BASIC II CONTROL PANEL
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.
Wire feed speed
When the machine is not welding, the wire feed
speed is displayed. During welding the measured
current is displayed
Arc length
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
13-32V
(Omega
2
220/300)
13-37V (Omega
2
400)
13-42V (Omega
2
550)
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 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 1.5-15.0 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.
Gas control
Adjustment of the gas flow is possible if a gas
control kit IGC (Intelligent Gas Control) has been
mounted. The gas flow is variable 0,5 - 27 l/min. The fault
is disconnected by adjusting the manual gas flow to 27
l/min.
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.
