Special features

The welding controller features the following specifics:
 No function: "Weld without command"
 The "Stop circuit open / no 24 V" fault is automatically reset.
 The DC link voltage is verified outside the sequence, the fault message is
automatically reset.
 The Control is prepared for the administration of 1024 weld programs.
 The time within the current has to exceed a minimum threshold is adjustable. If
this threshold is not exceeded on average, the sequence is stopped and an
error message occurs.
 With start tip dress request function
7.1.1

Special function "Electrode gun life""

Each electrode is assigned a gun life counter. With each spot welded, this counter
is incremented by the proper wear value. The monitoring parameters of the gun
life are input for each electrode by programming the additional values "gun wear
warning" and "maximum gun wear". When the gun wear reaches the "gun wear
warning" or "maximum gun wear" values, a suitable status message will be
output. If "maximum gun wear" = 0 has been programmed, the function is not
active and wear is not registered.
7.1.2

Cutter change

The timer has additional counters that count each tip dress performed on each
electrode. These counters may be reset through the BOS 6000 user interface. If a
counter exceeds a programmed prewarning value, the "Prewarning dresser
blade" output will be set. When the programmed maximum value is reached, the
"End of stepper dresser blade" output will be set. The function is switched off if
the value "0" is specified as maximum value.
7.1.3

Preparation for control system PSQ6000 XQR

The control has been prepared for an extension with the PSQ6000 XQR controller
system.
 Spot repetitions are not welded in UIR mode but in KSR or PHA mode (relates
to measurement, regulation, monitoring and stepping).
