This YESWELDER Flux Core Gasless Mig Wire is a great choice for anyone needing to weld mild steel. It’s a gasless wire, which makes it super convenient, especially when you’re working outside where the wind can be a problem. You get two spools, each weighing 2 pounds. One spool is .030 inches and the other is .035 inches. This dual-size option is really smart because it lets you use the best size for different jobs without buying two separate spools. The wire is designed to be easy to use, giving you smooth welds and clean results.
