AUTOMIG II CONTROL PANEL
Selection of material type
Press the -key pad until the indicator for the
required material is switched on.
Selection of wire dimension
Press the -key pad until the indicator for the
required diameter is switched on.
Not all wire dimensions can be used for all
materials.
Reset to factory settings:
Factory settings for the selected wire dimension will
be reloaded when pressing the key pad until the
indicator gives a short flash.
Current/wire feed speed/material
thickness:
When the machine is not welding, the set
current/ wire feed speed/material dimension
is displayed. During welding the measured
current is displayed.
Material thickness:
The function helps adjusting the current according to
material thickness (in mm). When selecting material
thickness an automatically setting of current is
calculated. Thereafter, the current can be further
adjusted. The material thickness function can be seen
as a good starting point in the selection of correct
current and voltage. A trimming of these parameters
will be required in almost every welding task in order
to obtain the most optimum result.
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 –9,9 to +9,9.
Control knob
This knob is used for adjusting welding
current, wire feed speed, material
thickness, arc length or secondary
parameters. Inching speed is adjustable
during wire inching. Max. wire feed speed is
18.0 m/min.
Setting of secondary parameters
Press the control knob until the requested parameter is
displayed. To return to normal display the key pad for
arc length or current/wire feed speed/material
thickness 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 secs.
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.
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 secs
Remote control
Choose between internal and external adjustment.
0 = internal
1 = torch control
When the machine is switched off, the adjusted parameters
are saved internally in the machine.
Simultaneously, the number of the most recently used
program is saved so that the machine will start up in this.
Please note: Automig
2
i DUO saves the number of the most
recently used program separately for each wire feed unit.
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.
