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
Arc voltage
If necessary, the arc length can be adjusted
by trimming the voltage. The measured
voltage is shown during welding.

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 (FOCUS MIG
27.0 m/min (FOCUS MIG

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.
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 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 - - - .
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.
