SLOPE UP
The SLOPE UP parameter describes the time for attaining the programmed welding current
value. The starting value of this slope always corresponds to the minimum current, whereas
the final value corresponds to the current value set at parameter POWER. The SLOPE UP
inclination is automatically calculated by the microprocessor according to the set values. The
SLOPE UP time is added to the welding time.
WELD
The WELD time parameter indicates the welding current flow duration. It is carried out with
the same power value set at parameter POWER.
When the pulse operating mode is activated, this parameter indicates the duration of each
pulse. This parameter is expressed by three digits since it can be adjusted with half-cycle
precision.
WELD MIN
The minimum weld time parameter (WELD MIN) is expressed in cycles and represents the
welding duration minimum time. It is carried out with the same power value set at parameter
POWER. Welding will stop if the energy measured at the end of this period of time is above or
equal to the programmed rating. This parameter is only displayed when ENE (Constant
Energy operating mode) is selected.
WELD MAX
The maximum weld time parameter (WELD MAX) is expressed in cycles and represents the
welding duration maximum time. It is carried out with the same power value set at parameter
POWER. Welding will stop also if the energy measured at the end of this period of time is
below the programmed rating.
This parameter is only displayed when ENE (Constant Energy operating mode) is selected.
POWER
The value expressed in the POWER parameter indicates the power adjustment the welding
process is carried out with.
This parameter is only displayed when either FIX (Power operating mode) or ENE (Constant
Energy operating mode) are selected.
CURRENT
The value indicated in the CURRENT parameter shows the current adjustment used for
carrying out the welding process.
This parameter is only displayed when IK (Constant Current operating mode) is selected.
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 operating mode) is selected.
