4. Welding conditions and application sphere of the globular transfer
Globular transfer welding conditions:
1. Low and moderate welding current;
2. Moderate and high arc voltage;
3. Shielding: CO2 or argon based mixtures.
MIG/MAG globular transfer application is restricted to welding in the flat position.
There might be heavy spatter when using CO2 shielding.
All that, including an irregular geometry of the resulting weld, limits use of the globular transfer mode for production applications.
