3.4 Additional guidance to functions and features
This section summarizes some of the MasterMig functions and features and how to use them.
3.4.1 1-MIG
1-MIG is a MIG/MAG welding process where the voltage is defined automatically when you adjust the wire feed speed.
The voltage is calculated based on the welding program in use. The process is suitable for all materials, shielding gases
and welding positions.
3.4.2 Pulse welding
Pulse welding is possible in MasterMig 355 only.
Pulse
Pulse is an automatic MIG/MAG welding process where the current is pulsed between the base current and the pulse cur-
rent. 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.
>> To take Pulse into use, press the welding process button and select Pulse.
>> The corresponding pulse welding parameters become available for adjustment. For more information, refer to
'Pulse welding parameters' in Control panel: Welding parameters.
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 into use, press the welding process button and select DPulse.
>> Adjust wire feed speed and fine tuning in the Main view.
>> Adjust double pulse frequency and pulse ratio in the Welding parameters view.
3.4.3 MAX Cool process
Available as an option in MasterMig 355.
MAX Cool is a short arc MIG/MAG welding process that is designed for root pass welds and sheet metal (thin sheet)
applications. It’s fully current-controlled welding process. MAX Cool does not require the use of a separate voltage sens-
ing cable.
MAX Cool is suitable for all welding positions and provides a smooth arc, reducing spatter.
>> To take MAX Cool into use, press the control panel's welding process button and select MAX Cool.
>> To adjust the wire feed speed, in the Main view, turn the left control knob. The adjustment's effect on the plate
thickness is also shown.
