COATED ELECTRODE WELDING (MMA/SMAW)
• MMA/SMAW Standard
This MMA Standard welding mode is suitable for most applications. It can weld all type of electrodes : rutile, basic, cellulosic... and on any material:
steel, stainless steel, cast iron.

Description & advice
Percentage of
Hot Start
0 - 100 %
The Hot Start generates an overcurrent during the arcing phase to prevent the electrode
from sticking. It is adjustable in intensity (% of welding current) and time (seconds).
Hot Start duration 0 - 2 secs.
Welding current 10 - Imax.
The welding current is adjusted according to the type of electrode chosen (refer to the
electrode packaging).
Arc Force -10 > +10%
The Arc Force is an overcurrent delivered when the electrode or a drop comes into contact
with the weld pool in order to avoid sticking.
• MMA/SMAW Pulse
This MMA Pulse welding mode is useful 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 however you
wish to widen your weld pool, a simple lateral movement is enough (normal welding movement). In this case the pulse current frequency can be
adjusted on the display. This process allows greater control during vertical-up welding.

• Setting the welding intensity
The following settings correspond to the usable current range depending on the type and diameter of the electrode. These ranges are quite large as
they depend on the application and the welding position.
