MAINTENANCE AND USE MANUAL
Fig. 11: position the work (X) on the refractory platform.
When welding pieces of a consistent
mass it is recommended that you
pre-heat in an oven at 400-500°C (for
about 10 minutes) on a ceramic fixing
platform.
Fig. 12: Shift the mechanical pointer (6) towards its
guide limit stop so that it is in line with the central
vertical axis of the surface working plate. at this point it
corresponds to the optimum thermal focussing point
and is in the exact position in which the welding joint
needs to be positioned.
Fig. 13: Use the joystick (3) to position the welding joint
at the thermal focussing point indicated by the
mechanical pointer. the joystick can be used to raise,
lower and rotate the mobile support (13).
Position the welding join with the utmost care and attention. It must be
precisely underneath the mechanical pointer: rotate the platform to check for
proper centring.
Fig. 14: Return the mechanical pointer (6) to its "home"
position at the guide start point.
If the mechanical pointer is not in its
"home" position the safety system will
prevent the welder from being switched
on.
