As soon as the welding machine is turned on, the voltage shows 800 volts, what is going on?

In this case, it should be a short circuit in the display panel, in this case, I suggest that you can replace the display panel.

Under the voltage, the welding machine switch is measured to be good or bad, I don't know what welding machine you have, the DC one is generally the potentiometer, and the wire wrap generally does not appear in this situation

As soon as the welding machine is turned on, the voltage shows 800V, what is going on? That's because after the last time you used it, it was fixed at 800v and you didn't twist the knob over. Didn't tune in to other movies.

The boot voltage of the welding machine is displayed at 800 volts, which is because the power is too high.

This situation should be the cause of the short circuit, and in this case, you must pay attention to it, it is likely that there is a short circuit.

There will be energy pulses on the boot voltage, and suddenly the value is very high, and it is necessary to detect the internal situation.

The boot voltage of the welding machine shows 800V, which may be too high, and it can be set directly.

It has coils in it, and there are coils to process, and it's like a capacitor anyway, a bunch of things, and then there's a short period of tooth fighting.

What is going on with the electric buttock sports technology is about to show 800 households? Then it may be that your welding machine can fully adjust those systems, or adjust them to 200 micro.

The number displayed by the second machine is the number buffered by the circuit board when it is just opened, which is not very accurate.

And then as soon as you turn it on, the voltage shows 800 volts, what's going on? You need to find a professional electrician to help you solve this problem.

Then your welding machine is 999 wet as soon as the current is turned on, which means that he is still in the reaction, and it is recommended that you still have to wait patiently for a while.

It may be because there is a problem with the driving circuit of your big tube, which causes some of his over-the-top or left protection that doesn't work.

If there is no discharge welding at all during welding, it is a problem with the main circuit or control loop, and if it can actually be welded, it is a problem with the display or monitoring loop.

Hello, this is because the welding machine itself is a power supply with a relatively large internal impedance, the no-load voltage is 60 70 volts, and the arc voltage is reduced to the arc voltage after the arc is initiated. It is a short-circuit current at the time of arc initiation, and this short-circuit current is determined by the impedance of the welding machine, so it is a large current. Hope it helps.

For example, if you turn on a switch and turn on a light, it is a current, and if you turn on a light, the current becomes the current of two lights, and that's it.

Radiator welding.

2. There are two types of DC welding machines: one is the rectifier element installed on the basis of the AC motor, and the other is the DC generator. DC welding machine mainly welds non-ferrous metals and pig iron. The AC welding machine is mainly used to weld steel plates.

3. Argon arc welding machine, carbon dioxide protection welding machine, high-frequency welding machine, flash butt welding machine. The argon arc welding machine and carbon dioxide gas shielded welding machine can mainly weld thin plates and non-ferrous gold layers below 2mm. The flash butt welding machine is mainly docked with copper and aluminum joints.

First of all, all the domestic welding machines ZX7 within 400 cannot reach it.

This is normal for welding rods to work for a long time and it is recommended for more than 400 module machines.

The wiring inside has false connections, and the components are not soldered and have poor contact. Disassemble it and try to repair it with an electric soldering iron.
