– WORK PROGRAM PARAMETERS DESCRIPTION
All the following parameters that indicate non-weld times are expressed in periods, also called
mains cycles. The mains frequency determines the duration of a period:
Mains frequency 50 Hz - 1 period = 20 ms
Mains frequency 60 Hz - 1 period = 16.6 ms
WORKING MODE
The WORKING MODE parameter defines the program's welding current type of adjustments:
by current slicing percentage (
FIX
), by constant current (
IK
), by constant energy (
ENE
), by
constant power (
PWK
), by constant secondary voltage (
VEK
) and by DYNAMIC MODE
(
DYN
).
The foregoing modes affect the adjustments of the welding current, the secondary voltage
and the current slicing percentage of the inverter. The different adjustment modes affect the
welding blocks relevant to the welding, welding 2, pre welding and post welding.
The possibility of selecting a specific work mode depends on the configuration of the TE700 +
INVERTER units and on the configuration of the spot welder on which they are installed.
CONTROL MODE
This parameter allows the operator to select the control mode of the required weld parameter:
NO
No control is carried out on the parameters of the run weld.
CUR
The welding current min. and max. limits may be set.
RO
The operator may set the minimum and maximum limits of the inverter current slicing
percentage when the weld is executed.
VE
The operator may set the minimum and maximum limits of the average secondary
voltage RMS. The comparison is carried out when the secondary voltage is present during
the WELDING block. If working in pulse mode, the comparison is carried out on the last
run impulse.
PW
The operator may set the minimum and maximum limits of the average supplied
power value. The comparison is carried out with the average power value supplied during
the WELDING block. If working in pulse mode, the comparison is carried out on the last
run pulse.
ENE
The operator may set the minimum and maximum limits of the supplied energy value.
The comparison is carried out with the value of the energy supplied by the inverter during
the WELDING block. If working in pulse mode, the comparison is carried out on the last
run pulse.
The possibility of using a specific control mode depends on the configuration of the TE700 +
INVERTER units and on the configuration of the spot welder which they are installed on.
Moreover, the available control modes depend on the currently selected WORKING MODE.
QUALITY-T
This parameter allows the operator to select if and which controls are to be carried out on the
mechanical qualities of the welded material. The controls are carried out before the passage
of the welding current in order to measure the initial thickness of the material to be welded
and after the passage of the welding current to measure the electrode penetrations inside the
material to be welded.
OFF
No control is carried out on the mechanical dimensions of the material present
between the electrodes.
THICK
The thickness of the material to be welded is measured, before the passage of
the welding current, at the end of the SQUEEZE 1 and SQUEEZE times (if present).
The minimum and maximum limits may be set in the measurement carried out.
