The correct way to use the general 315 electric welding machine and the large welding 315 welding ma

The fan doesn't ring, the ignition doesn't work, the digital display is not normal, what is the reason?

Power supply, power cord. Three-phase power supply 380V, single-phase 220V.

There is no phase loss phenomenon in single-phase electricity, the host does not work, the fan rotates normally, check whether the power supply voltage between the power supply switch and the host is normal, and whether the power supply connection is disconnected or virtually connected.

If the host has a power fuse, check whether the fuse is blown.

Whether the host power switch is damaged. Use the AC file of the multimeter to measure whether the air switching voltage of the host is 380V or 220V.

There is a lack of phase in the three-phase electricity, and the host only uses two live wires to control the power supply. It means that the host has one less phase of electricity. The lack of phase will cause the host to have no output or the output voltage is low, the current is small, and the host with phase loss protection cannot work or there is no response when booted.

Eliminate the normal power supply between the power cord and the main engine, and check the internal power switch components of the welding machine: such as AC contactors, gear switches, etc., will also cause phase loss.

The above phase loss is different according to the different models, and the fault phenomena are different

Note: ZX7 series power supply (whether the power grid distribution box is transmitted) three-phase (two-phase) 380V voltage, measuring whether the three live wires are normal often exist most of the users use the pen to measure, the electric pen can not measure the voltage value, must need a multimeter to measure U1, U2, U3 line about 380V, and the three-phase voltage is basically balanced. Shanghai GM ZX7 series is manufactured according to the national standard GB-15579, 1-2004, and the voltage of each phase of the three-phase power supply cannot be lower or higher than 10%.

When the voltage is low 350V, the welding machine does not arc or the arc current is small, and the welding is not formed. The internal components of the welding machine above 510V are burned out.

The cause of the failure caused by the lack of phase is that the ZX7 series does not ignite or the current is small; 2. Welding series non-fuse; The no-load voltage of the ZX5 series is insufficient; Argon arc welding has no high frequency and no ignition; Plasma is not cut through high pressure. - Senda Welding Repair Manual.

Hello, the correct way to use the big welding 315 welding machine is: the first step, first adjust the current knob to the minimum, adjust the voltage knob to the maximum, test welding, do not move the voltage knob at this time, gradually increase the current, stop until you can weld normally; The second step is to adjust the current knob to the maximum, and then adjust the voltage knob to the minimum, test welding, do not move the current knob, and gradually increase the voltage until it can be welded normally; I believe that after such debugging, you should already feel the effect of current and voltage. The third step is to adjust the current and voltage knob to the minimum, and gradually increase the voltage and current (you need to adjust it in the process) until you find a match that you think is the best weld molding, the softest sound, and your own brother and brother can control.

Hello, the above is the answer given, if my answer is helpful to you, please give me a thumbs up for my service, your praise is my biggest motivation to move forward, I wish you a happy life

The maximum diameter of the welding machine can be welded, and more than the above can not be welded.

2. The rated output of the welding machine depends on whether the welding machine meets the standard (the actual output current can reach 315 amperes, and there is no false standard) and the level of the welding fixed load rate.

3. The welding machine mainly uses the high-temperature arc generated by the positive and negative electrodes in the instantaneous short circuit to melt the solder and the welded material on the electrode to achieve the purpose of combining them. The structure of the welding machine is very simple, to put it bluntly, it is a high-power transformer, which turns 220 380V AC into a low-voltage, high-current power supply, which can be DC or AC.

4. In addition, in the process of using the welding machine, a certain magnetic field will be generated around the welding machine, and the arc will produce radiation to the surroundings when burning, and there are infrared, ultraviolet and other light species in the arc light, as well as harmful substances such as metal vapor and soot, so sufficient protective measures must be taken during operation.

The models of the welding machine "315b" and "315" may be different versions of the same welding machine or from different manufacturers, or they may be two different welding machines, and the specific differences need to refer to the specific product parameters and instructions. Generally speaking, the model number of the welder represents its rated electrical rate, while the letters and suffixes represent different versions or special features. It is recommended that when you purchase or use an electric welding machine, carefully read the product manual and safety precautions, and operate in accordance with the specifications to ensure safety and effectiveness.

The difference between 250 welding machine and 315 welding machine: different currents and different power consumption.

250 welding machine current 250A, 315 welding machine current 315A. Due to the difference in rated current, the 315 will appear to consume more power, while the 250 will consume less power.

The welding machine uses the high-temperature arc generated by the positive and negative electrodes when they are short-circuited instantaneously to melt the solder and the welded material on the electrode, so that the contact object is combined.

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. Using the principle of inductance, the 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 electrodes when they are short-circuited in an instantaneous short circuit is used to melt the solder on the electrode to make them atomically combined.

Precautions for welding:

1. According to the technical conditions of the work, a reasonable welding process should be selected, and overload use is not allowed, high-current welding is not allowed, and metal cutting operations are not allowed with electric welding machines.

2. In the load welding, the temperature rise of the welding machine should not exceed 60 degrees for grade A and 80 degrees for grade B, otherwise the welding should be carried out after the machine is cooled down.

3. The working occasion of the welding machine should be kept dry and well ventilated.

4. The state is not in the welding, and the current is not allowed to be adjusted.

5. It is forbidden to do welding operations under the running workpiece of the crane.

6. If welding is carried out in the area of the crane wire rope, pay attention not to make the ground wire of the welding machine accidentally touch the wire rope of the lifting, so as to avoid accidents caused by sparks.

7. When the construction must be in the wet area, the welder must stand on the insulated wooden board to work, and is not allowed to touch the wire of the welding machine, and is not allowed to use the arm to clamp the live sail and burn the welding tong. <>
