10. OPERATION (continued)
The following welding conditions can be adjusted by using the F key [12] and the
parameter adjusting knob [6], but only the welding conditions with* next to the
function numbers can be preset to the welding condition numbers.
(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 when welding is completed. Anti-stick (burnback) time
is preset to proper 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", time decreases in the negative direction and
increases in the positive direction. The fine adjustment range is 0 to r50 and the
unit is 0.01 seconds.
Ex. 1) When the setting value of anti-stick (burnback) time is 25 seconds, add
0.25 second to the standard anti-stick (burnback) time.
Ex. 2) When the setting value of anti-stick (burnback) time is -10, subtract 0.1
second from the standard anti-stick (burnback) time.
(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 electrode wire from fusing to base metal at the end of
welding. Anti-stick (Burnback) voltage is preset to proper conditions according to
welding methods and wire diameters at shipment, but it can be finely adjusted by
activating F2. The standard anti-stick (burnback) voltage is preset to “0”. When
the voltage is set in the negative direction, it decreases. When the voltage is set
in the positive direction, it increases. The fine adjustment range is 0 V to ±9.9V.
(3) Fine Adjustment of Slow-down Speed: F3*
Slowdown speed means the speed to feed wire that is slower than the feed rate
at normal welding during the period from startup to arc start. The slowdown
speed is preset to proper conditions according to welding methods and wire
diameters at shipment, but it can be finely adjusted by activating F3. The
standard slow-down speed is preset to “0”. When the slowdown speed is set in
the negative direction, it decreases. When the slowdown speed is set in the
positive direction, it increases. The fine adjustment range is 0 m/min to r1.0
m/min. When poor arc start occurred, lower the slowdown 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 1.3ft[0.4 m]/min.
