APPLICATION
This machine has been designed to repair aluminium bodywork with small dents, scratches or hail damage.
This machine welds M4 and M6 studs by means of capacitor discharge. This occurs as soon as the tip of the gun is
depressed. The weld is very fast (2 to 3 milliseconds).
This machine can be programmed in two different modes:
- Voltage mode: Voltage is programmable between 50 and 200 V.
- Power mode: Power is programmable between L, 1-9, H:
o To switch from one mode to the other, press the mode button (Fig. II-
o Table showing power level and corresponding voltage (Cf. Fig. III).

Description of the Gyspot alu 66 welding process
o Strip the area being repaired in order to ensure that the 3 brass pins can make ground contact with the bodywork.
o Position the stud in the chuck. If necessary, adjust the stud stop adjustment screw (see photos below).
o To ensure a sound weld, the head of the stud should protrude approximately one millimetre from the end cap (
o The position of the stud head is adjusted by turning the nut on the adjusting screw (
For a good weld, only the "nib" of the stud should be in contact with the workpiece.
Apply light pressure to the gun without crushing the stud, keeping the gun perpendicular to the sheet. The capacitors
are discharged automatically as soon as the gun tip is pushed into the ring.
That is when the stud is welded. The duration of the weld is less than 3 milliseconds.
For the best possible straightening performance, we recommend heating the workpiece.
When the gun is first supplied, the adjusting screw
vers a force of around 20N when the gun is activated, which is suitable for welding M4 and M6 aluminium studs. The
screw is used to adjust the force of the spring when the mechanism is triggered, and to compensate for wear.
Set the voltage value using the + and - buttons.
The default power value when the device is switched on is 5, which is equivalent to 100 volts.
In general, the value for a satisfactory weld on a 4 mm diameter stud for dent removal is 90 V. This corresponds to
power level 4.
The value of the voltage required increases according to the thickness of the sheet. Caution: excessive voltage can
damage the surface.

Points counter menu :
A menu automatically counting the number of points completed is available by pressing and holding the Mode but-
ton for 3 seconds. The screen will then flash between "CPt" and the number of points completed. By default, when
the device is launched, this number is zero. It will be incremented by 1 for each spot welded. To reset the number of
points to 0, hold down the "+" and "-" buttons simultaneously for 3 seconds.
When you switch to counter mode, the voltage settings are memorised and will be used for all subsequent stitches.
The counter does not reset to zero each time the product is switched off; it remembers the number of stitches made
until it is reset manually.
