The structure of an electric welding machine is very simple, in other words, it is a high-power transformer, but when choosing an electric welding machine, the first thing we consider is our own situation. So, what kind of welding machine is good? How to choose an electric welding machine? Below, the editor will list some tips for choosing welding machines for everyone!

1、 To confirm that the workpiece being welded is made of black metal, an AC welding machine is generally used. Because AC welding machines use AC discharge welding, they are particularly suitable for materials with high resistance values. At the same time, AC welding machines can use single pulse, multi pulse signals, frequency, time, voltage, current, and program control methods to implement single point, double point continuous, automatic control, and manual control welding on the welded parts. Suitable for welding sheets, rods, and wires of various metals such as tungsten, molybdenum, iron, nickel, stainless steel, etc.

2、 To determine whether the material of the welded workpiece is non-ferrous metal, energy storage welding machines are generally selected. Because energy storage welding machines use energy storage capacitors for discharge welding, they have the characteristics of low impact on the power grid, concentrated welding current, fast release speed, strong penetration, and small heat affected area. Widely suitable for welding and processing various types of metal sheets, rods, and wires such as silver contacts, copper, aluminum, stainless steel, etc

3、 AC brazing machine should be used to determine whether the material of the welded workpiece is phosphor copper, manganese copper or copper braided wire. AC welding machines belong to a small category of AC welding machines, so they also use AC discharge welding. They use a welding transformer with a temporary load rate and graphite (tungsten) electrodes to form a high resistance heating zone. At the same time, by using single pulse, multi pulse signals, frequency, time, voltage, current, and program control methods, single point, double point continuous, automatic control, and manual control welding are implemented on the welded parts.

4、 Regarding metal wire materials The butt welding of bar materials should use a butt welding machine, which is divided into two-stage butt welding machines and three-stage butt welding machines. The metal wire butt welding machine for metal halide lamps is also known as a hard material wire guide machine. The metal wire butt welding machine for energy-saving lamps, fluorescent lamps, ordinary incandescent lamps, etc. is also known as a soft material wire guide machine.

5、 For workpieces that require packaging and welding, a sealing machine is generally used. The sealing machine is manually loaded and unloaded, and the machine automatically completes a series of actions such as inspection, transposition, sealing, vacuuming, nitrogen filling, welding, and resetting of the welded workpiece. When there is an error in manual feeding, the machine will not perform welding to protect the welding mold from damage. The rotation of the turntable, the up and down movement of the cylinder and oil cylinder, vacuum pumping, nitrogen filling, and other actions can all be operated by toggle switches to facilitate observation and adjustment of each action. The oil circuit of the oil cylinder is controlled by an electromagnetic valve to control the gas-liquid conversion cylinder, effectively avoiding oil leakage caused by direct control of the oil circuit. The turntable is driven by a rotating cylinder. Avoiding oil contamination caused by the application of lubricating oil during mechanical transmission. By improving the welding mold, it can be applied to other situations that require sealed welding.

6、 For special alloy materials that require high-precision and high standard welding, intermediate frequency inverter welding machines can be selected, or some good welding controllers can be used to match the welding machine.
