ADVANCED II CONTROL PANEL
This control unit contains the possibility of selecting a
MMA-program (electrode welding)
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:
15.0 m/min (Omega
2
220/300)
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
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 1.5-15.0 m/min. The soft start
function is disengaged when displaying - - - .
