An AC spot welder is a machine that securely welds workpieces together. The AC spot welding machine is composed of a step-down transformer, a current regulator and a cooling system, as well as accessories such as welding wires and handles. There is no need to use an electrode when welding, just use the two workpieces to be welded as the two electrodes of the circuit, and use the high temperature generated at the contact resistance to instantly melt the metal, thereby firmly welding the workpieces together. Advantages of AC spot welding machine: 1. Good economic benefits: three-phase input, high power factor and energy saving 2. Expanded range of welding conditions 3. Small and lightweight welding circuit 4. Can widely spot weld dissimilar metals (1) Pre-pressing stage - the electrode is lowered to the current-on stage to ensure that the electrode is pressed against the workpiece, so that there is proper pressure between the workpieces. (2) Welding time - the welding current passes through the workpiece and generates heat to form a nugget. (3) Maintenance time - cut off the welding current, and continue to maintain the electrode pressure until the nugget solidifies to sufficient strength. (4) Rest time - the electrode starts to lift until the electrode starts to descend again, and the next welding cycle begins.
