The short circuit transfer mode is typically found in solid MIG or metal-cored wires when the ratio of Argon in the shielding gas is 75 to 85% Argon, and the welding voltage is low. In the globular transfer mode, the weld metal transfers across the arc in a gravity feed.

Short circuited mode in overhead welding:
Short circuited mode of metal transfer is the preferred mode in overhead welding for several reasons:
- Reduced spatter: Short circuited mode helps in reducing spatter during the welding process. This is crucial in overhead welding as excessive spatter can lead to poor weld quality and may even cause safety hazards.
- Better control: Short circuit mode allows for better control over the welding process, ensuring that the weld pool is properly formed and the weld bead is consistent. This is especially important in overhead welding where gravity can affect the weld puddle.
- Lower heat input: Short circuit mode typically results in lower heat input compared to other modes of metal transfer. This can help prevent overheating of the base metal and minimize distortion, which is important in overhead welding where controlling heat input is crucial.
- Improved arc stability: Short circuit mode offers improved arc stability, making it easier to maintain a stable arc throughout the welding process. This is essential in overhead welding to ensure proper fusion and penetration.
In conclusion, short circuited mode of metal transfer is preferred in overhead welding due to its ability to reduce spatter, provide better control, lower heat input, and improve arc stability, ultimately leading to high-quality welds in overhead positions.
