The Fundamentals of Voltage and Wire Feed Speed The foundation of successful thin metal welding is understanding the direct relationship between voltage and wire feed speed. For thin materials, you need a relatively lower voltage setting, typically in the range of 15 to 18 volts, to maintain a stable arc that does not generate excessive penetration.

Unlike welding thicker stock, there is no room for error; the heat input must be precisely controlled to match the material thickness. Gas Coverage and Flow Rate Optimization Shielding gas plays a vital role in the quality of your weld on thin materials.
Hesitation is the enemy of thin metal welding; holding the torch in one place for more than a fraction of a second will almost certainly result in a hole. Conversely, if the voltage is too low, the wire will crowd the contact tip, causing a rough, sputtering arc that fails to melt the parent metal effectively.

Furthermore, flow rate is just as important as the mixture itself. Workpiece Preparation and Backing.
