User manual
Pulse MMA
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 standard welding). This process allows greater control during vertical-up
welding.
The pulse frequency is adjusted by pressing and releasing the «F(Hz)» button and then activating the main incremental encoder. Frequency value
increases when the incremental encoder is operated clockwise and decreases when it is operated anti-clockwise. Once the setting is set, it is possible
to press and release again the «F(Hz)» button to re-link the main incremental encoder to the current setting or to wait 2 seconds.

Description & advice
The Hot Start is an overcurrent during priming to prevent the wire from sticking to the part to be
welded. It is set in Intensity and Time.
The welding current is adjusted according to the type of electrode chosen (refer to the electrode
packaging).
Pulsation frequency of the PULSE mode.
The incrementation step depends on the frequency range:
Pulse frequency
0.4 Hz - 3 Hz
3 Hz - 500 Hz
The Arc Force is an overcurrent delivered when the electrode or drop comes into contact with the
solder bath in order to avoid sticking.
for more than 3 seconds, then selecting the «SEt» display by operating the main

Recommendations
The anti-sticking feature is recommended to safely remove the electrode
in case it is stuck to the metal.
The duration of the HotStart can be adjusted to make the arcing easier
when using difficult electrodes.
