<Terms description>
Run-in speed
It slows down the wire feed speed immediately
after turning on the torch switch in order to
obtain solid arc start.
Burnback time
It is a duration of time to keep supplying the
output voltage after turning off the torch
switch to stop welding operation. It is to burn
off the wire extruding from the end of the
torch due to motor inertia.
< Note >
Applicable only
to “
PULSE [OFF]
” setting.
Penetration adjustment
Fine tune the penetration
Wire feed fine adjustment
It fine-tunes the wire feed speed
without
changing current waveform at welding.

=Preset value+(Preset value x Adjustment value)
Wave control
It fine-tunes the current waveform at initial
short circuit portion of short circuit current.
Standard (0): Normal setting.
Adjust to “-” direction:
To obtain soft arc or
reduce spatter.
Adjust to “+” direction:
To obtain hard arc or
improve arc stability in high speed welding.
