ALUMINIUM TU-95
The ALUMINIUM TU-95 protects itself if the voltage exceeds 265V. The device prevents the charge of the
capacitors. To indi- cate the failure, the 3 horizontal segments in the centre of the display light up.
Charge of the capacitors: A blinking display indicates that the ALUMINIUM TU-95 is charging the
capacitors to the setpoint. 'DEF' indicates that there is a capacitors charge fault. Switch off and relight the
machine. If the message persists, please contact after sales service department.
OPERATING AND SETTING
The ALUMINIUM TU-95 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 capacitors have a capacity of 53 milliFarads.
Gun cable output (Fig. I-1) Earth cable output (Fig. I-2)
The front panel has a keyboard with 4 keys and a LED display (Fig. II). This device is equipped with:
- 1 earth cable (Length 3m – Ø 35mm²) with 3 brass terminals for earth contact on the car body.
- 1 pistol with a cable (length 3m - Ø 25 mm ²) to weld Ø 4 studs - M4: Alu magnesium (AlMg3), Alu
silicon (AlSi12).
When switching on the product, an error message may come up indicating that the trigger has remain
depressed. Either the trigger has stuck or it may be in short-circuit.
- In the first case, simply release it and resume use.
- In the second case, the product will require return the manufacturer for service.
OPERATION
The ALUMINIUM TU-95 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 ALUMINIUM TU-95 welds M4 studs using capacitor discharge technology. The welding is very fast
(2 to 3 milliseconds). The ALUMINIUM TU-95 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:
- Switching from voltage mode to power mode is done by pressing the 'mode' key (Cf. Fig II-4). See table -
- Power vs Voltage (Cf. Fig. III).
- Press the on/off switch on the right of the keyboard (Cf. Fig. II-6).
- Notice: the earth adapter is factory mounted
- Grind the area which needs to be straightened, such that the 3 brass pads can make the ground contact with
the aluminium car body.
- Position the stud in the copper tip of the gun. Adjust if necessary the screw adjustment of bumper stud (see
pictures below)
- In order to get a good welding of the stud, the base must come out by approximately 1mm from the
extremity of the mandrel (7)
- The position of the stud in the mandrel can be adjusted by screwing / unscrewing the nut on the adjustment
screw (8)
Upon delivery of the gun, the screw 10 is loosened and the cursor 0 is in abutment. This setting allows
exerting a force of about 40 N during welding, which is suitable for welding aluminium studs M4. The
