OPERATION
The GYSPOT ALU PRO FV was designed to carry out repairs to aluminium car bodies, which have minor dings and dents,
marks, scratches or hail damages.
Short charging times and thus quick welding sequences are accomplished.
The robust construction ensures high reliability and high power-on time.
The GYSPOT ALU PRO FV welds M4 studs using capacitor discharge technology. The welding is very fast (2 to 3
milliseconds).
The GYSPOT ALU PRO FV has 2 operating modes:
-
Voltage programming mode: from 50 to 200 Volt.
-
Power programming mode: L,1-9,H. L means low, H means high:
o
Switching from voltage mode to power mode is done by pressing the ‘mode’ key (Cf. Fig II-
). See table Power vs
Voltage (Cf. Fig. III).
o
Press the on/off switch
on the right of the keyboard (Cf. Fig. II-
).
o
Notice: the earth adapter is factory mounted
o
Grind the area which needs to be straightened, such that the 3 brass pads can make the ground contact with the
aluminium car body.
o
Position the stud in the copper tip of the gun. Adjust if necessary the screw adjustment of bumper stud (see
pictures below)
o
In order to get a good welding of the stud, the base must come out by approximately 1mm from the extremity of
the mandrel (
)
o
The position of the stud in the mandrel can be adjusted by screwing / unscrewing the nut on the adjustment screw
(
)
Upon delivery of the gun, the screw
is loosened and the cursor
is in abutment. This setting allows exerting a force
of about 40 N during welding, which is suitable for welding aluminium studs M4. The screw is used to adjust the down
force of the spring when the shot is fired or to compensate for the wear of the spring.
Adjust the power or the voltage value using + and - buttons. At power up the power value by default is 5 which is 100
volts. In general, the value to have a good welding of a M4 stud for small dent removal is: voltage = 90 V or power = 4.
Increase the voltage for thicker panels. Be careful, too elevated power can damage the copper base.
For a good weld, only the « nipple of the stud » must be in contact with the component.
Make a small pressure on the gun without crushing the “pin” of the stud. The capacitor discharge is done automatically
when the support comes in the ring.
At this moment the stud is correctly welded. Welding duration is less than 3 milliseconds.
For an optimum repair, we advise you to warm up the metal sheet.
The copper base has 4 slots and is dedicated
to M4 studs
Automatic gun without trigger
The base must come out by approximately 1mm from the extremity of the mandrel.
Screw for adjusting the stud’s position.
The pin must be perpendicular to the sheet.
Do not press too much to not overwrite the nipple. Only the stud is in contact with the sheet.
A wheel with index
allows adjusting the compression of the spring.
