6.7.2.58 F84: Pulse automatic adjustment
Sets the pulse mode that has the pulse automatic adjustment function. This function is available when set to the following
welding method.
In pulse welding, spatter generation will increase when the welding voltage is set at a low value and welding is carried
out in a way that short-circuit will occur moderately. Spatter generation during welding is suppressed in the pulse
automatic adjustment by automatically adjusting the pulse current waveform in a real time basis.
•
"0": Standard pulse mode
•
"1": Pulse mode for automatic adjustment
–
The adjustment amount of pulse automatic adjustment is updated occasionally during welding.
–
The adjustment amount of pulse automatic adjustment will be retained even after welding has
completed. If welding is started again, the pulse current waveform will start from the adjustment state
of the last welding completion, and automatic adjustment will be carried out from that state.
–
The retained adjustment amount can be checked in internal function F85 (Adjustment amount of pulse
automatic adjustment).
•
"2": Pulse mode for automatic adjustment / Fixing of adjustment value
–
Sets the adjustment amount of pulse automatic adjustment at a fixed value (currently retained value)
so that the adjustment amount will not be updated even if welding is carried out.
–
The adjustment amount of pulse automatic adjustment is set by carrying out the welding after setting
at "1" or by manually changing the setting of internal function F85 (Adjustment amount of pulse
automatic adjustment).
T I P S
When set at "1" or "2", the settings "ARC CONTROL" and "CONSTANT PENETRATION" will be
disabled.
Pulse automatic adjustment will not be carried out during welding at initial conditions and at
crater treatment.
Pulse automatic adjustment will be carried out when main welding is continuously performed
for 1 second or more. The function will not be carried out if the main welding is carried out for
less than 1 second.
Pulse automatic adjustment is a function specialized for welding by automatic machines.
Therefore, this function cannot be used when travel speed is "STANDARD".
