PRE-RO
The value expressed in this parameter indicates the current slicing percentage which the
PRE-WELD is carried out with. This parameter is activated through the specific function in the
SETUP MENU.
This parameter is displayed only in FIX WORKING MODE.
PRE-VE
The value expressed in this parameter indicates the value of the secondary voltage which the
PRE-WELD is carried out with. This parameter is activated through the specific function in the
SETUP MENU.
This parameter is displayed only in VEK WORKING MODE.
PRE-POWER
The value expressed in this parameter indicates the value of the secondary power which the
PRE-WELD is carried out with. This parameter is activated through the specific function in the
SETUP MENU.
This parameter is displayed only in PWK or DYN WORKING MODE.
COLD 1
The COLD 1 parameter indicates the time that elapses from the pre-weld. to the weld.
If the pre-weld. is deactivated (that is, when PRE-WELD time = 0), this cold time is not carried
out. This parameter may be activated through the relevant function in the
SETUP MENU
.
SLOPE UP
The current slope up parameter (SLOPE UP) describes the time within which the
programmed value of the weld adjustment parameter is attained. The initial value of this
parameter is equivalent to the minimum value that the adjustment parameter may have if
COLD T. 1 differs from 0. If COLD T. 1 equals 0 and PRE-WELD is other than 0, then the
initial value will no longer be the minimum value of the adjustment parameter but the
adjustment quantity value used in the PRE-WELD..
Whilst the final value is equivalent to the current value programmed in the WELD parameter,
the inclination of the SLOPE UP is calculated automatically by the microprocessor according
to programmed values. The SLOPE UP time is summed up to the welding time.
WELD
The WELD time parameter represents the duration of the passage of the welding current. It
will be carried out according to the work mode selected for the control unit.
When the impulse work mode is activated, this parameter indicates the duration of every
single pulse. This parameter is expressed by four digits since it can be adjusted with a 1 mS
precision.
WELD. MIN.
The minimum weld. time parameter (WELD. MIN.) is expressed in mS and represents the
minimum welding duration. This is carried out with a current value equal to the one indicated
in the CURRENT parameter. The welding operation stops if on the elapsing of said time the
measured energy value is higher than or equal to the corresponding programmed value.
This parameter is displayed only on selecting the ENE WORKING MODE.
WELD. MAX.
The maximum weld. time parameter (WELD. MAX.) is expressed in mS and represents the
maximum welding duration. This is carried out with a power value equal to the one indicated
in the POWER parameter. In any case, the welding operation stops if on the elapsing of said
time the measured energy value is lower than the corresponding programmed value.
This parameter is displayed only on selecting the ENE WORKING MODE.
