The 220V welding machine always trips, what is the reason why the welding machine trips as soon as i

I just bought a small welding machine like you, at home is always tripped, replaced by a large air switch is still the same, very annoyed, and then I thought of a good solution, installed a single row of small air switches on the side of the welding machine, before using the small switch on the welding machine turned off, and then turn on the small switch after plugging in the power plug of the welding machine, so that it will not trip again, there is a detailed picture I drew below, I hope to solve your problem.

The welder always trips. It is generally found in the power input section. Because the current passing through the transformer will not cause the air switch or leakage protector to act.

1.There may be an input transformer in the welder or you see if there is a grounding situation.

2.Complex automatic no-load or power-saving electric welding machines need to look at their control circuits.

3.It may be that the air opening current is too small or there is a short circuit in the welder.

If you jump every time, it is likely that the empty opening is too small, as you said, sometimes you can not jump if you connect it, this is a leakage, you focus on measuring whether the two wires are short-circuited, or whether the welding machine is grounded inside.

I guess the air switch in your house is too small, because the current is very large when the welding machine uses electricity, try to change a larger air switch, if the larger air switch is still jumping, then it may be that the welding machine is short-circuited.

From what you said, it is a small air opening, in fact, it is not small, there is a problem with the choice of air opening, choose a D-type, generally used C-type, his tripping current will not exceed 10 times, and the welding machine belongs to the equipment with a large starting current, so you can choose a D-type.

The welding machine generally bears a lot of current, so it depends on how large the maximum load limit current of your air switch is, generally 50-100A, so whether it is an air switch or a gate knife depends on the load limit current and the size of the fuse. I hope to relieve your worries soon.

If there is a leakage in the Kenneng machine, you can take it apart and check it. It is best to use a gate knife with a point, of course, the wire is thicker, and the resistance is small! Air protection switch number, but it depends on the quality. There should be three wires, and there is a ground wire in it, which is connected to the shell.

Is it not where the air opening current is too small or there is a short circuit in the welding machine.

If it trips when it is powered on, there should be a serious short circuit or leakage, check the external wiring, whether the internal components are short circuited, and whether there is grounding. It should be that the rated current of the switch is too small, and it is okay when spot welding, and the current of pull welding is large.

The welding machine is the intention of using the high-temperature arc that occurs when the positive and negative north and south poles are short-circuited in an instantaneous to melt the solder and the welded material on the electrode, so that the contact object is combined. Its structure is very simple, it is a high-power transformer.

The welding machine can generally be divided into two kinds according to the output power supply, one is AC power supply, one is direct current, the principle of inductance, the inductance will undergo a huge voltage change when it is turned on and off, and the high-voltage arc that occurs when the positive and negative north and south poles are short-circuited in an instant to melt the solder on the electrode, so that they can reach the intention of atomic bonding.

If the device is powered on, it will trip, which is a short circuit inside the device. (Please also observe whether it is a missed jump or an empty jump).

If the equipment shows normal after powering on, and trips during use, it is usually because the rated power of the air opening is too small, and the instantaneous power of the butt welding machine is so large that the overload protection is triggered. Changing to a high-power air opening should solve the problem (it is recommended to use Class D air opening, and Type C air opening is suitable for lighting electricity).

The main reasons for the tripping of the welding machine are as follows: The rated current of the welding machine switch is small; The screws of the power interface of the welding machine are loose; The inside of the welding machine is grounded; The resistance of the welding machine is abnormal; The welding machine is damp; The welding machine is leaking; There is a problem with the circuit board inside the welding machine; The load switch of the welding machine is damaged.

Overload; The flash welding machine needs a lot of current when welding, and the large one will even reach more than 1000A, if the circuit breaker itself has a low capacity, it will cause the overload of the circuit breaker, so as to trip protection.

instantaneous current overload; The flash welding machine is an inductive load and has a large capacity, and there will be a large starting current when it is started instantaneously, which will exceed the rating.

Creepage; The equipment itself is divided into primary voltage and secondary voltage, the general secondary voltage is the safety voltage, the primary voltage is relatively high, when converting.

Welding parameters are set incorrectly; When the equipment is welding, it is necessary to set reasonable welding parameters, and the wrong welding parameters (such as.

1.The air switch has a low load.

2.For inverter welders, it may be IGBT power tubes or large capacitance breakdown short circuits.

3.For transformer welders, it may be a short circuit in the windings or a breakdown of the rectifier tube.

The butt welding machine trips and trips leakage, overcurrent trips, switch damage trips, and leakage protection may also trip by mistake, and the fault is slowly discharged.

1. The load switch allows small current. 2. The load switch is damaged. 3. The internal short circuit of the welding machine and the current overload.

First, the power is large, the current is large, and the impact is large.

Second, leakage.

Third, the trip model is not selected correctly, and the quality is not.

The butt welding machine trips as soon as it is used, which is because the line you connected is not in good contact or. Other reasons.

But although the style of the three scholars is to improve the karma is yes.

Summary. The welding machine will trip after a while, and there are generally several reasons for the welding machine to trip: 1. It appears in the power input part, that is, the voltage does not match, and the 380V welding machine uses 220V to work.

The current passing through the transformer will not cause the switch or leakage protector to operate. 2. The grounding condition is not good, and the welding machine trips due to self-protection. 3. Tripping caused by leakage somewhere; 4. The internal components of the welding machine are damaged, and professionals need to take a look at the situation of the circuit board.

Yes? The welding machine will trip after a while, and there are generally several reasons why the welding machine is tripped: 1. It appears in the power input part of Oak Town, that is, the voltage does not match, and the 380V welding machine uses 220V to work.

The current passing through the transformer will not cause the switch or leakage protector to operate. 2. The grounding condition is not good, and the welding machine trips due to self-protection. 3. Somewhere the leakage is good to start tripping, this is like lead; 4. The internal components of the welding machine are damaged, and professionals need to take a look at the situation of the circuit board.

Leakage tripping. Pro, there are the following reasons for the tripping of the welder's leakage family collapse circuit breaker: 1. The main reason for the tripping of the welder is that the rated current of the welder switch is small.

2. The screws of the power interface of the welding machine are loose. 3. The resistance value of the welding machine is abnormal. 4. The welding machine of the spike friend is damp, and the welding machine leaks.

5. There is a problem with the circuit board in the welding hole rounding machine. 6. The load switch of the welding machine is damaged.

If it is an inverter welding machine, there are other short-circuit faults, capacitors, switch tubes, etc.

Short circuit, the user checks the line, and the repair is ready to use.

The welding machine is a special transformer, and the working principle of the ordinary welding machine is similar to that of the transformer, which is a step-down transformer. At both ends of the secondary coil are the welded workpiece and the electrode, which ignite the arc and weld the gap of the workpiece and the electrode in the high temperature of the arc.

In order to adapt to the welding requirements of different materials and plate thicknesses, the welding current can be adjusted from tens of amperes to hundreds of amperes, and the required current value can be adjusted arbitrarily according to the thickness of the workpiece and the size of the diameter of the welding rod used.

It should be that the rated current of the switch is too small, and it is okay when spot welding, and the current of pull welding is large. You can't have a 6000A switch. What is the concept of 6000a? The 6000A can be a medium-sized factory.

If the power is on, there should be a serious short circuit or leakage, check the external wiring, whether the internal components are short-circuited, and whether there is grounding.
