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:
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.
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
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 1.5-18.0 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.
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.
Gas error can be inactivated by setting the manual gas
flow at 27 l/min.
Spot time:
When the spot time function is active, welding will
stop automatically after expiry of the set spot time. It is
possible to stop welding before the spot time expires by
pressing the torch trigger.
If the spot time is altered during welding, the alteration
has no effect till next welding. The spot time is adjustable
between 0.0 and 50.0 seconds. The value 0.0 means that
the function is disconnected.
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
