Mobile resistance welding system (spot welding machine). The system can perform
automobile body shop sector and those with similar processing of sheet metal.
Their main characteristics are:
- rapid and intuitive selection of the spot welding program using a potentiometer;
The spot welding machine can work on sheet metal in iron with low carbon content or
on sheet metal in zinc-plated iron.
- Studder gun with trigger.
- Earth cable with earth to spot weld.
- Extractor with blowback.
- Electrode for star washers.
- Star washers for traction.
For further details please consult the latest catalogue.
- Consumables box.
- Trolley.
- Various tools for traction.
For other accessories please consult the latest catalogue.
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.

It allows you to select the welding program based on the tool used.
It signals intervention of a thermostatic safeguard.
It signals the machine is powered.
This is triggered by overheating of the spot welding machine due to low capacity
permitted.
The intervention is signalled by a YELLOW LED switching on (Fig. C-2).
OFF AND DISCONNECTED FROM THE MAINS BEFORE COMMENCING
Unpack the spot welding machine and assemble the separate parts included in the
package (if present).
WARNING: None of the spot-welders described in this handbook have lifting devices.
Reserve a space in the installation area that is large enough and without obstacles
for guaranteeing access to the control panel, the main switch and the work area in
complete safety.
Make sure there are no obstacles near the areas where the cooling air enters and exits,
ensuring that conductive power, corrosive vapour, humidity, etc. cannot be sucked in.
compact, and suitable for supporting the weight (see "technical data") to prevent the
danger of toppling or dangerous movements.
Before making any electrical connection, make sure the spot welding machine plate
data correspond with the mains voltage and frequency available in the installation
area.
The spot welding machine must only be connected to a power supply system with
neutral conductor connected to earth.
To guarantee protection against indirect contact, use residual-current devices of the
following type:
- Type A (
- Type B (
- The spot welding machine does not meet the requirements of the IEC/EN 61000-
3-12 directive.
If it is connected to a public power grid, the installer or user must make sure that
the welding machine can be connected (if necessary consult the utility company).
The power supply cable is supplied with a Schuko (2 poles + earth) plug already
assembled.
Connect a standard plug (3P + E: only 2 poles are used: INTERPHASE connection!)
to the power supply cable of adequate capacity.
Prepare a mains socket protected with fuses or an automatic circuit breaker switch;
power supply line.
The capacity and characteristics of fuse and circuit breaker switch intervention are
outlined in the "TECHNICAL DATA" paragraph.
If multiple spot welding machines are used, distribute the power supply cyclically
400V ~ 2ph-50/60 Hz between the three phases to create a more balanced load; for example:
spot welding machine 1: power supply L1-L2;
230V ~ 1ph-50/60 Hz
I spot welding machine 2: power supply L2-L3;
spot welding machine 3: power supply L3-L1.

The parameters that intervene to determine the diameter (section) and the mechanical

- Force exercised by the electrode.
- Spot welding current.
- Spot welding time.

The current and time parameters of spot welding are adjusted using the potentiometer
(Fig. C-1):
- turn the knob according to the tool you intend using;
- turning clockwise, you obtain longer spot welding times;
- the longer cycle is obtained for the "sheet metal recalculation" tool
