What is the contradiction between efficiency and power factor of welding machine?

In conclusion, we should pay attention to the fact that when the welding machine is running, it will actually have a certain efficiency. At the same time, on the other hand, it will actually have a certain power existence. In terms of the efficiency and power factor of the welding machine, in fact, it is very high. To a large extent, there is a certain relationship.

Later, in fact, we should pay attention to the efficiency and power factor of the welding operator, which is actually very contradictory. As far as the same motor is concerned, we should pay attention to its own efficiency, which is actually very high, and precisely because of this, its power factor is actually very low. On the contrary, it is inefficient, but for its power factor, it will be relatively high, the power is very high, in fact, for the use of motor will be beneficial.

As far as the power factor of the welding operator is relatively low, it will directly reduce the transmission efficiency of the power grid. It is precisely because of this that the power factor of the welding operator is actually relatively low, and precisely because of this, the reactive power loss of the power grid is large.

That is to say, the lower the motor efficiency of the welding machine, the greater its loss. And, on the other hand, for its AC motor, its loss is resistive. In this way, the greater the loss of the welding machine, the larger the P in the power triangle. In fact, the smaller the power factor angle is, the larger the power factor is.

On the contrary, the higher the efficiency of the welding machine is, in fact, the smaller its loss is, the smaller its power triangle is, and the smaller its power factor angle is, in fact, the smaller its power factor is. In order to satisfy the power factor of the motor on the welding machine and the two indicators of its efficiency, in fact, it will directly neglect the other.
