NEWS
Inside every resistance welding machine, the contactor works harder than almost any other component. It makes and breaks the welding circuit for every spot, seam and projection weld, and its condition shows up directly in weld quality. This article covers the contactor's job, how to size it, how long it lasts, and when to replace it. The Contactor's Job in a Resistance Welding Machine A resistance welding machine passes current through the workpieces between two electrodes, heating the interface until the metal fuses. The current path starts at the supply, passes through the welding transformer, and reaches the electrodes. The contactor sits in that path, on the primary side of the transformer, and it has two jobs: connect the transformer when a weld is co...
Most resistance welding machines run on 380-415 V three-phase supply, and their contactors are rated accordingly. But some welding circuits step up, rectify, or store energy at higher voltages, and those machines need contactors with higher voltage ratings, better insulation, and stricter safety interlocks. This article explains when a high voltage contactor is required for resistance welding and what changes when you move up the voltage scale. What "High Voltage" Means in This Context In industrial practice, "high voltage" usually means above 1 kV, and most welding machines never see that. What the term means on a welding machine is a contactor rated for the upper end of low voltage, 690 V, or for medium voltage in the kilovolt range where cap...
Welding equipment in most factories runs on AC mains, and the contactor that switches its transformer primary is therefore an AC device. AC vacuum contactors combine AC coil control with vacuum arc interruption, and choosing one correctly means understanding utilization categories, coil behavior and thermal ratings. This article explains the ratings that matter and how to read them. AC Contactors in Welding Equipment An AC contactor is rated for alternating-current circuits, with poles that open and close all phases together. In welding equipment it sits on the primary side of the welding transformer, connecting the three-phase or single-phase supply to the transformer under the control of the welding controller. The contactor has to carry the transformer's co...
