"Globular transfer" is the bad process behind the pigeon crap welds. The
blob forms at the torch, then flies across in one go. As it's too cold
when it hits, it doesn't fuse cleanly. This is usually caused by
inadequate wre feed for the voltage.

Any shop using C25 at a moderate current is below spray parameters. That
doesn't mean they're doing pigeon crap welds or getting no penetration. They
would be experiencing more spatter than in spray mode. There is a workable
range below spray that includes globular transfer and definitely does not
result in a cold weld.
