You should use .030" welding wire for thinner materials (up to about 1/8 inch) because it provides better control and less heat input, reducing burn-through. Use .035" wire for thicker materials, as it offers higher deposition rates and better penetration. Choose the size based on the thickness of your workpiece and the requirements of your welding project.
