HOLD TIME
The HOLD TIME 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
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.
CURR. MIN
This parameter fixes a minimum current limit value. For each weld, the control unit monitors
that the welding current supplied by the welder is higher than the value set at this parameter;
if it is lower, an error message will be displayed (see the relevant paragraph).
This parameter may be activated by setting the CONTROL MODE in CUR. If the CONTROL
MODE parameter is set to NO (no control on the welding current), the parameter is not
displayed during the programming phase.
CURR. MAX
This parameter fixes a maximum current limit value. For each weld, the control unit monitors
that the welding current supplied by the welder is lower than the value set at this parameter; if
it is higher, an error message will be displayed (see the relevant paragraph).
This parameter may be activated by setting the CONTROL MODE in CUR. If the CONTROL
MODE parameter is set to NO (no control on the welding current), the parameter is not
displayed during the programming phase.
ANGLE MIN
This parameter fixes a minimum conduction angle limit value. For each weld, the control unit
monitors that the minimum welding current conduction angle supplied by the welder is higher
than the value set at this parameter; if it is lower, an error message will be displayed (see the
relevant paragraph).
This parameter may be activated by setting the CONTROL MODE in DEG. If the CONTROL
MODE parameter is set to NO (no control on the welding current), the parameter is not
displayed during the programming phase.
ANGLE MAX
This parameter fixes a maximum conduction angle limit value. For each weld, the control unit
monitors that the maximum welding current conduction angle supplied by the welder is lower
than the value set at this parameter; if it is higher, an error message will be displayed (see the
relevant paragraph).
This parameter may be activated by setting the CONTROL MODE in DEG. If the CONTROL
MODE parameter is set to NO (no control on the welding current), the parameter is not
displayed during the programming phase.
