Anonymous users2024-02-11The winding data of the welding machine is calculated according to the design requirements of the welding machine and the welding process parameters. The winding data of the welding machine includes the number of turns of the coil, the wire diameter, the winding method, etc.
First of all, the data of the winding of the welding machine needs to determine the number of turns of the coil according to the power and working voltage of the welding machine. Generally speaking, the more power the welder, the more turns the coil has. The number of turns can be calculated using the following formula:
n = (v × 10^8) / (4 × f × b × a)
Where, N represents the number of turns of the coil, V represents the working voltage of the welding machine, F represents the working frequency of the welding machine, B represents the magnetic induction intensity of the coil, and A represents the cross-sectional area of the coil.
Secondly, the data of the winding of the welding machine also needs to consider the selection of wire diameter. The selection of wire diameter needs to be determined according to the power and current density of the welding machine. Generally speaking, the greater the power of the welder, the thicker the wire diameter. The wire diameter can be calculated using the following formula:
d = √(p / (k × i))
where D represents the wire diameter, P represents the power of the welding machine, K represents the current density, and I represents the current.
Finally, the winding data of the welding machine also needs to determine the winding method. Common winding methods include single-layer winding and multi-layer winding. Single-layer winding is suitable for electric welding machines with less power, and multi-layer winding is suitable for electric welding machines with higher power.
The choice of winding method needs to be determined according to the power of the welding machine and the size of the coil.
To sum up, the data of the winding of the electric welding machine is calculated according to the design requirements of the electric welding machine and the welding process parameters. By reasonably selecting the number of turns, wire diameter and winding method of the coil, the efficiency and performance of the welding machine can be improved.

Anonymous users2024-02-06Use vernier calipers to measure the diameter d of the cross-section of the welding wire, and calculate the cross-sectional area of the copper wire according to the area formula of the circle = , and then you can know the conductivity of the welding wire.
The specifications and models of commonly used welding machine cables are 16 square meters, 25 square meters, 35 square meters, 50 square meters, 70 square meters, 95 square meters, 120 square meters, etc.
The structure of the welding machine cable is a single core, generally a number of copper wires to form a copper wire group, and a multiple group of copper wires to form the conductor part of the welding machine cable, so the YH cable body is thicker, and there are hundreds of copper wires. The surrounding area of the copper wires is insulated with a layer of heat-resistant polyester film. The insulation layer is generally pure natural rubber, and the copper wire is oxygen-free copper, so as to ensure the good conductivity of the wire core and the safety of the cable.

Power frequency refers to the working frequency between 50 and 60Hz....The working frequency of the intermediate frequency is 800 to 1000Hz....That is to say, the IF does more work than the IF frequency....The operating frequency is different, so....The power is naturally different....The welding machine is a riser, with low electric high voltage.
1. The welding current of the intermediate frequency welding machine is close to complete DC, because there is no obvious peak current, the nugget size is steadily expanded, there is almost no spatter, and the welding quality is stable and the thermal efficiency is stable. >>>More
Today's electric welding machines are basically electronic, and there are few AC welding machines. Therefore, it is best to mail the electronic welding machine back to the manufacturer for maintenance.

An electric welding machine is a special transformer. The difference is that the voltage drop is small when the transformer is connected to the load, and the voltage drop is large when the welding machine is connected to the load. This is mainly achieved by mediating the amount of inductance of the magnetic flux and the series inductor. Although the circuit is closed, it is precisely because. >>>More
