WELDING PROCESSES
• STANDARD WELDING
This standard MMA welding mode is suitable for most welding applications. It enables welding with all types of coated, rutile, basic and cellulosic
electrodes, as well as on all materials: steel, stainless steel and cast iron.
• PULSED WELDING
The pulsed MMA welding mode is suitable for upright (PF) applications. The pulsed setting keeps the weld pool cold while promoting material transfer.
Without pulsing, vertical upward welding requires a «Christmas tree» movement, i.e. a difficult triangular movement. Thanks to Pulsed MMA welding,
it is no longer necessary to perform this movement. Depending on the thickness of your workpiece, a straight upward movement should suffice.
However, if you want to enlarge your weld pool, a simple sideways movement similar to downheld welding is sufficient.. In this case, you can set the
frequency of your pulsed current on the display monitor. This method offers greater control of the vertical welding operation.
CHOOSING COATED ELECTRODES
• Rutile electrodes: very easy to use in any position.
• Basic electrodes: it can be used in all positions and is suitable for safety work due to its increased mechanical properties.
• Cellulosic electrodes: a very powerful arc with a high melting speed, its ability to be used in all positions makes it especially suitable for pipeline work.

ADJUSTING THE WELDING CURRENT
The following settings correspond to the applicable current range depending on the type and diameter of the electrode used. These ranges are quite
large as they depend on the usage and the welding position.

ADJUSTING THE ARC FORCE
It is advisable to set the Arc Force to the middle position (0) to start welding and then adjust it according to the results obtained and individual welding
preferences. Note: The adjustment range of the Arc Force is specific to the type of electrode chosen.
POWER
A method developed for welding with DMOS-regulated energy control. As well as displaying the energy of the weld bead after welding, this mode
allows the setting of the thermal coefficient according to the standard used: One for ASME standards and 0.6 (TIG) or 0.8 (MMA/MIG-MAG) for
European standards. The energy displayed is calculated taking into account this coefficient.

0.6 > 1.2 mm
A push-pull torch can be connected to the power source via the socket (I-9). This type of torch allows the use of AlSi wire even in Ø 0.8 mm. This
torch can be used in all MIG-MAG welding modes. The Push-Pull torch is detected by simply pulling the trigger.
When using a push-pull torch with potentiometer, the highest control range setting can be set using the interface.
The potentiometer can then range anywhere between 50% and 100% within this setting.
