In SYNERGIC MIG welding the welding values are adjusted with power potentiometer (nor-
mally potentiometer for wire feed speed), arc length potentiometers (normally voltage potentio-
meter) and welding dynamics potentiometer. Min. and max. power optimized for each wire
correspond to min. and max. setting of power adjustment potentiometer. Set values connected
with these min. and max. powers are shown in set value displays.
Compensating cable length
By compensation of cable length the voltage losses which arise in long interconnecting cables
and different welding guns are taken into account. Cable compensation is adjusted as follows:
Filler wire .....................Shielding gas

If interconnecting cables between wire feed unit and power
source are not used, set cable compensation at position zero.
If the zero position doesn’t operate as you want to, make
adjustment check as described in following.
When using interconnecting cables, make as follows:
1. Adjust arc length at = CAL, which corresponds to normal arc length
2. Weld at power level wanted by you
3. Adjust with potentiometer for cable compensation a suitable arc length
4. Check adjustment range for arc length by adjusting arc length -9...0...9
5. When needed repeat points 2...4
