* Section for every phase, calculated for PVC insulated, single conductor cables, considering the welder working at
the maximum welding power and a 4% voltage drop on cables.
** Approximate value, calculated for a three phase transformer with a 4% short circuit voltage, with 6% voltage drop
on transformer and a 4% voltage drop on cables, with the welder adjusted for the maximum welding power.
