3 MIG/MAG WELDING
Main menu ----> Process
The arc in MIG/MAG welding m elts a filler wire (the electrode) that is continuously
fed into the weld, with the molten zone being protected by a shielding gas.
Pulsing is used to affect the transfer of the droplets from the arc so that it is stable
and does not produce spray, even with low weld data.
The table on page 68 shows the wire diameters that can be selected for MIG/MAG
welding with DIP/SPRAY.
The table on page 69 shows the wire diameters that can be selected for MIG/MAG
welding with PULSE.
