CURRENT 1 (WELDING CURRENT)
The value indicated in CURRENT 1 shows the current adjustment used for carrying out the welding
process.
Depending on the adjustment mode selected by means of the WORK MODE parameter, this value
indicates either the current percent adjustment (PW%, power percent adjustment), or the required
welding current value expressed in kA (IK, constant current adjustment).
N. IMPULSE (NUMBER OF IMPULSES)
The N. IMPULSE parameter indicates the number of impulses used for carrying out the welding
process. The duration of each impulse corresponds to the time set in parameter WELD 1 (WELDING
TIME).
COLD 2 (COLD 2 TIME)
The COLD 2 parameter is used in the pulse operating mode; it indicates the time that elapses from a
welding impulse to the next one.
SLOPE DOWN
The SLOPE DOWN parameter is a welding time that is added at the end of the welding process: it
enables to decrease the welding current from the value set at CURRENT 1 down to the minimum value.
The slope inclination is automatically calculated by the microprocessor according to the set values. The
SLOPE DOWN time is always added to the welding time.
COLD 3 (COLD 3 TIME)
The COLD 3 parameter indicates the time that elapses from the welding process (WELD 1) to the post-
weld (POST-WELD).
POST-WELD
The POST-WELD parameter indicates the duration of a current flow that can be carried out after the
welding time in order to enable a more gradual cooling of the welded workpiece. This parameter is
expressed by three digits since it can be adjusted with half-period precision. If this parameter is set to 0
the post-weld is not carried out. The post-weld is carried out with the current adjustment set in the
POST-POWER parameter.
POST-POWER
The value expressed in this parameter indicates the post-welding power.
HOLD TIME
The HOLD parameter indicates the time that elapses from the end of the welding process to the
opening of the electrodes. It allows a quicker cooling of the welding spot and prevents the spot from
being stimulated before being properly cooled.
OFF TIME (DWELL TIME)
The OFF TIME parameter indicates a welder wait time, namely the one that elapses from one welder
cycle to the next one when the welder is working in automatic cycle. When this value is set to zero, the
welder always works in single cycle; if it is set to another value, the welder will work in the automatic
cycle.
When the welder works in single cycle, the control unit carries out a single welding cycle each time it
receives a start cycle signal. When the welder works in automatic cycle, the welder goes on executing
welding cycles until the start cycle signal is released.
By programming this parameter to 99 the welding current compensation function is activated (see the
relevant paragraph).
