The welding expert system will preset the welding parameters according to the selected wire size
and material thickness. The user can manually fine adjust it as well.
To adjust the welding current, please use the left adjusting knob; and to adjust the welding voltage,
please use the right adjusting knob.
Press the central adjusting knob to enter more parameter setting for MIG, like Run-in WFS,
inductance, spot time, etc.
6.2 Options and settings
MIG Options
The inductance option permits adjusting the arc performance, this option can be
used to help with starting and the weld bead profile. A higher inductance setting
provides a softer arc and alower inductance setting provides a crisper arc.
The spot time option permits adjusting the duration of the welding arc. This is used
for tack welds or spot welds. The spot-time option is available in MIG and Flux
cored welding modes.
The run-in option permits adjusting the wire feed speed prior to the arc being
established. A lower run-in speed permits smooth arc starts. After the arc is
established the run-in value is inactive and the set wire feed speed is present. The
run-in option is available in MIG and Flux cored welding modes.
MMA Options
The arc force option permits the user to control the penetration profile. A high arc
force value creates a crisp arc while a low arc force value creates a soft arc. The arc
force option is available in MMA mode.
The hot start option permits adjusting the amperage during arc initialization. After
the arc is established the welding current will decrease to the output current set by
the user. The hot start option is available in MMA mode.
