Spray arc MIG welding can look effortless when you see an experienced welder do it—smooth, hot, and almost fluid—but getting there takes more than luck. I’ve had plenty of moments where the arc sputtered, the bead balled up, and nothing behaved the way I expected until I finally understood how voltage, wire speed, and gas mix work together.
