.030 flux core wire is better for thinner metals and provides smoother welds with less spatter, making it easier to control for beginners and lighter projects. .035 wire, on the other hand, is better suited for welding thicker materials, as it allows for higher deposition rates and deeper penetration. The best choice depends on the thickness of the metal you’re welding and your specific project needs.
