AUTOMIG CONTROL PANEL
Selection of material type
Press the -key pad until the indicator for the
required material is switched on.
Reset to factory settings:
Factory settings for the selected material type
will be reloaded when pressing the key pad
until the indicator gives a short flash.
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 and secondary
parameters. Max. wire feed speed is
15.0 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 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 - - - .
