CHAPTER 6
- STOP BAD SPOTS
The machine may be stopped when a consecutive series of welds fall out of the regulated
limits. The number of consecutive welds that cause the control unit to stop is adjusted through
parameter STOP BAD SPOTS in the
SETUP
MENU
(for the programming directions, see the
relevant paragraph).
SETUP MENU
>STOP BAD SPOT T1 01
STOP BAD SPOT T2 00
STOP BAD SPOT T3 00
This value may range from 0 to 15. On programming the value to 0, the function is disabled.
As such, on exceeding the preset limits, this does not stop the welder. There are four STOP
SPOTS parameters, one for each available welding tool, so as to be able to differentiate the
max number of admissible out of limits spots for each tool used.
It must be pointed out that in order to count the out of limits welds, they must be
consecutive, one after the other. This is applicable to each tool used.
In addition to activating the function in the
SETUP
MENU
, the operator must enable the
CONTROL MODE parameter relevant to the current limits in the
PROGRAM DATA
menu.
PROGRAM DATA T1
TOOLS N° 1
WORKING MODE IK
>CONTROL MODE CUR
These parameters allow the operator to keep the consistency of the welding current under
control to help achieve constant quality results.
The control unit enables to select two different control modes:
Welding current limits
This mode is activated by setting parameter CONTROL MODE to CUR.
Two new parameters will be displayed:
LIM I MIN lower current limit
LIM I MAX upper current limit
These two parameters enable to set the welding current limit-values.
PROGRAM DATA T1
TOOLS N° 1
WORKING MODE IK
>CONTROL MODE CUR
PROGRAM DATA T1
>PAUSE 00
LIM I MIN 010.0kA
LIM I MAX 015.0kA
When the programmed condition occurs, the control unit stops and an error message is
displayed. The displayed message refers to the error condition of the last run weld. In current
control mode (CONTROL MODE = CUR), if the current value of the last weld is lower or
higher than the values set in the foregoing parameters, one of the following messages is
displayed:
99/128
STOP BAD SPOT MAX T1
WELD CURRENT [201]
LIMIT LOW
STOP BAD SPOT MAX T1
WELD CURRENT [202]
LIMIT HIGH
