Connection 3~ 230 or 3~ 400 V of mains voltage
By delivery from the factory the Kempomat 3200 and 2500 machine has been connected for
mains voltage 3~ 400 V. In order to change the mains voltage in the Kempomat 2500/3200
machine, remove the side plate of the machine. Change the connections according to the
enclosed diagram. You nd the corresponding wiring diagram on the instruction label, which
is under terminal block.

Don´t overload welding cables over permissible values due to voltage losses and
heating.
Fasten the earthing press of the return current cable carefully, preferably direct
onto the piece to be welded.
The contact surface area of the press should always be as large and steady as pos-
sible. Clean the contact surface from paint and rust.
