WELDING MODE SELECTION
The Welding Analogue Control unit (WAC) allows two
possible control modes:
Constant Current (CC)
Constant Voltage (CV).
The welding option with C.V. characteristic is possible only
on those models which support this mode of operation.
On such models there is a switch which allows to select
the desired mode.
The regulation with C.C. characteristic can be used to
weld with various types of electrodes.
The regulation with C.V. characteristic is suitable for the
wire welding, both naked and coated.

VOLTAGE AND CURRENT REGULATION
Current regulation
When the CC/CV switch is in CC position the main knob
sets the welding current within a range from 20A to
210A.
Voltage regulation
With the CC/CV switch in CV position the main knob
sets the welding voltage in a range between 14V - 44V.
