Conduction angle limits
This mode is activated by setting parameter CONTROL MODE to DEG.
In this case two new parameters are displayed:
ANGLE MIN conduction angle lower limit
ANGLE MAX conduction angle upper limit
that permit setting current conduction angle limit values.
PROGRAM DATA
>CONTROL MODE DEG
SQUEEZE 1 25.0
SQUEEZE 10.0
PROGRAM DATA
>OFF TIME 00.0
ANGLE MIN 120
ANGLE MAX 145
In conduction angle control mode (CONTROL MODE = DEG), if the current conduction angle
value of the last weld is less than or greater than the values set in the foregoing parameters,
one of the following messages is displayed:
ERR 0108
STOP LIMIT
LOW ANGLE
ERR 0109
STOP LIMIT
HIGH ANGLE
Limits of welding current and conduction angle
This mode is activated by setting the parameter CONTROL MODE to ALL.
In this way the following four new parameters will be displayed:
CURR. MIN Minimum current limit
CURR. MAX Maximum current limit
ANGLE MIN Minimum conduction angle limit
ANGLE MAX Maximum conduction angle limit
They enable setting both the welding current value limits and the conduction angle current
limits.
PROGRAM DATA
>CONTROL MODE ALL
SQUEEZE 1 25.0
SQUEEZE 10.0
PROGRAM DATA
>MIN CURR 10.0kA
MAX CURR 15.0kA
ANGLE MIN 120
Whenever one of the programmed conditions takes place, the control unit stops and an error
message is displayed. The message shown refers to the error condition of the last welding
process that has been performed.
