I thought spray transfer had the highest current range, so that might mean short circuiting is the lowest. I need to double-check my notes!

I might be mixing things up, but I feel like pulsed droplet transfer could be the answer. It seems to have specific applications.

I practiced a similar question, and I believe globular transfer has a wider range than short circuiting. It’s tricky!

I think short circuiting transfer has the lowest range, but I'm not completely sure. I remember it being used for thinner materials.
