54 TROUBLESHOOTING, FAULTS AND MAINTENANCE
ALIGNING THE AIMING SIGHT
To adjust the stereo-microscope, unscrew it from its base (Ref. D - Fig.
61), using the 2.5 mm Allen screwdriver provided, and once it has been
pushed firmly against the front edge of its base, or in other words away
from the operator's position, screw it down firmly so it is immobilised
permanently in that position.
Then, in order to check the alignment, place a sheet metal plate inside
the welding chamber so that it is stable and in focus. Next, strike the
metal plate with a single, low-power shot.
Now, looking inside the microscope, rotate the screws 1 and/or 3 by
very small amounts (figure 61) until the aiming sight coincides with the
point where the laser shot struck the metal plate. It is important to move
only one screw at a time since they both have a distinct displacement
effect. In fact, screw 1, is used for vertical (or north-south) adjustments,
while screw 3 corrects horizontal (or east-west) displacements. Screw
2 remains fixed and must never be touched, otherwise the entire
alignment system may be compromised.
Act progressively on these screws, alternating between one and the
other and as many times as necessary to ensure both (the aiming sight
used to focus on the object and the firing focus point) coincide perfectly,
or are virtually and precisely superimposed.

ATTENTION: During the alignment phases, make sure that hands are positioned where they do
not interfere with the passage of the LASER.
ATTENTION: When adjusting the alignment, always use very small movements and ensure
that the test plate remains perfectly stable. NEVER UNDO THE REGULATOR SCREWS
COMPLETELY.
