F3. Diagram
The actual welding current depends on
several factors: supply voltage, cable
length and cable cross-sectional area are
particularly important.
The diagram represents the main func-
tions and processes graphically.
Cable length
The power unit can supply a maximum of
18 kA. However, such a current is seldom
necessary, and it requires
a cable length
of zero.
For a welding current of 6-8 kA, which is a
normal value for 3+3 steel, 150 mm²
cables can be up to 2 m long. Heavier
currents require shorter or thicker cables.
(The diagram applies for a high mains
voltage and low internal impedance.)
