1. Setting the welding current
2. Display of synergic parameters
Graphical display of the relationship
between the synergic welding parameters:
a. Welding current
b. Wire feed speed (m/min)
c. Arc type
Dip transfer/globular transfer (risk of
weld spatter)/spray transfer
d. Material thickness
1
3. Display of arc length/
shape of welded bead
4. Setting voltage trim
Turn the knob to increase or lower the
voltage. A lower voltage results in a
more focused weld seam with deeper
penetration. A higher voltage results in a
wider weld seam with lower penetration.
5. Display of voltage trim
6. Display of selected program
7. Tack welding
When this function is activated, hotstart,

8. Pulse welding (Sigma One 270)
1
MIG pulse welding on/off.
A constant welding current is present
in DC welding, whereas the current is
switching from a low level to a high level in
pulse welding. This creates a colder melt
bath and reduces the weld spatter. This
process is well-suited for welding in thin
materials.
9. Menu to selection
of welding function
a. Off
b. DUO Plus
(Sigma One 270 Pulse)
DUO Plus pulsating wire (double
TM
pulses) in connection with synergic
MIG, that results in a TIG-like look to the
weld seam. It is possible to adjust the
distance between the droplets.
c. Spot
Welding in defined spot time, that
continues until the torch trigger has
been released.
10. Selecting trigger mode
Change between 2-stroke (indicator off)
and 4-stroke (indicator on).
2-times: The welding process starts when
the torch trigger is activated and ends
when the torch trigger is released.
4-times: The welding process starts
when the torch trigger is activated and
released and ends when the torch trigger
is activated again.
are off. 11. MIGA MEMORY function
TM
Save and easily recall the 5 preferred jobs/
favorite settings.
12. Menu
For setting of secondary parameters and
various other functions e.g. language
selection.
13. Display of welding voltage
Get started
1. Read instruction manual and quickguide prior to initial
operation.
TM
2. Verify that wire feed rolls match the welding task and that
capillary tube and wire guide liner have the same colour
code as the wire feed rolls (see manual):
0.6 mm – white/black
0.8 mm – white
0.9 mm – grey
1.0 mm – blue
1.2 mm – red
U-shaped = aluminum, magnesium and other soft metals
V-shaped = steel and other solid wires
3. Insert the wire in the wire unit and make sure to lock the reel
correctly (see manual).
4. Adjust the wire feed tension according to the wire type.
Wires in aluminum, magnesium and other soft metals
requires less pressure than e.g. steel to be fed without any
problems (see manual).
5. Connect the correct gas bottle to the machine and adjust
gas flow.
6. Turn on the welding machine. Press the -wire inch key
pad in the wire feeder menu or the wire inch knob inside the
wire cabinet to feed the wire into the torch.
We recommend that only the front wire fastener is locked
during wire inching to lower the wire pressure. The back
wire fastener should be locked after finished inching.
7. Select torch type in the torch menu.
8. Select program according to material type, wire dimension,
gas- and wire type. See (2) overleaf.
9. Start welding.
