In the actual procurement process of welding equipment, some users still have doubts about the use process and scope of the spot welding machine . Let's take a look at the precautions for manufacturers and individuals in the welding field when purchasing spot welders.

　　In the first case, if your factory's workpieces are ferrous metals, you generally choose an AC medium frequency spot welder. Because the AC intermediate frequency spot welding machine adopts AC discharge welding, it is especially suitable for materials with larger resistance.

　　The AC intermediate frequency spot welding machine can implement single-point, double-point continuous, automatic control, and manual control of the welded workpiece by using single pulse, multi-pulse signals, cycle, time, voltage, current, and program control methods. Therefore, this kind of spot welding machine is generally suitable for welding of tungsten, molybdenum, iron, nickel, stainless steel and other metal sheets, rods, wires, and the application range is still very wide.

　　In addition, the AC intermediate frequency spot welding machine has the following advantages: better comprehensive benefits and higher cost performance; wide range of welding conditions; small and lightweight welding circuit; it can be widely used for spot welding of dissimilar metals.

　　In the second case, if you need a spot welder for welding non-ferrous metals, it is generally recommended to use an energy storage medium frequency spot welder. Because this type of spot welding machine uses energy storage capacitor discharge welding, it has the characteristics of small impact on the power grid, concentrated welding current, fast release speed, strong penetrating power, and small heat-affected area. At the same time, this type of spot welder has the characteristics of small welding heat affected zone, saving energy, and more accurate and stable current output.
