7 Main adjustment handle.
Allows wire speed adjustment in manual MIG welding
and synergy correction in synergic MIG welding .
8 Welding methods
2 Stages
In two stages, pressing the button causes the gas to flow,
feeds voltage to the wire and makes it advance; when
it is released, the gas, the voltage and the wire feed are
turned off.
4 Stages
In four stages first pressure on the button causes the gas
to flow with a manual pre-gas time; releasing it activates
the voltage to the wire and its feed.
The following pressure on the button stops the wire and
causes the final process to start which brings the current
back to zero; finally releasing the button turns off the
gas flow.
Wire feed
Allows the manual wire feed without gas flow and with-
out the wire live.
Allows the insertion of the wire into the torch sheath
during the welding preparation phases.
9 Synergy
Allows selection of the manual MIG or synergic MIG
process by setting the type of material to be weld-
ed.
Manual MIG process.
Synergic MIG process, welding of carbon steel.
Synergic MIG process, welding of stainless steel.
Synergic MIG process, welding of aluminium.
10 Wire diameter
In synergy, allows selection of the wire diameter used
(mm).
3.2.1 Set up
Permits set up and adjustment of a series of additional param-
eters for improved and more accurate control of the welding
system.
The parameters present at set up are organised in relation to the
welding process selected and have a numerical code.
Entry to set up: by pressing the encoder key for 2 sec. (the
central zero on the 7-segment display confirms entry).
Selection and adjustment of the required parameter: by
turning the encoder until displaying the numerical code relating
to that parameter. If the encoder key is pressed at this point,
the value set for the parameter selected can be displayed and
adjusted.
Exit from set up: to quit the "adjustment" section, press the
encoder again.
To exit the set up, go to parameter "O" (save and quit) and press
the encoder.
List of set up parameters
0 Save and quit
Allows you to save the changes and quit the set up.
1 Reset
Allows you to reset all the parameters to the default
values.
90 Reset XE (Easy Mode)
It allows manual MIG welding with the adjustment of
the motor slope.
91 Reset XA (Advanced Mode)
It allows manual MIG and synergic MIG.
“STANDARD “synergic control entails automatic pre-
setting of the ideal welding parameters according to the
selected position.
The settings are maintained during the different welding
stages.
The synergic value can be corrected as a percentage
according to the welder’s requirements.
92 Reset XP (Professional Mode)
It allows manual MIG and synergic MIG).
“INTERACTIVE “synergic control entails automatic pre-
setting of the ideal welding parameters according to the
selected position.
Synergic control stays active during the different weld-
ing stages. The welding parameters are constantly con-
trolled and, if necessary, corrected according to precise
analysis of the electric arc!
The synergic value can be corrected as a percentage
according to the welder’s requirements.
99 Reset
Allows you to re-set all the parameters to the default
values and restore the whole system to the conditions
predefined by Selco.
90 Reset XE (Easy Mode)
0 Save and quit
Allows you to save the changes and quit the set up.
1 Reset
Allows you to reset all the parameters to the default
values.
5 Motor ramp
Allows you to set a gradual transition between the
sparking wire speed and the welding wire speed.
Minimum off, Maximum 2.0s, Default 250ms
18 Burn back
Permits adjustment of the wire burn time, preventing
sticking at the end of welding.
Permits adjustment of the length.
