Electric inverter welders are popular tools for welding because they offer many advantages over conventional welders. They are more efficient, portable, versatile and can adjust the output current according to the welding needs. However, like any other device, they can also encounter some problems that may affect their performance or even damage them. In this blog post, we will discuss some of the common electric inverter welder problems and how to fix them.
I. What is an Electric Inverter Welder?
An electric inverter welder is a type of welding machine that uses an electronic circuit to convert the input AC power into a high-frequency AC current, which is then transformed into a low-voltage DC current for welding. This process allows the welder to control the output current precisely and adjust it according to the type and thickness of the metal being welded. An electric inverter welder can also switch between different welding modes, such as TIG, MIG, MMA, or plasma cutting.
II. What are the Benefits of an Electric Inverter Welder?
An electric inverter welder has many benefits over a conventional welder, such as:
Higher efficiency: An electric inverter welder can reduce power loss by up to 40%, which means lower electricity bills and less heat generation.
Greater portability: An electric inverter welder is much lighter and smaller than a conventional welder, which makes it easier to transport and store.
More versatility: An electric inverter welder can handle different types of metals and welding methods with ease, as it can adjust the output current and switch between different modes.
Better quality: An electric inverter welder can produce a more stable and consistent arc, which results in smoother and stronger welds with less spatter and distortion.
III. What are the Common Electric Inverter Welder Problems?
Despite their advantages, electric inverter welders are not immune to problems. Some of the common issues that may occur are:
No output current: This means that the welder is not producing any current for welding, even though it is turned on and connected to the power source. This could be caused by several reasons, such as a blown fuse, a faulty switch, a damaged circuit board, or a loose connection.
Low output current: This means that the welder is producing a lower current than expected, which may result in poor weld quality or insufficient penetration. This could be caused by factors such as low input voltage, incorrect settings, worn electrodes, or dirty terminals.
Overheating: This means that the welder is getting too hot and may shut down automatically or trigger a protection mode. This could be caused by factors such as high ambient temperature, insufficient ventilation, excessive duty cycle, or short circuits.
Arc instability: This means that the welder is producing an erratic or unstable arc, which may result in spatter, porosity, or weak welds. This could be caused by factors such as incorrect polarity, improper gas flow, contaminated electrodes, or interference from other devices.
IV. How to Fix Electric Inverter Welder Problems?
If you encounter any of the above problems with your electric inverter welder, you should first check the following things before attempting any repairs:
Read the user manual carefully and follow the instructions for troubleshooting and maintenance.
Make sure that the power source is adequate and stable, and that the input voltage matches the welder’s specifications.
Make sure that the welder is properly grounded and connected to the workpiece and the electrode holder.
Make sure that the settings are correct for the type and thickness of the metal being welded.
Make sure that the electrodes are clean and in good condition, and that they match the welding mode and polarity.
Make sure that the gas flow is sufficient and consistent, and that there are no leaks or blockages in the hoses or regulators.
Make sure that the terminals are clean and tight, and that there are no loose wires or connections.
Make sure that the welder is well-ventilated and not exposed to direct sunlight or moisture.
If you have checked all these things and still have problems with your electric inverter welder, you may need to contact a professional technician or service center for further assistance. Do not attempt to open or repair the welder yourself unless you have the necessary skills and tools. Doing so may void your warranty or cause more damage to your welder.
V. Conclusion
Electric inverter welders are great tools for welding, but they can also encounter some problems that may affect their performance or even damage them. By knowing what these problems are and how to fix them, you can ensure that your electric inverter welder works well and lasts long.
