CURR. MAX
The parameter indicates the maximum current that can circulate on the secondary circuit
when the unit's adjustment mode is not by constant current. The task of this parameter is to
protect the integrity of the tool used against excessive increases in the welding current.
The set value must be greater than the value of the welding current that usually circulates in
the machine's secondary circuit with a typical welding performed with a certain spot welder in
its work cycle.
This parameter is displayed only on selecting the VEK, PWK or DYN WORKING MODE.
CURRENT
The value expressed in this parameter indicates the current which the WELD is carried out
with.
This parameter is displayed only in the IK or ENE WORKING MODE.
RO
The value expressed in this parameter indicates the current slicing percentage which the
WELD is carried out with.
This parameter is displayed only in the FIX WORKING MODE.
VE
The value expressed in this parameter indicates the value of the secondary voltage which the
WELD is carried out with.
This parameter is displayed only in the VEK WORKING MODE.
POWER
The value expressed in this parameter indicates the value of the secondary power which the
WELD is carried out with. This parameter is displayed only in the PWK or DYN WORKING
MODE
ENERGY
This parameter indicates the energy value, expressed in joules, which must be developed
during welding. This rating must be reached in a number of cycles between the minimum time
and the maximum time.
This parameter is only displayed when ENE (Constant Energy WORKING MODE) is selected.
IMPULSE N.
The number of impulses parameter (IMPULSE N.) indicates the number of impulses which the
weld is carried out with. The duration time of every single impulse is the one set in the weld.
time parameter (WELD). This parameter is not visible if it is selected as DYN WORKING
MODE.
COLD 2
The COLD 2 parameter is used in the pulse working mode; it indicates the time that elapses
from a welding impulse to the next one.
When the number of the impulses is programmed to zero, cold 2 time is carried out only if a
WELD 2 is programmed afterwards, otherwise it is not carried out. This parameter is not
visible if it is selected as DYN WORKING MODE.
WELD 2
The WELD 2 time parameter represents the duration of the passage of the welding current.
This is carried out conforming to the working mode selected for the control unit. This
parameter is expressed by four digits since it can be adjusted with a 1 mS precision. This
parameter is not visible if it is selected as DYN WORKING MODE. This parameter is activated
through the specific function in the
SETUP MENU.
