400641-006 - Tweco DC Ammeter Single Scale Replacement Gauge

Keep Your Machine Running True

When you are under the hood, you need to know exactly what your machine is putting out. The Tweco 400641-006 DC Ammeter is the replacement gauge you need when your old meter gets smashed, stuck, or just stops reading. We know that in the shop, equipment takes a beating. Gauges get cracked, and needles get bent. But flying blind without an accurate amp reading can lead to cold laps, burn-through, and failed inspections. This genuine Tweco part brings your front panel back to life, giving you the confidence that your settings are exactly where they need to be.

There is something to be said for a classic analog needle. It lets you see the arc stability in a way that flickering digital numbers just can't match. If your wire feed is surging or your contact tip is dragging, you'll see the needle jump, giving you instant feedback to adjust your technique or check your consumables. This single-scale meter is easy to read at a glance, even through a scratched helmet lens or from a few feet away. It’s built tough to handle the vibration of a running power source and the dusty environment of a busy fab shop.

Don't settle for generic, one-size-fits-all meters that might not fit your panel or read correctly with your machine's shunt. This is the specific part designed for your equipment, ensuring a perfect fit and accurate calibration right out of the box. Swapping it out is usually a quick job—disconnect the power, open the panel, swap the leads, and bolt it in. Get your rig back to spec and stop guessing your amperage. With the Tweco 400641-006, you are back in control of your heat and your weld quality.
