next section of rail, set the levers on the magnetic bridges to OFF.
6. Push the next section of rail with the groove (4) between the joining element (2)
and the screw (3).
7. Tighten both M6 screws (3).
8. Align the rail if necessary, then set the levers on the magnetic bridges to ON.

quired length.
10. Install a contact cam for the limit switch at the beginning and end of the rail.

IMPORTANT! If contact cams are not used, there is a risk that the welding carriage
might travel beyond the end of the rail and fall off.
In rail structures with open ends (not rings), contact cams (limit switch installation kit)
must be installed at both ends.
