What results from using high currents in globular transfer with CO2 shielding gas?

Using high currents in globular transfer with CO2 shielding gas typically leads to increased heat and spatter, rather than lower spatter generation. In globular transfer, the metal droplets formed during welding are larger and tend to produce more spatter due to the high energy of the arc combined with the characteristics of CO2 as a shielding gas. The increased heat can cause excessive molten metal to be transferred, which contributes to the spatter problem.

Conversely, the choice that states lower spatter generation does not align with the characteristics of the process, as higher currents can actually exacerbate spatter issues. In globular transfer, the arc is less stable compared to other transfer modes, and while using CO2 may have cost benefits, it also tends to lead to higher levels of spatter. Thus, while the performance of GMAW can improve under certain conditions with adequate technique and settings, the fundamentals of high current usage in this transfer mode do not support a reduction in spatter.
