Voltage steps ”Fine”
The arc voltage is increased in fine steps by pressing
the key pad.
The arc voltage is shown in the display if voltage
display has been selected.
Voltage steps ”Rough”
The arc voltage is increased in rough steps by
pressing the key pad.
The arc voltage is shown in the display if voltage
display has been selected.
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.
Wire feed speed
When the machine is not welding, the set wire feed
speed is displayed. During welding the measured
current is displayed.
Control knob
This knob is used for adjusting wire feed speed,
arc voltage or secondary parameters. Inching
speed is adjustable during wire inching.
Max. wire feed speed is:
18.0 m/min (Omega
2
300)
27.0 m/min (Omega
2
400)
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.

Arc voltage
If necessary, the arc length can be adjusted by trimming the
voltage. The measured voltage is shown during welding. Press
the -key pad and adjust from:
13 to 32V (Omega
2
300)
13 to 37V (Omega
2
400)
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
voltage or wire feed speed 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 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 - - - .
Burn back:
The burn back function prevents the welding wire sticking
to the workpiece at the end of a weld. Burn back can be
adjusted between 1 and 30.
Gas post-flow:
Gas post-flow time ensures protection of the molten pool
after welding and cools off the torch. The gas post-flow time is
the time from which the arc extinguishes to the gas flow being
disconnected. The time can be set between 0.0 and 10.0 sec.
Connection/disconnection of water cooling:
The water cooling function will ensure protection
of the watercooled torch. Water cooling will be activated
automatically when welding starts and deactivated
automatically five minutes after welding has stopped.
To activate/deactivate cooling, press and hold down the
4-stroke key while turning the control knob for secondary
parameters.
0 = water cooling disconnected
1 = water cooling connected
Remote control:
Choose between internal and external adjustment.
0 = internal
1 = torch control
2 = remote control
The adjusted parameters are saved internally in the machine
when the machine is turned off.
Welding voltage indicator
The welding voltage indicator is illuminated for reasons of
safety and in order to show if there is voltage at the torch.
Temperature fault
The indicator is switched on, when the power source is
overheated.
