A welding machine is more than a transformer and a torch. Between the incoming supply and the welding circuit sits a switching device that starts and stops the weld current, and in most production machines that device is a contactor. This article looks at the contactor's role inside a welding machine, how it is wired and controlled, and why vacuum contactors have become the preferred type. Where the Contactor Sits in the Machine In an AC resistance welding machine, the contactor connects the supply to the primary winding of the welding transformer. Close the contactor and the transformer is energized; open it and the weld circuit goes dead. The welding controller times the weld precisely, but the contactor is the device that physically makes and breaks the pow...
Resistance welding is a brutal duty for any switching device. A spot welder makes and breaks its welding circuit hundreds of times an hour, every hour, and each operation interrupts a heavy inductive current. That is why vacuum contactors have become the standard choice for resistance welding machines: they switch reliably, wear slowly, and need almost no maintenance. This article explains what a vacuum contactor does in a resistance welding circuit and how to size one correctly. Why Resistance Welding Is Hard on Switching A resistance welding machine steps mains voltage down to a few volts and steps the current up to thousands of amps at the electrodes. The switching device sits on the primary side of the welding transformer, where it opens and closes the circuit...
2D laser cutting machines trim flat sheets. 3D laser cutting machines trim the parts after they are formed: stamped panels, extruded profiles, tubes and castings. It is the process behind trimmed automotive body parts, chassis rails and hydroformed components, and it removes the need for hard trimming dies. This article explains how 3D laser cutting works, what the machines look like, and where it pays. What 3D Laser Cutting Means In 3D laser cutting, the laser head moves along the surface of a three-dimensional part and follows a programmed path, keeping the beam at the correct angle to the material. The part sits on a fixture that locates it precisely, because the program assumes the part is exactly where the fixture put it. The cut can be a trim line, a hole, a...
