NOTE: The value shown on the display during welding represents

the effective current output with all types of control.
The digital control unit of the generator is fitted with a control rec-

device to work correctly, connect (with the machine switched off)
the required accessory to the relative connector and then switch
on the welding machine with the on/off switch.
NOTE: It is not possible to memorize or open programmes
when the remote controls are connected (except for the torch

If a remote control is connected (followed by self-acknowledge-

All of this is necessary to allow our technical assistance depart-
ment (which must be contacted each time error messages
appear on the equipment’s operator interface) to resolve prob-
lems more easily, as quickly as possible and thanks to the user’s
reports, also because, in the meantime the machine will not allow
