Tochange the spot diameter,the white lever must be slid up and
down. The smallest size of the spot diameter is the slider position
towards the machine. If the slider will be set towards the operator,
the spot diameter will be the biggest.
MANUAL PRIMING OF THE PUMP
In stand-by mode ONLY it’s possible to activate the pump making the water running in the circuit without starting the machine. This
operation is useful when tank is refilled after a full draining or in the first start up of the machine. Release the rotary to stop the pump work.
Press the rotary switch for 3 seconds, triggering the pump that turns
the water in the hydraulic circuit.
Accessory functions
Use of the air dispenser/shielding gas
All devices are equipped with:
1. A pipe jointed to the orientation of the air or protective gas.
2. Metal cone for protective gas coaxial flow.
3. Metal frame holding a protective glass.
If you wish, you can use one system or the other for the supply of shielding gas or air cooling.
The output of the gas / air is controlled by a solenoid valve, which is activated by depressingthe pedal every first frequency shot chain.
The inlet pressure must not exceed 4 bar. Do not connect pressure higher than the maximum allowed as this may damage the solenoid valve.
Example of use of the door slide door with cone:
This configuration is recommended for welding titanium, cobalt
chromium and steels in general.
The recommended pressure for use with protective gas (argon) is
0.1 / 0.2 bar, a soft blow is sufficient for the protection of articles
made of titanium, cobalt chromium and steels in general. Use the
special transparent cone inserted in the cone holder for conveying
the flow at the point of welding, as shown in Figure 1
Example of use of the slide door without dispenser:
This configuration is recommended for welding of objects in Silver
or Gold. It’s also advisable to connect compressed air (up to 4 bar)
to cool the metal during welding prolonged.

Maintenance
Please read the chapter on Safety Information before proceeding
Every maintenance operation, even minor ones for machine parts and the electrical system, requires the use of professionally
qualified personnel with training on the featuresof the device.
Original spare parts should be used. The use of non-original spare parts releasesthe Manufacturer from any liability.
Regular inspections
Check the integrity of the laser radiation safety glass on the KG3 viewing window and the leather curtains for hand access to the welding
chamber daily; if they need to be replaced, contact the manufacturer. Using the device with broken glass or without the curtains is DANGEROUS
and can cause health damage. Check the status and the integrity of the safety labels and IDplate every six months, contact the manufacturer if
they are discolored or illegible.
Checking the coolants
The equipment is provided of a cooling system working with bi-distilled water. The water shall be replaced at least every 12 months to avoid
having algae or limestone, which along time may deposit in the cooling pipes or in the LASER pool cavity.
Open up the rear pipes seat and pull out the 2 pipe caps. Pour the water (around 2 lts) into a basin.
Checking the filters
Air filter must be checked every month. Refer to ”routine maintenance” chapter for more ifnormation
Checking the protective glass slide
Verify at least once in a month the state of the glass placed inside of the welding chamber.
Routine Maintenance
Removal of the liquid
Pull the small pipe located underneath the LASERbase,remove the cap (see picture);place the basin under the opened pipe andwait the water
tank to be fully emptied (around 2 lts).

Filling/refilling the liquid
Use the syringe provided as a standard accessory with the equipment. Insert the syringe with double distilled water into one of pipes (any pipe)
and fill up to the level indicated on the panel. The equipment holds roughly 800ml of bi-distilled water. If overfilled the water will drain out from
the other pipe
Before closing the rear panel, verify the presence of the stoppers on the 2 small tubes.
Cleaning the filters
Failure to maintain these filters can impair the device's performance.
Do not cover the vents on the device with cloth or other materials. Leave at least 10 centimeters of space between the v e n ts and
walls or obstacles. Failure to do so may compromise the efficiency of the device.
Do not cover any of the exhausting grids with clothes or other things and leave enough space (at least 10cm) from the rear grid and
the wall..
Cleaning of air filter
Unscrew the 4 screws shown in the photo. Clean up the filter with compressed air.
Replace the filter when it is very dirty;replace with a filter of the same type (Code RIC00041).
Replace regularly this filter because when full of dust and dirt may compromise the proper
functioning of the equipment.
Replacing the protective glass slide
Verify at least once in a month the state of the glass placed inside of the room (see photo).
To remove the door glass, unscrew the 2 screws indicated in the figure. In case the glass is
saturated of metal sprays or damaged, replace it with one new (Code ATE00018). 1 - Check
also the black paper (Code D2139193) cone inside the plastic light diffuser, to get the best
performance of the illumination this paper must be in good condition, replace it when
necessary.
If the glass is very dirt or damaged, the power of the equipment can go down until to 80% regarding the normal performances.
Checking alignment
•Set the following parameters 1.0KW, 1.0mS 0Hz and minimum SPOT size.
•Insert a piece of flat metal and fire a shot.
•Check the location of the spot produced against the crosshair; if the spot intersects the crosshair in the center is not necessary to correct the
alignment.

Correcting the alignment
Take great care to avoid inadvertently activating laser emission when performing realignment operations.
With the device in standby, locate the screws close to the cone
slide holder as shown in the illustration.
Never touch the screw no. 3, the one between the other two
screws without a guide. This screw has been placed there by the
manufacturer. Using the 3 mm hex key, loosen screws 1 and 2.
•Turning screw no. 1 moves the welding point
horizontally.
•Turning screw no. 2 moves the welding point
vertically.
Use slight movements and small shots on a piece of metal to
verify the correct positioning of the crosshairs. Continue until the
crosshairs coincide perfectly with the welding spot.
The screws for the alignment have brass guides to make them
easier to identify.
To facilitate the alignment procedure, the crosshairs bear the symbol ▲, which indicates the highest point. make sure th is
symbol is pointed upwards and complete the alignment as described above.
Only use the viewing window to inspect the inside of the welding chamber, it is a good rule to put the device in standby before
adjusting the screws to preventaccidentally activating the laser.
