WebThe short circuiting mode is actually one wherein the short circuiting mode and globular mode are both occurring at random. As the voltage increases from 17 volts to 22 volts the arc short circuits less frequently, and the arc increases its globular transfer. Voltages above 25 usually indicate a true globular arc or spray arc mode. WebMar 20, 2024 · Metal cored wire with a spray transfer mode offers a very good profile, deeper penetration, and spatter-free welds. With Spray transfer, you can maximize the benefits of metal-cored wire by: 1) You can weld faster due to the higher melt-off rate, and. 2) Spray transfer produces little to no spatter, so it will minimize post-weld cleanup.
