9.2.5 How to align the reticle pointer of the binocular
The reticle pointer may sometimes not be aligned with the actual shot point. This can occur when the welding machine is moved or
lifted.
Impacts with the microscope can also cause misalignments between the reticle pointer and the actual shot point. In any case, these
minor optical defects can be compensated for by performing regulation of the pointer.
First of all, you will need to align the binocular (Fig. 9-2):
•
Loosen the screw holding the binocular in position on its base (use the 2,5 mm hex head wrench supplied with the machine);
•
Push the binocular against the side, in the opposite direction to the frontal position;
•
Fasten the binocular position screw;
•
Calibrate the binocular, by following the instructions provided under paragraph 7.5.1.
Fig. 9-2 – Binocular alignment
To check and - if necessary - correct the alignment of the reticle pointer, please follow the indications below (Fig. 9-3):
•
Place a small piece of sheet metal in the welding chamber, in a stable position and in full visual focus;
•
Shoot a single low pulse at the previously inserted sheet metal;
•
Looking through the microscope, use a 3 mm hex key to turn screws 1 and/or 3 with very small movements, until the reticle
overlaps with the point in which the shot hit the sheet metal.
It is important to operate on one screw at a time as each one causes a distinct movement:
•
Screw 1 controls vertical movements (North-South);
•
Screw 3 controls horizontal movements (East-West).
PROHIBITION!: DO NOT touch screw 2 (which must remain fixed), as this will jeopardize the entire alignment system.
Operate progressively on screws 1 and 3, alternating actions on one and the other as many times as necessary to make sure that the
reticle pointer focused on the object and the shot point coincide perfectly.
