About pulse welding
Arc width changes by change pulse waveform.
Note
Changing the pulse waveform significantly will
block the action of globular transfer in pulse
welding and cause generation of spatter.

07
PULSE PEAK CUR
It adjusts the pulse peak current.
08
PULSE PEAK VOL
It adjusts the pulse base current.
09
PULSE RISE CUR
It adjusts the pulse rise current.
Adjust to
+
side for steeper slope.
10
PULSE FALL CUR
It adjusts the pulse fall current.
Adjust to
+
side for steeper slope.
14
PULSE FREQ
It adjusts the pulse frequency.
(*)
17
PULSE WIDTH
It fine-tunes the pulse peak on time in pulse welding.
18
CRATER DC
It specifies whether to use pulse in crater fill operation in
pulse welding.
19
INIT PLS DC
It specifies whether to use pulse in initial welding operation
in pulse welding.
(*):
”Pulse frequency” is not adjustable if the material is set to “AL-HARD (hard aluminum)” or
“AL-SOFT (soft aluminum)”.
Adjust the pulse frequency in the following manner if needed. Do not change the pulse fre-
quency significantly, otherwise, it can cause spatter generation and wire burning.
•
To increase the frequency, reduce the pulse peak current or pulse base current.
•
To reduce the frequency, increase the pulse peak current or pulse base current.

Number of burnback pulse
Adjust the number of pulse at the weld end point.
If the wire stick occurs frequently, increase this value.

PRISE
It fine-tunes pulse rise time.
Adjust to
+
side for longer rise time.
71
PFALL
It fine-tunes pulse fall time.
Adjust to
+
side for longer fall time.

P COTRL BLOW
It specifies arc blow control level in pulse welding.
83
ENDPLS
It specifies whether to apply pulse (on) or not (off) at the
end of welding operation.
(*):
In “PULSE [ON]” settings, FTT level (see submenu “
02
” of “Detail group 1”) and burnback time (see
sumbenu “
03
” of “Detail group 1”) adjustment are not applicable. In such case, adjust “number of
burnback pulse” to avoid wire stick.
