Spot welding
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.
•
Release the torch button.

Interval welding (Stitch)
The substantial differences with the spot welding mainly con-
cern the adjustments that must be carried on the welding pow-
er source.
Use the control panel to select the interval welding mode and
then make the changes to the related “Special functions - Fx”
(for further information see the control panel manual), which
allows the welding power source to do this specific type of
welding.
To begin interval welding:
•
Press the torch button to start the welding current and wire
feed.
•
At this point the welding power source automatically carries
out a succession of welded portions (STITCH WELD TIME)
followed by a pause (STITCH WELD PAUSE), according to
the times entered previously. This procedure stops automati-
cally only when the TORCH BUTTON is released.
•
When the torch button is pushed again the torch begins a
new interval welding cycle.
Aluminium welding
To weld with aluminium wire proceed as follows:
•
Replace the drive rolls with special ones for aluminium wire.
•
We recommend to use a torch set with a maximum lenght of
3 m and a capillary liner, e.g. DIX DSK 2-xx.
•
Set the pressure between the drive rollers at the minimum,
by turning the screw provided.
•
Use argon gas at a pressure of 1,3 - 1,7 bar and regulate
the flow to a value between 14 and 20 lit/min to suit the cur-
rent used for welding.
Electrode welding (MMA)
On the
DIX PI GO 2006.M / DIX PI GO 2006.M Puls
welding
power source, electrode welding is used to weld most metals
(different types of steel, etc.) using coated rutilic and basic elec-
trodes with diameters ranging from Ø 1.6 mm to Ø 6 mm, and
devices that the user can adjust for “Arc Force”, “Hot Start”, and
Anti-sticking functions to avoid the electrodes sticking.
1) Connecting the welding cables (Fig. F):
Disconnect the welding power source from the mains power
supply and connect the welding cables to the output termi-
nals (Positive and Negative) of the welding power source,
attaching them to the clamp and ground with the polarity
specified for the type of electrode being used (Fig.F). Al-
ways follow the electrode manufacturer’s instructions. The
welding cables must be as short as possible, they must be
near to one another, positioned at or near floor level. Do
not touch the electrode clamp and the ground clamp simul-
taneously.
2) Switch the welding power source on by moving the power
supply switch to I (Pos. 8, Fig. B).
3) Make the adjustments and do the parameter settings on the
control panel (for further information see the control panel
manual).
4) Carry out welding by moving the torch to the workpiece.
Strike the arc (press the electrode quickly against the met-
al and then lift it) to melt the electrode, the coating of which
forms a protective residue. Then continue welding at an in-
clination of about 60° compared with the metal in relation
to the direction of welding.
PART TO BE WELDED
The part to be welded must always be connected to ground
in order to reduce electromagnetic emission. Much attention
must be afforded so that the ground connection of the part to be
welded does not increase the risk of accident to the user or the
risk of damage to other electric welding power source. When
it is necessary to connect the part to be welded to ground, you
should make a direct connection between the part and the
ground shaft. In those countries in which such a connection
is not allowed, connect the part to be welded to ground using
suitable capacitors, in compliance with the national regulations.
