Spray transfer uses a high-current, stable arc to create a continuous stream of tiny molten droplets that transfer across the arc into the weld pool. Because droplets are deposited rapidly and constantly, the deposition rate is high and the weld bead is smooth and uniform. This mode is ideal for flat joints and horizontal positions where gravity helps the droplets feed into the pool and where a stable, argon-rich shielding gas keeps the spray consistent. It requires clean surfaces and proper gas shielding to maintain small droplet size and arc stability; it’s less suitable for vertical or overhead positions where control over transfer becomes difficult and spatter can increase.
