22 – PROMIG 520R, 120R / 0544 © KEMPPI OYCompensating cable lengthCable length compensation allows the operator to overcome voltage losses which are caused bylong interconnecting cables. Cable compensation is adjusted as follows:If interconnecting cables between wire feed unit and powersource are not used, set cable compensation at positionzero.If the zero position does not operate as you want it to, makeadjustment check as described in the following.When using interconnecting cables, do as follows:1. Adjust arc length at = CALIB, which corresponds to normal arc length.2. Weld at power level required.3. Adjust cable compensation potentiometer to give suitable arc length.4. Check adjustment range for arc length by adjusting arc length -9...0...9.5. When needed repeat points 2...4.Cable compensation is adjusted for each cable / MIG welding gun combination only once.Synergic pulsed MIG, pulsed MIG welding with parameters which are optimisedaccording to filler wire parameters.
