Basic settings and displays (2, 3, 4, 5)
With MIG welding, the wire feed speed is set via potentiometer No. 2, the value of which is shown
on display No. 4. The welding voltage is set via potentiometer No. 3, the value of which is shown on
display No. 5. During welding, display 4 shows the actual welding current value and display 5 shows
the welding voltage.
With electrode welding (MMA), the welding current value is set via the potentiometer, the value of which
is shown on display No. 4. Potentiometer 5 is not in use with electrode welding. Display 5 shows the
idling voltage of the power source during adjustment of the value set for the current. During welding,
display 4 shows the actual welding current value and display 5 shows the welding voltage.
When MIG dynamics/electrode welding Arc force adjustment is activated via button No. 7, the value is
adjusted via potentiometer No. 3 (see the information on adjustment of MIG dynamics/arc force).
With Synergic 1-MIG welding, the power value is set via potentiometer 2 and the length of the arc via
potentiometer 3 (see '1-MIG welding').
When the adjustment of SETUP parameters has been confirmed with 6 long button presses, the
adjustable parameter is selected via potentiometer No. 2, the name of which is shown on display
No. 4. The parameter's value is set via potentiometer No. 3, the value of which is shown on display
No. 5 (see 'SETUP functions').
Selection of MIG operating procedure (6)
MIG 2T: MIG welding with two-sequence procedure of welding gun start switch
1. switch pressed: welding starts
2. switch released: welding stops
MIG 4T: MIG welding with four-sequence procedure of welding gun start switch
1. switch pressed: shielding gas flow starts
2. switch released: welding starts
3. switch pressed: welding stops
4. switch released: shielding gas flow stops
Adjustment of MIG dynamics/Arc Force (7)
With MIG welding dynamics adjustment is influenced on welding stability and spatter amount. Zero
setting is recommended basic setting. Values –> min (-1...-9), softer arc for reduced spatter amount.
Values –> max (1...9), harder arc for increased stability and when 100 % CO ² shielding gas is used
in welding of steel.
With electrode welding Arc Force adjustment is influenced on welding stability. Adjustment is needed
for using different types of electrodes. Control range (-9...0) is commonly used for welding electrodes
for stainless steel. Control range (0...+9) is used for harder arc characteristic to increase stability,
e.g. for welding with thicker basic electrodes and using lower current value than recommendated.
Factory set value (0) is a good general use for adjusting the roughness of the arc.
Gas test (8)
The gas test button opens the gas valve without activating the wire feed or power source. Gas
flows for 20 seconds by default. The display shows the remaining gas flow time. The default time
of gas flow can be adjusted via the right-hand potentiometer within a range of 10 to 60 seconds.
The new time setting is recorded in the memory. The gas flow can be discontinued by pressing the
ON/OFF button or the start switch of the gun.
Wire feed test (9)
The wire feed switch starts the wire feed motor without opening the gas valve and without engaging
the power source. The default wire feed speed is 5 m/min. The speed can be adjusted via the
right-hand potentiometer. When the button is released, the wire feed stops. Operation returns to
normal approx. 3 seconds after release of the button or if the ON/OFF button is pressed briefly.
Selection of liquid- /gas-cooled MIG gun (11)
Selection of liquid-cooled/gas-cooled MIG gun is activated by pressing buttons 7 and 8
simultaneously (for more than 1 second). When 'Gas' is shown on the display, the welding equipment
will assume that a gas-cooled MIG gun has been connected. If the above buttons are pressed again,
the text 'COO Ler' appears on the display and the LED (12) indicating liquid cooling selection
lights up. In this case, the welding equipment will assume that a liquid-cooled MIG gun has been
connected. When liquid cooling has been selected, the liquid cooling unit will start up in connection
with the next equipment start-up.
