If changing the mains cable take into consideration the following:
The cable is entered into the machine through the inlet ring on the rear panel of the machine and
fastened with a cable clamp (05). The phase conductors of the cable are coupled to connectors
L1, L2 and L3. The earth protection coloured green-yellow is coupled to connector
If you are using 5-lead cable, you must connect neutral conductor with
terminal N.
*) In cables of S type there is a protective grounding conductor coloured green-yellow.
2.2.2. Welding and earth cables
Recommended copper cables with cross-sectional area are as follows:
Kemppi Pro Evolution 3200
50 ... 70 mm 2
Kemppi Pro Evolution 4200 70 ... 90 mm 2
Kemppi Pro Evolution 5200 70 ... 90 mm 2
In enclosed table are shown typical load capacities of rubber insulated copper cables, when
ambient temperature is 25 ºC and lead temperature is 85 ºC.
CABLE DUTY CYCLE ED VOLTAGE LOSS / 10m
...........................100% .........60% ........... 30%

95 mm 2 ..............430 A .........560 A ......... 790 A ...........0,18 V / 100 A
Do not overload welding cables due to voltage losses and heating.
Fasten the earth clamp of the return current cable carefully, preferably direct onto the piece to be
welded. The contact surface of the earth clamp should always be as large as possible.
Clean the fastening surface from paint and rust.

When you turn the switch into I-position, pilot lamp H11 on the front face is illuminated and the
machine is ready for use.
Always turn the machine on and off with the mains switch, never use the
mains plugs as a switch.
