1 - Connecting the cables (Fig. D1-D2)
1) Screw the torch to the centralised connection on the front
panel of the welding welding power source (Pos. 4, Fig. A).
2) Connect up the earthing system cable to the rapid cou-
pling marked by a + (positive) symbol and then the relevant
ground clamps to the piece being welded or to its support in
an area free from rust, paint and grease. Using particularly
long earthing cables reduces the voltage and causes some
problems from increased resistance and inductance of the
cables that could cause faulty welding. Follow instructions
to avoid these problems:
•
Use earthing and extension cables with appropriate sec-
tion.
•
Lay out the cables as a flat as possible to prevent them
from coiling up.
3) Open the moving cover, remove the protection box for
changing polarity (see Fig. D2) and move the change po-
larity cable, connecting it to the negative pole (-).
2 - Welding
1) Open the moving cover and fit a coil of wire with a core for
welding without using gas.
2) Load the wire (see the “Loading the wire” paragraph).
3) Switch the welding welding power source on by moving the
power supply switch to
I
(Pos. 5, Fig. A).
4) Carry out the following operations on the MIG-MAG torch:
•
Remove the gas-guide and wire-guide nozzles, allowing
the wire to flow freely during loading. Remember that the
contact tip must correspond to the wire diameter.
•
Push the torch push button or the motor check push but-
ton until the wire end comes out from the torch.
•
Tighten the contact tip on the torch.
•
Attach the correct gas-guide nozzle.
•
Protect the gas-guide nozzle and the wire-guide nozzle
of the torch from sprays of solder.
5) Make the adjustments and select the parameters on the
control panel. Make sure that you have selected a program
that is suitable for wire with a core.
6) The welding welding power source is ready for welding. To
begin welding, approach the point to be welded and press
the button on the torch.
7) Once welding has been completed remove the slag and
switch off the welding power source.
Spot welding
FIG. E
Welding can be done with or without gas. The substantial differ-
ence with MIG-MAG welding is essentially related to the torch
and the adjustments that must be made on the control panel.
•
Depending on the torch chosen and the work to be done, a
gas guide nozzle can be fitted on the torch that is specifical-
ly for spot welding (see Fig. E).
•
Use the control panel to select the spot-welding mode and,
if necessary, make the changes to the related “Special func-
tions - Fx” (for further information see the control panel manu-
al), which allows the welding power source to do this specific
type of welding.
To begin spot welding:
•
Place the gas guiding nozzle perpendicular on the workpiece
to be spot welded.
•
Press the torch button to start the welding current and wire
feed.
•
When the spot welding time expires (SPOT WELD TIME),
the wire feed stops automatically.
•
When the torch button is pushed again a new welding cy-
cle starts.
