• MMA Pulse / SMAW Pulse
This MMA Pulse welding mode is suitable for applications in the vertical up position (PF). The pulse mode keeps the weld pool cold and eases the
transfer of matter. Without the pulse mode, vertical-up welding requires a difficult «Christmas tree» shape triangular movement. With the MMA Pulsed
mode, this movement is no longer required and a simple straight up movement is enough (depending on the thickness of the workpiece). If you wish
to widen your weld pool, a simple lateral movement is enough (similar to normal welding). In this case the pulse current frequency can be adjusted
on the display. This process allows greater control during vertical-up welding.

Arc Force
• MMA AC / SMAW AC
The MMA AC mode is recommended in some very specific cases when the arc is not stable or straight, which may happen around magnets (magne-
tised weldpiece, magnefic field in the vicinity).. The AC (alternative current) prevents electrical interference and keeps the stable under these circums-
tances. The pulse frequency is set to 50Hz. It is necessary to check that the electrode can be used with AC.

0 - 100 %
The Hot Start is an overcurrent during priming to prevent the electrode from sticking to the
part to be welded. It is adjustable in intensity (% of welding current) and time (seconds).
0 - 2 sec.
The welding current is adjusted according to the type of electrode chosen (refer to the
10 - 400 A
electrode packaging).
The Arc Force is an overcurrent delivered when the electrode or drop comes into contact
-10 > +10%
with the solder bath in order to avoid sticking.
