Inverter

Welding is one of the important processes in the construction of strong metal structures. The metal bond is rigid and stable by proper welding. On the other hand, improper welding may damage construction materials and increase costs and waste. Therefore, it is very important to buy a reliable welding machine. However, with the wide variety of products on the market, you may get confused. We’ve rounded up the best features of a welding machine to make the process easier for you.

How is welding done and what is an inverter?

Arc welding technology uses a high-powered electric “arc” to melt a piece of metal attached to a welding machine and an electrode similarly attached to the welding machine. Electric current “jumps” and passes through the air between two conductors, causing an electric arc to occur. In this situation, both the metal workpiece and the electrode are exposed to high electric current through the welding machine. This electric arc heats the metal to a very high temperature, melts the electrode and the metal in contact, and forms a weld pool that allows the two metals to fuse.

Arc welding works on a similar concept to conventional and inverter welding machines. Inverter technology has improved the ability to provide a constant, stable and desirable amount of output current. Inverters also include a mechanism to change the power source from AC to DC, and the DC power changes the smooth welding output to form a stable arc.

What are the advantages of the inverter?

Some of the advantages of inverter welding machines compared to its conventional types are:

• Higher and more stable arc quality than conventional welding machines.
• Inverter welding produces higher quality welding results.
• Inverter technology increases productivity.
• Compared to conventional welders, inverter welders use less energy.
• Has a cooling fan.

Guide to buying a welding machine

Buying an inverter welding machine may seem like a simple task, but in reality, choosing the right inverter welding machine is an important task that requires a lot of consideration. In the following, we examine eight very important and key points for buying an inverter welding machine:

Input power:

The input power in watts shows how much power the inverter welding machine is fed from the power grid. For example, you may need to power your welding machine with standard 220V household power. When purchasing an inverter welding machine, check that its input power is compatible with your local power grid. Make sure that the device has voltage and frequency according to your local power grid. Finding the right welding machine also depends on the location of the welding operation. You may connect your machine to a 115V AC outlet or a 220-240V AC source when welding indoors. At this voltage, most basic welding equipment is operational. This device may operate as a single-phase or three-phase device.

Output power:

The output power of the inverter welding machine shows in Ampere how much welding current you can use. This feature is important depending on your welding needs. The output power of the inverter welding machine is important to you. Choose the right output power depending on your welding needs. Output power is usually expressed in amps for welding current.

Type of electrodes to be used:

Each inverter welding machine may be designed for use with a specific type of electrodes. For example, some devices can weld rutile, steel, graphite, etc. electrodes. Make sure you choose a device that is compatible with the electrodes you need. Check that the inverter welding machine is capable of using the type of electrodes you want. Some devices are only capable of welding with certain electrodes.

Duty cycle:

Duty cycle or duty cycle refers to the length of time a welding machine can work continuously without stopping. If you need to use the device continuously for a long time, consider a higher duty cycle. To successfully weld some materials, such as heavy structural steel and pipes thicker than half an inch, you need good welding equipment or a high-quality welding machine. The duty cycle indicates as a percentage how long the inverter welding machine can work continuously for a certain period of time (usually 10 minutes). For example, if a welding machine has a duty cycle of 60%, this means that you can use it to weld continuously for 6 minutes and then you have to stop it to cool down.

In contrast, thinner metals require more sensitive welding equipment that delivers just the right amount of heat to create a weld. In this regard, welding aluminum is almost identical to welding a relatively thinner metal.

Security:

Security is an important point in any type of electrical device. Be sure of an inverter welding machine with safety features such as automatic shutdown in case of short circuit or overheating. The inverter welding machine must have appropriate safety features. This includes automatic short-circuit shutdown, over-temperature protection, effective cooling systems and electrical safety. Make sure the device you buy meets valid safety standards.

Size and weight:

The size and weight of the inverter welding machine is also important, especially if you need to use it in confined or portable environments. Make sure the device is easy to transport. The size and weight of the inverter welding machine can be important when it comes to easy transportation and space constraints. Depending on your needs, choose a device with a small size and light weight that you can easily move.

Build quality:

Choosing an inverter welding machine with good build quality is important. This means using high-quality materials and appropriate technology to design and manufacture the device. Make sure the manufacturing company has a strong track record and good after-sales service. High-quality materials, advanced technology and reliable after-sales service are points to consider.

Price:

Price is also one of the decision-making factors. Also, note that don’t just consider the original price of a welding machine. Instead, compare the price with the features and overall quality of the device to make a better decision and not just based on the price. Make sure that the machine you choose meets all your welding needs and is of high quality. The cost of a welding machine depends on how much current it can produce. Thicker metals often require more current to be effectively welded. Therefore, it is recommended to pay attention to the thickness of the fixtures and base metals you have to deal with for a project.

Considering these points, you can decide to buy an inverter welding machine that will bring you the most benefits. Before buying, it is better to read more about different products and compare them. You can also read the product specification sheet and learn about its features. Consider these features and the features that have been mentioned and choose the right inverter welding machine to buy according to your needs and limitations.
