6.7.2.14 F16: Slowdown speed adjustment
Slow-down speed is the speed to slowly feed the wire from the time of the machine start to the time of
arc start.
The slowdown speed is automatically set to an appropriate speed depending on the welding method and
wire diameter; meanwhile, it can be adjusted through this function if manual setting is preferred.
The setting range is ±1.0 m/min, yet cannot be adjusted slower than 0.4 m/min. Based on "0," adjusting
it to the negative direction lowers the speed, and adjusting it to the positive direction accelerates the
speed.
When the starting performance is poor, decrease the slow-down speed to a negative value (which lowers
the wire feed speed).
When the starting performance is not poor, setting the slow-down speed to a positive value (which
accelerates the wire feed speed) can shorten the tact time.
6.7.2.15 F17/F18: Anti-stick time/voltage adjustment
Set the anti-stick time/voltage, which is the anti-stick processing time and voltage. Optimum setting of
the anti-stick time/voltage enables to obtain the following effects:
• At the welding completion, wire adhesion to the base material can be prevented.
• The shape of wire tip can be arranged to obtain a stable start of the next welding.
The time and voltage for anti-stick process are automatically set to appropriate conditions depending on
the welding method (wire type) and wire diameter; meanwhile, it can be adjusted through this function
if wire should cause adhesion at the end of welding or if burning is too intense.
• Adjust the anti-stick process time in the range of ±50 (unit: 0.01 seconds) through the internal function F17.
Based on "0," adjusting it to the negative direction shortens the time, and adjusting it to the positive
extends the time.
• Adjust the anti-stick process voltage in the range of ± 9.9 V through the internal function F18. Based on
"0," adjusting it to the negative values decreases the voltage, and adjusting it to the positive increases the
voltage.
6.7.2.16 F19: Switching alarm setting
When alarm occurs, the output of welding power source can be stopped.
Yet for some alarm codes, it is possible to continue welding even if the alarm level is detected, which may
sometimes cause the alarm display to be ignored. Using the alarm setting switch function ensures to stop
the output from the welding power source.
• [ON]: any alarm detection stops the output of welding power source.
• [OFF]: alarm detection does not stop the output of welding power source.
