3.5 Pulse welding
The advantages of Pulse are a higher welding speed and deposition rate compared to short-arc welding, lower heat
input compared to spray-arc welding, a spatter-free globular arc and smooth appearance of the weld. Pulse is suitable
for all position welding. It is excellent for welding aluminum and stainless steel, especially when the material thickness is
small.
Pulse
Pulse is a synergic MIG/MAG welding process where the current is pulsed between the base current and the pulse cur-
rent.
>> To take Pulse welding process into use, go to "Control panel: Channels" on page39 and select an available
Pulse channel.
If there aren't any Pulse memory channels available, create a new one for Pulse process by selecting an available Pulse
welding program for the channel. Follow the instructions in "Control panel: Applying welding programs" on page53.
>> Once selected, the corresponding Pulse welding process parameters become available for adjustment in the
Welding parameters view. For more information, refer to the pulse welding parameters in "Control panel:
Welding parameters" on page44.
DPulse
DPulse is a double-pulse MIG/MAG welding process with two separate power levels. The welding power varies between
these two levels. The parameters of each level are controlled independently.
>> To take DPulse welding process into use, go to "Control panel: Channels" on page39 and select an available
Pulse channel.
If there aren't any Pulse memory channels available, create a new one for Pulse process by selecting an available Pulse
welding program for the channel. Follow the instructions in "Control panel: Applying welding programs" on page53.
>> Once selected, the corresponding DPulse welding process parameters become available for adjustment in the
Welding parameters view. For more information, refer to the pulse welding parameters in "Control panel:
Welding parameters" on page44.
3.5.1 MAX Cool process
MAX Cool is a synergic MIG/MAG welding process that is designed for root pass welds and sheet metal applications.
MAX Cool is suitable for all welding positions and provides a smooth arc, reducing spatter.
>> To take MAX Cool into use, go to the control panel's Welding parameters view and apply MAX Cool. Optionally,
go to the Memory channels view and create a new memory channel with MAX Cool process.
>> To adjust the wire feed speed while welding, or in the control panel's Home view, turn the left control knob.
The adjustment's effect on the plate thickness is also shown.
>> To fine tune the heat output while welding, or in the control panel's Home view, turn the right control knob.
Max Cool supports these filler wire and shielding gas combinations:
• Fe solid & Ar + 8…25 % CO

(1.0 mm, 1.2 mm)
• Fe solid & CO
2
(1.0 mm, 1.2 mm)
• Ss solid & Ar + 2 % CO
