ADVANCED II control panel
Program selection
Welding programs are selected by a short pressure
on the key pad. A figure is displayed. The figures
indicates a specific welding program.
A welding program is named on the basis of a wire type,
a wire dimension and a gas type.
When the desired program is found through turning the
control knob, press shortly at the key pad and hereby the
program is active.
Reset to factory settings:
Factory settings for the selected program will be reloaded
when pressing the key pad until the indicator gives a
short flash.
Current/wire feed speed/material
thickness/welding program
When the machine is not welding, the set current/
wire feed speed/material dimension is displayed.
During welding the measured current is displayed.
Material thickness:
The function helps adjusting the current according to
material thickness (in mm). When selecting material
thickness an automatically setting of current is calculated.
Thereafter, the current can be further adjusted. The
material thickness function can be seen as a good starting
point in the selection of correct current and voltage. A
trimming of these parameters will be required in almost
every welding task in order to obtain the most optimum
result.
Control knob
Left control knob is used for adjusting welding
current, wire feed speed or material thickness
and inching speed during wire inching.
Right control knob is used fur adjusting arc
length or secondary parameters. Max. wire feed speed is:
18.0 m/min (Omega
2
300)
27.0 m/min (Omega
2
400/550)

Trigger mode
When the indicator is on, 4-times has been
selected and when the indicator is off, 2-times has
been selected. Trigger mode cannot be changed during
welding.
2-times:
Welding starts when the torch trigger is held down. To
end welding, the torch trigger is released and burn back
starts. It is possible to trigger the machine again during
post flow.
4-times:
Welding starts when the torch trigger is held down. The
trigger can then be released and welding continues. To
end welding the torch trigger is held down again and
burn back starts.
Tack welding
The key pad enables change from the actual
welding program to tack welding. Hotstart and
slope-down are not possible to set in tack welding. The
function has its own current value. The trigger mode is
always two-times in tack welding.

DUO Plus
TM
pulsates the wire and enables welding
with ”slow pulse” as seen in many TIG-machines.
This welding method can be seen as a line of partly
overlapping welding spots which results in a characteristic
welding seam similar to a TIG-welding seam.
The advantage with this functions is that the weld pool
is reduced and the penetration ability is increased even
though the welding speed is maintained. The welding
method is a big advantage where there are special
requirements for controlling the weld pool, e.g. when
joining different material thicknesses.
Setting of secondary parameters MIG
Press the control knob until the requested
parameter is displayed. To return to normal display
the key pad for arc length or current/wire feed
speed/material thickness is to be pressed briefly.
Arc adjust:
Arc-adjust (electronic choke) makes it possible to
adjust the speed of reaction to short-circuits. Arc-adjust
can be set in steps from -5.0 to +5.0.
Gas pre-flow:
Gas pre-flow ensures that the arc is fully protected
from atmosphere before an arc is established. Gas pre-
flow time is the time from activating the torch trigger
until the wire feed starts. The gas pre-flow time can be set
between 0.0 sec. and 10.0 sec.
Soft start:
Soft start improves the ignition characteristics. Here
speed with which the wire shall start is set. The speed
is set between 1.5-18.0 m/min. The soft start function is
disengaged when displaying - - - .
Hot-start time:
Hotstart is a function which help creating the right
temperature in the weld pool at the beginning of the
welding.
Hot-start time determines the time in which welding in
hot-start takes place. The time can be set between 0 and
10 secs.
