Inductance display:
Arc force (arc stiffness) will be displayed
6
Voltage display:
In the static condition, the preset voltage is displayed and
the actual arc voltage is displayed during the welding operation. When the
torch trigger is pressed without contact to the workpiece, the no-load voltage
is displayed.

Right knob:
Click the knob to select between
⑤
and
⑥
above and then turn
the knob to set the corresponding parameter. The corresponding parameter
on the main body will be adjusted and displayed automatically.
Press and hold the knob for 3 seconds and the gas valve will open. Press
the knob again and the gas valve will close.
Note: The three parameters of current, wire-feed speed and material thickness
are linked. When one of the parameters are adjusted, the other two are
automatically adjusted to fit the combination.
The built-in highly intelligent technology is so sophisticated that a myriad internal
parameters are recalled from the database once any of the three parameters are
adjusted and a revised welding program is automatically set. This greatly simplifies
the welding operation since it only requires input of the basic parameters and the
optimum parameter combination will be introduced by the system.
