How much is a 300A welding machine that can generate electricity and weld TO300A

Daze Power TO300A, is a diesel power generation electric welding machine, the auxiliary power supply is 5KW, equivalent to a small generator with some lighting and other equipment, welding the following welding rods, a good helper for outdoor welding, called: power generation and welding dual-purpose machine, Daze Power Sun Kaili.

If a single welding machine is brought with a generator set, it needs to double the starting current, and the old iron above is not very powerful! The power generation welding machine is welded by inverter finishing, and the effect is obvious.

Fei Na effort, the whole generator and then buy a welding machine, just one connection, separate can still be used, I am so neat.

The above old iron is method one.

What Daze Zhang Jialiang wants to say is, is it not good to use one machine for two purposes? Just go and bring a unit!

This is Daze machine, the market is positioned at about 3-40,000, and if you get the goods from the manufacturer, you can ask Sun Wei of Daze Power.

Diesel welding machines are indeed a lot more convenient, and the welding machines of Beijing Electric King, Shanghai Kubogawa, Shanghai Daze Power, Miller, Lincoln, and Kumagai are not bad.

12kw, the AC welding machine should be rated at 380V, that is, the primary side voltage; If 400A is the working current, the welding machine usually works (arcing) at a voltage of about 22-30V, then the rated power of the welding machine: 30x400 = 12000 1000 = 12kw.

An AC welding machine is essentially a special type of step-down transformer. By turning 220V and 380V alternating current into low-voltage alternating current, the alternating current welding machine is an electric welding machine with an output power source of AC power supply. The welding transformer has its own characteristics, and the external characteristics are the characteristics of the voltage dropping sharply after the electrode is ignited.

If you want to use a 380v 400v welder outdoors or in scenarios where electricity is not available**, you need to choose a generator that is large enough to provide power. Specifically, the power of the welder and the rated power of the generator must match to ensure that the welder can operate normally.

Generally speaking, the power of an ordinary 380v 400v welding machine is between 1kw-10kw, you need to choose a generator with a slightly higher rated power than the power of the welding machine. The specific amount of power required for the generator can be calculated according to the rated power of the welding machine and the power factor of the crack.

When choosing a generator, you also need to consider the following factors:

1.Load: You need to consider what the load of the generator is to make sure it can withstand the operation of the welder.

2.Climate: The power rating of the generator may vary in different climatic conditions. In the case of high temperature and high humidity, it is necessary to choose a generator with higher power.

3.If you need to use the generator for a long time, you can choose a rated power generator that is slightly higher than the demand of the electric welding machine to ensure that the generator can work continuously and stably.

In short, you need to make sure that the power rating and power factor of the selected generator can meet the needs of the welding machine, and choose a high-quality generator to guarantee its stable operation. It is advisable to consult a professional or read the relevant technical literature before purchasing a generator to ensure that you choose the right generator.

The power of the welding machine is 12kw. The AC welding machine should be rated at 380V, that is, the primary side voltage; 400A should be the secondary current. If.

400A is the working current, and the welding machine usually works (arc insensitive) voltage of about 22-30V, so the rated power of the welding machine: 30x400 = 12000 1000 = 12KW.

Welding machines can generally be divided into two types according to the type of output power supply, one is AC power supply and the other is direct current. They use the principle of inductance, the amount of inductance will produce a huge voltage change when it is turned on and off, and the high-voltage arc generated by the positive and negative poles in the instantaneous short circuit is used to melt the solder on the electrode to make them achieve the purpose of atomic bonding.

u=380v should be the primary voltage, and i=400a should be the secondary current. If yes;

400A is the working current, usually the working (arcing) voltage is about 22-30V, 30*400=12000 1000=12KVA

12000 380= The AC welding machine should be rated at 380V with a rated power of 12kva.

Can't answer according to the conditions you give:

There is no direct computational relationship with 400a.

380V is the 380V of the input power, and 400A is the 400A of the output. There is a conversion in between, and 400A is the maximum current output in constant current mode.

2.If the output voltage at 400A can be known, it can also be calculated (p=u*i efficiency power factor).

Single-phase 380V output 400A welding machine, rated capacity: 16 18kVA for the new type, 20 22kVA for the old type; No-load capacity: 40VA with power-saving device, 300VA without power-saving device;

380*400=152000 (watts) = kilowatts).

If it works normally, it is kilowatts.

According to the calculation formula of electric power, 1kva is known to be pure as 1000 watts, so 300kva is equal to 300000 watts. If the power of each 20kw welding machine is 20000 watts, then it can be calculated that 300000 20000=15, that is, the power supply of 300kva can carry 15 sets of 20kw welding machines. Of course, the actual situation also needs to consider factors such as the stability of the power supply and the carrying capacity of the wire, which need to be adjusted according to the specific situation.

How many watts does an electric welder have.

And how much current.

Dear, hello, the power of a 380V DC 400 welding machine is 160kw, and the current is about 421A. The power of the electric welding machine is usually calculated by the amount of current, and the power calculation formula of the DC electric welding machine is: the power slow Qi Lu rate = voltage and current.

Here, assuming that the voltage of the welding machine is 380V and the current is 400A, the power is 160kW. At the same time, according to Ohm's law, the relationship between current and disturbance power is: current = power voltage, so the current is about 421A.

Hello dear, <>

A 380V DC 400 welder is in the power range of 200 to 400 watts. A commonly used 400 welding machine has a power of 300 watts and can be powered at 6 kva and 7v currents can be reached. When calculating power, the following formula can be used:

Voltage Current = Power, i.e. 380V 7V = 2660W. If more power is needed, you can also change the transformer that regulates 260V to boost the voltage to a higher voltage level, such as 600V or 1000V, to get more power by rolling it. Compared with ordinary welding machines, the 400 power DC welding machine has a more powerful welding capacity and can quickly complete the welding operations of the Shiqing Group.

In addition, when welding metal materials, the 400 welding machine can make the welding effect better and more effective due to the continuous current and constant temperature. Welded parts are more beautiful and of better quality, which can meet different industrial needs. I hope my answer is helpful to you, and I wish you good health and a happy mood!

Hello, I've been waiting for you for a long time, the power of a 380V DC 400 welding machine is 400A. This means that this welder can provide a maximum DC current of 400 amps for welding work. The power of an electric welder is usually described in amps (A) or watts (W).

In this example, the power of the welder is 400A x 380V = 152,000W or 152 kW, which is the maximum power that the welder is capable of providing. It should be noted that the power tung roll is an important parameter of the electric welding machine, but it is not the only determining factor. Other factors of the welding machine, such as the ability to regulate the current, the range of application of the electrode diameter, the welding process suitable for different types of metals, etc., are also very important.
