WELDING PROCESSES
• Standard
This welding mode is suitable for most applications. It can be used with all types of coated, rutile, basic and cellulosic electrodes and on all materials:
steel, stainless steel and cast iron.
• Pulsed
This welding mode is suitable for applications in the vertical up position (PF). Pulsing keeps the weld pool cold while promoting material transfer.
Without pulsing, vertical up welding requires a «Christmas tree» movement, i.e. a difficult, triangular movement. Thanks to MMA pulsed welding ,
this movement is no longer necessary; depending on the thickness of your workpiece, a straight up movement may suffice. However, if you wish to
enlarge the weld pool, a simple sideways movement, similar to flat welding, is adequate. In this instance, you can set the pulse current frequency on
the display screen. This method offers greater control of the vertical welding process.
• AC
This welding mode is used in very specific cases where the arc is not stable or straight, when it is subjected to magnetic blow-outs (magnetised parts
or nearby magnetic fields, etc.). The alternating current leaves the welding arc unaffected by its electrical environment. It is necessary to check that
your coated electrode can be used with an AC current.
CHOOSING COATED ELECTRODES
• Rutile electrode: very easy to use in all welding positions.
• Basic electrode: used in all positions, suitable for safety work due to its increased mechanical properties.
• Cellulosic electrode: very dynamic arc with a high melting speed, its capacity for use in all positions makes it especially suitable for working on
pipelines.

ADJUSTING THE WELDING CURRENT
The following settings correspond to the available current range depending on the type and diameter of the electrode. These ranges are quite wide as
they depend on the application as well as the welding position.

Hot Start is a feature that delivers an overcurrent upon ignition to prevent the electrode from sticking to the
workpiece. The voltage (% of welding current) and time (seconds) can both be set.
