How to judge the winding direction of the welding machine and the correct connection of the wire of

The judgment of the winding direction of the electric welding machine is mainly determined according to the working principle of the electric welding machine and the structure of the coil. These two aspects will be introduced in detail below.

First of all, the working principle of the electric welding machine is to generate a magnetic field in the conductor through an electric current, which in turn generates an electromagnetic induction force that causes the coil to rotate. According to the right-hand rule, when the current passes through the wire, point the four fingers of the right hand in the direction of the current, then the direction of the thumb is the direction of the magnetic field. According to this principle, the winding direction of the welding machine can be determined.

Secondly, the structure of the coil can also be used to judge the winding direction of the welding machine. Generally speaking, the coil of an electric welding machine is made up of windings and iron cores. The winding is made of wires, while the iron core is used to strengthen the magnetic field.

The specific steps are as follows:

1.First, observe the winding direction of the coil. In general, the direction in which the coil is wound is from the start end to the end end. This can be determined by looking at the markings at the start and end ends of the wire.

2.Second, observe the position of the core. The core is generally located in the middle of the coil and is used to strengthen the magnetic field. According to the position of the iron core, the winding direction of the welding machine can be determined.

3.Finally, combined with the winding direction of the coil and the position of the core, the winding direction of the welding machine can be determined. If the coil is wound in the direction from the start end to the end end, and the core is inside the coil, then the winding direction of the welder is clockwise.

If the winding direction of the coil is from the end to the start end, and the core is on the outside of the coil, then the winding direction of the welder is counterclockwise.

In summary, by observing the winding direction of the coil and the position of the iron core, it is possible to judge the winding direction of the electric welding machine. Of course, in order to ensure the accuracy of judgment, it is best to refer to the instruction manual of the welding machine or consult a professional.

Open the lid and take a look.

Preparation tools: 1 welding machine, 1 welding wire (welding wire).

The correct connection method of the wire of the welding machine is as follows:

1. The connection position of the welding wire (welding wire) is at the welding tong icon on the front of the welding machine, and the clamp icon on the other side indicates that it is used to connect the grounding wire.

2. Remove the shell of the welding tong, connect and fix the welding wire to the welding tong, and then reinstall the shell of the welding tong, and then connect the welding wire and the welding tong.

3. Connect the welding wire (welding wire) with the welding machine: remove the front side baffle to expose the terminal inside, and then connect the end of the wire that is the terminal to the terminal shown by the welding machine, and then tighten it with bolts. Reset the front bezel.

The precautions for the wiring of the electric welding machine are:

1. The working environment of the welding machine should be consistent with the provisions on the technical specification of the welding machine. If the temperature is too high or too low, the humidity is too high, the air pressure is too low, and when working in a special environment with corrosiveness or quality, a welding machine suitable for the performance of special environmental conditions should be used, or protective measures should be taken.

2. The welding machine must be placed smoothly in a well-ventilated and dry place, and it is not allowed to be close to the dangerous environment of high heat and flammable and explosive rolling.

3. The welding machine should be prevented from hitting the big brother or violent vibration (especially the arc welding rectifier), and the welding machine used outdoors must have protective measures against rain and snow.

5. The power control device should be installed in a place where it is convenient for people to operate near the welding machine, and there is a safe access hall around it. <>
