This is the Mesh Welding Machine Supplier to share with you about the principle and use skills of the mesh welding machine

Principle of Mesh Welding Machine

The mesh welding machine uses the high temperature arc generated when the positive and negative poles are short-circuited instantaneously to melt the solder and the material to be welded on the electrode to achieve the purpose of combining them. The structure of the mesh welding machine is very simple. To put it bluntly, it is a high-power transformer that transforms 220V AC into a low-voltage, high-current power supply, which can be DC or AC.

Welding transformers have their own characteristics, that is, they have a sharp drop in voltage. After the electrode is ignited, the voltage drops. In the adjustment of the working voltage of the mesh welding machine, in addition to the primary 220/380 voltage conversion, the secondary coil also has a tapped conversion voltage, and at the same time it is adjusted with an iron core.

The Mesh Welding Machine is generally a high-power transformer, which is made using the principle of inductance. The inductance will produce huge voltage changes when it is switched on and off. It is melted by the high-voltage arc generated by the positive and negative poles in an instantaneous short circuit. Solder on the electrode. To achieve the purpose of combining them. A voltage is applied between the electrode and the workpiece, and the arc is ignited by scratching or contacting, and the energy of the arc is used to melt the electrode and heat the base material.

Tips for using mesh welding machine

The main function of the mesh welder is welding. However, many other uses of this machine have been explored in many years of design, manufacture and use. Some techniques are briefly described as follows:

(1) In the maintenance of electromechanical equipment, the screws of the old equipment often cannot be screwed. In this case, the mesh welder can help a lot.

The method is: adjust the current of the mesh welding machine to the maximum and the voltage to the minimum. Use the ground wire of the mesh welder to connect the shell, and use the welding pliers to pinch a carbon rod to the screw to be tightened. Turn on the power for a few minutes until the screw becomes hot and red, then stop and add some oil or other oil while it is hot. When the screw is cool, it will be off as soon as it is screwed.

(2) When special parts such as copper wires and copper bars are encountered in the maintenance of electrical appliances and the parts cannot be welded by open flame (gas welding), the low voltage of the mesh welder can be used, and the current is adjusted to be connected to the welding part through a carbon rod. It can be soldered with silver solder, phosphor copper, solder, etc., or the copper wire itself can be soldered.

(3) When the motor is repaired and replaced, the low voltage and high current of the mesh welder can be used to dry and drain the stator and rotor coils to replace the drying box.

Method: remove the motor end cover and take out the rotor, connect the motor stator coil taps, such as abc (head) and def (tail) together, turn on the secondary power supply of the mesh welder, and then adjust the current of the mesh welder The size controls the temperature of the stator coil of the motor, and the rotor can also be inserted into the stator coil to adjust the temperature of the coil. This method has fast heating, uniform humidity, and no choice of venues, which is a time-saving, energy-saving and labor-saving measure.
