The transfer type that occurs at lower current and voltage levels with smaller diameter welding wires is

Explanation:
Short-circuit transfer happens at the lowest arc energy in GMAW. With a small-diameter wire, you can maintain a stable arc at low current and voltage. The molten metal at the wire tip forms a tiny droplet that touches the weld pool, causing a brief short circuit; as the circuit opens, the arc re-ignites and the next droplet transfers. This rapid on/off action keeps heat input low, which is ideal for welding thin materials or joints with gaps. In short, the combination of low current/voltage and small wire diameter favors short-circuit transfer.
