Low noise pulsed MIG or Soft Silence Pulsé (SSP)
Offered for Ø 1 and 1.2mm steel and stainless steel, these new pulsed synergies provide:

a considerable reduction in arc noise

a softer more energetic arc with a broader spread

a hotter molten pool and hence a well wetted bead
Note : low noise pulsed mig makes the welding environment more pleasant. It carries more energy into the molten pool and can be used
very easily flat; but it is less convenient for welding in position.
7.2. ADVANCED WELDING CYCLE
2 - Step cycle
Pressing the trigger activates wire feed and pre-gas and turns on the welding current.
Releasing the trigger causes the welding to stop.
The Hot Start cycle is validated by the
t H S

OFF
parameter in the general Cycle submenu of the SETUP. It enables starting the welding
with a current peak that facilitates striking.
The down-slope enables weld bead finish with a decreasing level of welding.
4 - Step cycle
Pulling the trigger the first time activates the pre-gas, followed by Hot Start. Releasing the trigger starts the welding.
If HOT START is not active, welding will start immediately after pre-gas. In such a case, releasing the trigger (2
nd step) will have no effect, and
the welding cycle will continue.
Pressing the trigger in the welding phase (3rd step) enables control of the duration of the down-slope and anti-crater functions, according to
the pre-programmed time delay.
If there is no down-slope, releasing the trigger will immediately switch into post-gas (as programmed in the Setup).
In 4-Step mode (4T), releasing the trigger stops the anti-crater function if slope-down is ENABLED.
If slope-down is DISABLED, releasing the trigger will stop the POST-GAS.
The HOT START and slope-down functions are not available in manual mode..
