How to fix an electronic welding machine when encountering some common errors

1. Electronic welding machine errors and how to fix electronic welding machine

In the process of using an electronic welding machine, it is inevitable that the machine will malfunction or not work, even for skilled welders. So what is the cause and how to overcome these common mistakes? The following article by RX Tradex will provide you with knowledge on how to  fix electronic welding machine repair when encountering basic technical problems

1.1. Flickering electronic welding machine power supply

The electronic soldering machine is not working stably can be caused by a problem with the cooling fan. So, check if the fan is working properly.

If the fan of the welding machine does not rotate, the machine may have an open power supply. First of all, you need to check the electrical joints to see if there are any openings, and then check the power supply of the machine and disconnect the power circuit if necessary.

1.2. The machine automatically shuts off or fails to weld

There are various reasons why the welding machine automatically shuts down, such as the power supply to the machine is flickering, the machine works for a long time continuously, causing the machine to heat up and overload

If the machine power is not enough to weld large welds, the machine may also automatically shut down due to a burnt out power block or a blown fuse. This is a safety feature to prevent risks such as electrical shorts, fires and explosions, and shorten the life of the machine. In this case, you need to disconnect the power for at least 5 minutes and then restart it

1.3. Weak welding machine

Weak welding machines are a common problem that makes it difficult for users. Here are some of the main causes of weak welding machines

• The welding current is not adjusted correctly: To fix this, turn the power boost steering wheel clockwise
• The power input wire is too small: Switch to another larger wire (1mm² copper wire with a load of about 5A)
• Poor power supply due to broken bolts: Tighten the bolts from the power supply to the machine tightly
• Power voltage below 20%: To rectify, turn the steering wheel to the maximum soldering current to compensate for the low power supply. If it is still not enough, you should choose to buy a machine with an auxiliary pile for low power cases
• Pulling the welder too far away from the electrical circuit breaker: This causes a drop in voltage on the line. When pulling the welding machine away from the circuit breaker by more than 15m, use a larger wire than specified to reduce voltage drops on the conductors.
• The potential of the power supply is sufficient but not weldable: This may be due to insufficient generator power to supply the welding machine. It is necessary to change the power supply to overcome this situation.

1.4. Electricity output is too strong

• Improper adjustment of electrical output: This is an electronic welding machine error that people often make, to fix it, turn the steering wheel to adjust counterclockwise
• The input potential is too large: Adjust the source voltage again or choose another source that is more suitable
• The power of the welding machine is too large: The smallest output current is still greater than the current to be welded (especially when welding thin iron). In this case, it is recommended to choose a welding machine with a lower capacity

1.5. Large buzzing welding machine

If the welder makes a louder buzz than usual, the main cause is usually the bolts in the case that have not been securely installed or have become loose due to shipping.

To fix this situation, first disconnect the power and retighten all the bolts in the case. If the machine is dropped or dropped during transportation, it should be taken to reputable electronic welding machine repair facilities

1.6. Touching the case with an electric shock

It may be due to the machine operating in a humid environment or being exposed to metal dust for a long time, the machine is prone to electricity leakage to the housing

Another reason why the case is electrocuted may be due to the wires being misconnected, loose, or exposed in the case. Please check the joint again and tighten the bolt to prevent the electrical shock to the housing

In some cases, the welder may become short-circuited inside the intestine, resulting in an electric shock in the casing. If you encounter this situation, take the machine to the service station so that the technician has a way to repair the electronic welding machine

1.7. Hot-burned electrical joints

Because the bolt contacts are not tightened. To fix this, use sandpaper to clean the blackened burn area and re-tighten the bolts. If the joints are severely damaged, it is recommended to contact the service station to replace the contacts

1.8. The machine in use is smoky and has a burning smell or even fiery

The phenomenon of the welding machine being used smoking, smelling burning or even flaming usually occurs when small objects or ferrites accidentally fall into the machine, causing an electrical short circuit or explosion. To avoid these unfortunate incidents, during use, it is necessary to pay attention to carefully preserving the welding machine and regularly cleaning the machine to prevent dirt or iron mites from sticking to the machine.

1.9. The machine has electricity leakage

The welding machine runs in an environment with a lot of metal dust or moisture, mold: To fix it, use a pneumatic machine to clean the metal dust, and then dry the hip drying machine

If the wiring is not technically correct, which may cause the housing to be touched or the internal electrical short, check the connections again and tighten the bolts to prevent touching the case

To properly store the welding machine, avoid placing it in dusty places, humid environments, or leaving it outdoors for long periods of time. It is recommended to store the machine in a dry, cool and clean place to ensure the life of the machine.

2. Epilogue

Above are common electronic welding machine error and how to fix them. Hopefully, these detailed instructions will help you understand more about how to use electronic welding machines as well as effectively solve problems encountered and use them safely. Don’t forget to carry out periodic maintenance and thorough inspections to ensure that the welding machine always works stably. If encountering a more complicated problem, contact electronic welding machine repair centers for timely assistance.
