CHOICE OF COATED ELECTRODES
• Rutile electrode: very easy to use in all positions.
• Basic electrode: usable in all positions, it is suitable for structural work thanks to increased mechanical properties.
• Cellulosic electrode: very dynamic arc with a high melting rate and usable in all positions making it especially suitable for pipe work.

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.

• 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.

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).

The welding current is adjusted according to the type of electrode chosen (refer to the

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.
Pulse Description & advice
The electrode type determines specific parameters according to
the type of electrode used in order to optimize its weldability.
Anti-sticking is recommended to safely remove the electrode if it is
stuck to the metal (the power is automatically cut off).
