Difference between inverter and non-inverter

Do you know the difference between inverter and non-inverter? If you are not familiar with this new system, more and more machines include it because it brings major benefits to industry. If you still do not know what inverter technology is or what its benefits are, keep reading.

What is the difference between inverter and non-inverter?

Surprisingly, inverter technology is gaining more and more ground and has even spread to home cooling systems. It has similar applications in the metalworking industry, since an inverter device makes it possible to regulate the compressor speed so that it runs at a constant speed. Constant speed translates into greater efficiency.

And what is the difference between inverter and non-inverter? With non-inverter technology, by contrast, the air compressor runs at maximum power and speed: all or nothing. A non-inverter unit runs up to the maximum of its output and, once the desired limit is reached, it stops.

Let us take portable heaters as an example, so that you can understand the difference between inverter and non-inverter. A basic, low-cost portable heater has a temperature and speed control. If you want to heat your home to the maximum, you must select the fastest speed and the highest temperature. When the room has heated up completely, the machine switches off. When the appliance notices that the temperature is starting to drop, it starts again at full power. This means lower efficiency and higher energy consumption.

By contrast, devices that include inverter technology always run at a steady speed and power. In the case of heaters and even air conditioners, the speed varies whenever the previously set temperature is being reached. As a result, the appliance is more efficient, which can mean energy savings and higher efficiency in operation.

Inverter or non-inverter welders?

In the machining industry, among many other machines, welders include inverter technology. Inverter welders are a modern, updated and digitalised version of the traditional welders we have always known. Both devices, inverter and non-inverter, work in a similar way. The purpose of a welder is to convert alternating current into direct current to create an arc.

And what is the difference between inverter and non-inverter welders? An inverter welder uses silicon-based technology; non-inverter units, for their part, use transformers and rectifiers made of copper and aluminium, which makes them heavier. Choosing one type of welder or the other depends on your machining needs, because although inverter technology is the most modern, it also has its drawbacks.

Benefits of inverter welders

One of the reasons why more and more people choose inverter welders is that they are smaller and more compact; this makes the equipment easier to transport. They also use smaller transformers, which makes the device lighter and easy to carry. The same is not true of non-inverter welders, which are larger and heavier and need more space to handle.

Inverter welders consume less energy and can even be connected to a traditional household power supply. In other words, if you need to take the welder anywhere, you only have to plug it into the power available on site, without the need for an industrial generator, which non-inverter welders do require.

In addition, inverter welders allow the operator to adjust the output power electronically. This is one of the most important differences between inverter and non-inverter, since welders that do include this technology are more precise than conventional units when it comes to selecting the power.

Drawbacks of inverter welders

Unfortunately, one of these welders is much more delicate than a traditional welder. This is because its components, being electronic and more advanced, are more fragile and delicate. They can suffer electronic faults and the cost per amp can be higher if the welder is not used properly.

Traditional welders, despite their size, are more robust and have a mechanism that is simpler and more stable. This makes the devices longer-lasting. And, of course, their price is lower than that of an inverter welder.

Features of inverter welders

Versatile

Inverter welding machines can adapt to any electrical variable, including household power. They use software that makes these machines very versatile. They are also so light that they are easier to use than conventional units.

Reliable

Traditional welders are very sturdy and reliable, since they have been in industry for many years and have only improved over time. Inverter welders, by contrast, are units that appeared in the 80s. However, manufacturers have managed to make the electronic systems suffer fewer and fewer faults, resulting in highly reliable equipment.

Arc

Conventional machines are ideal for welding steel, but for machine shops, where greater precision is required and different materials are worked, an inverter welder is best. The software it includes makes the electric arc more stable and delivers higher performance.
