5.5.2

Aligning the cable resistance

The resistance value of the cables can be set directly or it can be adjusted through the power source. The
power source cable resistance value is set to 8

mΩ when delivered. This value corresponds to an earth

cable length of 5 m, an intermediate hose package length of 1.5 m and a water-cooled welding torch
length of 3 m. A +/- welding voltage correction is therefore required to optimise the welding properties for
other hose package lengths. By realigning the cable resistance, the voltage correction value can be set
close to zero again. The electric cable resistance should be realigned whenever an accessory component
such as the welding torch or the intermediate hose package has been changed.
