CHAPTER 8
- 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 causes the control unit to stop is regulated
through parameter STOP BAD SPOTS in the
SETUP MENU
(for the programming directions,
see the relevant paragraph).
SETUP MENU
>STOP BAD SPOTS 01
AMMETER CAP. 40 kA
LANGUAGE ITA
This value may vary from 0 to 15. When programmed to 0, the function is disabled and
therefore the welder does not stop under any circumstance on exceeding set limits.
It is important to point out that out-of-limits welds must be consecutive in order to
count them.
In addition to activating the function in the SETUP MENU, the user must enable the
CONTROL MODE parameter relative to the current limits in the PROGRAM DATA menu.
PROGRAM DATA
>CONTROL MODE CUR
SQUEEZE 1
25.0
SQUEEZE 10.0
These parameters allow the user to keep the consistency of the welding current under control
to help achieve constant quality results.
The control unit may work in one of the two following control modes:
Welding current limits
This mode is activated by setting parameter CONTROL MODE to CUR.
In this case two new parameters are displayed:
CURR MIN lower current limit
CURR MAX higher current limit
that permit setting welding current limit values.
PROGRAM DATA
>CONTROL MODE CUR
SQUEEZE 1 25.0
SQUEEZE 10.0
PROGRAM DATA
>OFF TIME 00.0
CURR. MIN 10.0kA
CURR. MAX 15.0kA
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:
ERR 0106
STOP LIMIT
LOW CURRENT
ERR 0107
