Calculate the correct amperage by considering your steel’s thickness to guarantee a strong, consistent weld. Use the general rule of thumb: roughly 1 amp per 0.001 inch of mild steel thickness. This ensures sufficient heat input without burning through or producing weak welds.

Calculate amperage by steel thickness—about 1 amp per 0.001 inch—for strong, consistent welds.

Here’s a quick guide:

For 1/8-inch steel, set your machine around 120–125 amps.
For 1/4-inch steel, increase amperage to 180–200 amps.
For 3/8-inch steel, aim for 250–300 amps.
Steel thicker than 1/2 inch requires industrial-grade welders and multiple passes.

Matching amperage precisely protects your workpiece and maximizes weld penetration and strength. Adjust amperage according to thickness to maintain ideal arc stability and bead quality. It’s also important to reduce amperage by about 20–30% when welding in vertical or overhead positions to prevent burn-through and maintain control.

Why Power Supply Voltage Matters for Welding?

When it comes to welding, knowing about voltage options—like 120V and 240V—is really important. These choices can greatly impact how well your welder performs and whether it’s right for your specific projects.

Higher voltage supplies tend to provide more consistent amperage. This means you can tackle longer welds and work with thicker materials without worrying about overheating.
