5.11.2 Aligning the cable resistance

The resistance value of cables can either be set directly or it can be aligned using the power source. The
factory setting of the power sources is 8 mΩ. This value correponds to a 5 m earth cable, a 1.5 m inter-
mediate hose package and a 3 m water-cooled welding torch. With other hose package lengths, it is ne-
cessary to carry out a +/- voltage correction to optimise welding properties. The voltage correction value
can be set close to zero by means of realigning the cable resistance. It is recommended to align the
electric cable resistance after replacing accessories such as torches or intermediate hose packages.
In case a second wire feeder is used the (rL2) parameter has to be aligned. For all other configurations it
is sufficient to align the (rL1) parameter.
