14 - POST-POWER
The value expressed in this parameter indicates the post-welding power.
15 - HOLD TIME
The parameter HOLD indicates the time elapsing between the end of the welding process and the
opening of the electrodes. It allows a quicker cooling of the welding spot and prevents that the spot is
moved before a proper cooling.
16-OFF TIME
The OFF parameter indicates a machine waiting time, namely that elapsing between one machine cycle
and the next one when the welder is working in automatic cycle. When this value is set to zero, the
machine will go on working in single cycle; if it is set to another value, the machine will work in the
automatic cycle. When the machine works in, single cycle, the control unit will carry out a single cycle
each time it receives a start cycle signal. When the machine 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).
17 - CURR MIN / ANGLE MIN (MINIMUM CURRENT LIMIT OR CONDUCTION ANGLE)
This parameter expresses different data according to the control mode selected on parameter BCONTROL MODE.
When the control is set to current control mode (CONTROL MODE=CUR), this parameter fixes a
minimum current value. For each weld, the TE450 monitors that the welding current is higher than the
limit set on this parameter; if it is lower, an error message will be displayed (see the relevant
paragraph).
When the control is set to degree control mode (CONTROL MODE=DEG), this parameter fixes a
minimum conduction angle value. For each weld, the TE450 monitors that the welding current
conduction angle is higher than the limit set on this parameter; if it is lower, an error message will be
displayed (see the relevant paragraph).
If the B-CONTROL MODE parameter is set to NO (no control on the welding current), the parameter is
not displayed during the programming phase.
18 - CURR MAX / ANGLE MAX (MAXIMUM CURRENT LIMIT OR CONDUCTION ANGLE)
This parameter expresses different data according to the control mode selected on parameter BCONTROL MODE.
When the control is set to current control mode (CONTROL MODE=CUR), this parameter fixes a
maximum current value. For each weld, the TE450 monitors that the welding current is lower than the
limit set on this parameter; if it is higher, an error message will be displayed (see the relevant
paragraph).
When the control is set to degree control mode (CONTROL MODE=DEG), this parameter fixes a
maximum conduction angle value. For each weld, the TE450 monitors that the welding current
conduction angle is lower than the limit set on this parameter; if it is higher, an error message will be
displayed (see the relevant angle).
If the B-CONTROL MODE parameter is set to NO (no control on the welding current), the parameter is
not displayed during the programming phase.
