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 - - - .
Hot-start time :
Hotstart is a function which help creating the
right temperature in the weld pool at the
beginning of the welding.
Hot-start time determines the time in which welding in
hot-start takes place. The time can be set between 0
and 10 secs
Slope-down:
The time of the current slope-down is set. By
activating the trigger, the slope down begins in
order to make a crater filling. The current reduces from
the adjusted current to stop amp.
In 4-times the welding after current slope-down can be
extended by triggering the torch trigger continuously.
Slope down can be adjusted between 0 and 10 sec.
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.

DUO Plus Efficiency:
When DUO Plus
switched on), it is possible to adjust the
efficiency of the DUO Plus
can be adjusted from 0 to 50 %.
The adjusted parameters are saved internally in the
machine when the machine is turned off.
Simultaneously, the number of the program in use is
saved so the machine will start up in this.
Welding voltage indicator
The welding voltage indicator is illuminated for
reasons of safety and in order to show if there
is voltage at the electrode or torch.
Temperature fault
The indicator is switched on, when the power
source is overheated.
