IMPROPER USE
It is dangerous to use the spot-welder for any other purpose than that for
which it is designed (spot resistance welding).
PROTECTIONS
The safeguards and moveable parts of the spot-welder casing should all be in
position before connection to the power supply.
WARNING: All manual operations on moveable accessible parts of the spot
welder, for example:
- Electrode replacement or maintenance
- Adjusting the position of the arms or electrodes
SHOULD BE CARRIED OUT WITH THE SPOT-WELDER SWITCHED OFF AND
DISCONNECTED FROM THE POWER SUPPLY.
2. INTRODUCTION AND GENERAL DESCRIPTION
Mobile system for resistance welding ("spot welder") with microprocessor digital
control.
This manual refers to two system versions in relation to their maximum output current:
3kA or 2.5kA (see technical information plate).
The machine can be used to carry out numerous specific operations in the car
bodywork sector, or other similar sectors (hot sheet working, spot working, etc.)
2.1 MAIN CHARACTERISTICS
Model 3kA:
- Automatic welding parameters selection;
- Quick couplings for the welding cables;
- Automatic detection of the inserted tool:

bodywork.
- Line overcurrent limitation at input (cos input check).
Model 2.5kA:
- "Studder" gun connected permanently to the machine;
- Choice of five different spot welding systems;
- Multilevel adjustment of the spot welding energy;
- Line overcurrent limitation at input (cos input check).

3. TECHNICAL DATA
3.1 RATING PLATE (FIG. A)
The main data relating to use and performance of the spot-welder are summarised on
the rating plate and have the following meanings:
1- Number of phases and frequency of power supply.
2- Power supply voltage.
3- Rated mains power with 50% duty cycle.
4- Mains power with permanent running (100%)
5- Maximum loadless voltage over electrodes.
6- Maximum current when electrodes are shorted.
7- Safety symbols, the meaning of which is given in chapter 1 "General safety rules for
resistance welding".
8- Current to secondary when running permanently (100%).
Note: The rating plate shown is an example to show the meaning of the symbols and
numbers; the exact values of the technical properties of your spot-welder can be found
on the rating plate of the spot-welder itself.

1- Spot-welding time key
limits, of spot-welding time with respect to the preset (factory default) value.
2- "Thickness" key
: used to select the thickness of the sheet to be spot-
welded.
3- Key for selecting functions with the studder gun:
This only has any meaning when the studder kit is used:
: Spot welding: pins, rivets, washers, special washers using suitable
electrodes.
2
: Spot-welding Ø 4mm screws using a suitable electrode.
3
: Spot-welding Ø 5-6mm screws and Ø 5mm rivets using a suitable
electrode.
4
: Spot-welding single spots using a suitable electrode.
5
: Tempering sheet metal using a carbon electrode. Upsetting sheet
metal using a suitable electrode.
6
: Jogged spot-welding for patching sheet using a suitable electrode.
The spot-welder automatically adjusts the welding time according to the chosen
sheet thickness.
4- LED's for selection of tool being used
