10. OPERATION
(Continued)
(3) Long press DISPLAY CHANGE key [7] again to exit the internal function mode.
Note: In the function mode, no confirmation for changing the function is carried out when it
is changed. Upon change of the setting by using the parameter adjusting knob[5], the
change becomes valid. Therefore, before changing a function setting, make sure that
the correct function number is selected and that the proper setting value for the
function number is set.
10.2.1 Setting of Internal Function (continued)
The following functions can be set or adjusted.
(1) Fine adjustment of Anti-stick(burnback) time: F1
Anti-stick(burnback) time means the processing time to prevent electrode wire from fusing to
base metal after welding is completed. Anti-stick(burnback) time is set to the appropriate
conditions according to welding methods and wire diameters at shipment, but it can be finely
adjusted by activating F1. The standard anti-stick(burnback) time is preset to “0”, and is
adjusted in either the negative or positive direction. The fine adjustment range is 0 to
±
50
with a unit being 0.01 seconds.
Ex. 1) The setting value is 25: to increase the standard anti-stick(burnback) time by 0.25 sec.
Ex. 2) The setting value is -10: to decrease the standard anti-stick(burnback) time by 0.1 sec.
(2) Fine adjustment of anti-stick(burnback) Voltage : F2
Anti-stick(burnback) voltage means the voltage which is output when processing is carried out
to prevent wire from sticking to the base metal at the end of welding. Anti-stick(burnback)
voltage is preset to proper conditions according to welding method and wire diameter at
shipment, but it can be finely adjusted by setting F2. The standard anti-stick(burnback) voltage
is preset to “0”. When required set F2 in the negative direction to reduce anti-stick voltage, or
set F2 in the positive direction to raise the voltage. The fine adjustment range is 0V to ±9.9V.
(3) Fine Adjustment of Slow Down Speed: F3
Slow-down speed means the speed to feed wire that is slower than the feed rate at normal
welding during the period from triggered torch switch to arc start. The slow down speed is
preset to proper conditions according to welding methods and diameters at shipment, but it can
be finely adjusted by activating F3. The standard slowdown speed is preset to “0” When the
slowdown speed is set in the negative direction, it decrease. When set F3 in the positive
direction, it increase. The fine adjustment range is 0 m/min – ±1.0 m/min. When poor arc start
occurred, lower the slow-down speed. Even when arc start is good, the slow-down speed can
be increased to shorten tact time.
NOTE: The minimum slow-down speed is 0.4 m/min.
