What Is An Inverter Welder? And What Is The Best Inverter Welder On The Market?

The inverter welder is a new style of welder that has a lot of advantages over conventional welders that most are accustomed too.

These welders such silicon technology that's sophisticated as compared to the aluminum and copper transformer that are found in the traditional welder. People have been slow to adapt to this new welder but it's not a reliable and it costs you less money when you us it and it's being widely adopted.

Advantages Of The Inverter:

One advantage that this new welder has is that it's compact and small. Since the welder is portable it's easy to carry around to job sites. The inverters use smaller transformers so they are compact, sleek, portable, and weight less.

This is much different from a regular welder that is very cumbersome and they don't fit into small spaces. The inverter welder can do more jobs in less space and save you more time when you do use the equipment.

An inverter welder consumes less power and it also operates on your regular household current. The lower power consumption of these units allows them to be plugged into normal wall sockets so they don't need any high voltage current to operate them properly. These welders can save you a great deal of money due to their lower consumption of power.

Since they are smaller and use less power you don't need any industrial generators with them or use high voltage power. When you use the welder you can do the job in less time and you won't have as many poor welds as you would with regular welders.

You can also fine tune these welders to do the job you need to do. There's power adjustment ranges with the welder so you can change it when you need more power.


While these welders have great advantages they also have a few disadvantages too. You can use the welder on regular currents because the welder has high-tech components. These means that the welder can be fragile as compared to other welders and it can breakdown frequently due to the fact that the components just wear out faster. This means that over time the welder can end up costing you extra money if you have to repair it often or buy new parts for it on a regular basis.

A regular welder is a simple construction and this ends up being more reliable over the long-term due to its simplicity in construction. The regular welders end up being cheaper long-term investments that don't break down as often. For this reason it tends to make the size and weight of these more cumbersome units less of a factor.

Inverter Welders are a Great Option:

While you do pay more for the features of an inverter welder the cost is well worth it. You get a welder that's very portable so you can take it almost anywhere and get your work done with it. These welders won't solve every problem and older welders won't break down as much but the inverter welder uses new technology and it's a solid option for all your welding needs.

Here Are Notable Chinese Made Inverter Welders:

Probably the best Chinese manufactureded inverter:

Ramsond Multifunction Digital Inverter Plasma Cutter, TIG, and Arc welder.


  • Fifty Amp Plasma Cutter (It's a digital inverter air plasma)
  • Two hundred Amp Direct Current TIG Welder
  • Two Hundred Amp ARC Welder (MMA)
  • Dual Voltage and Dual Frequency (110v 220v 50-60 Hz) AUTOMATIC
  • The Pressure Guage and Current Display Digigally

Huagong Arc-200

With the Huagong Inverter Welder you have a high frequency of 20KHz. This inverter technology gives a lightweight, small volume which allows a lot of energy saving. But perhaps the best thing about this model is that with all its perks the most favourable is that it saves a lot of money on running costs. With its PWM control, the technology is advanced and allows the circuitry a wide-ranged voltage input of =15%. This delivers a great constant output current. But along with this - a great perk in any welding shopping - is that it reduces splatter and fumes, it avoids mess and unwanted distractions when using your welder. With this comes an Adaptive Arc Force which improves the arc stability and stops electrocutes from sticking and adding to unwanted mess.

A minor thing but a very useful point is that it has a very easy arc start that bends weld with ease and effectively. It has a hot start feature that gives off an excellent arc start, especially for difficult electrodes which can usually cause a problem with in the process of making.

Although this inverted welder is not for those who are inexperienced it offers advantages that make its use simple. With its lightweight and small volume it allows you to move the welder into different positions to conduct the job with ease and speed. Along with this it has a great energy-saving technology in stored - MOSFET.

The most amazing thing about this model, however, is that is has various protections against damaged risks such as overload of voltage, overload of current, voltage shortage and overheating.

KENMAI Digital MMA-250

When buying an inverter welder it is important to know what it is going to be used for - for home use or business. The KENMAI Digital is a very versatile machine that has a very advanced MOG/IGBT technology installed. With its versatile nature is the ability to adjust the frequency to a high rate - reaching up to 60Hz.

The ease of work is another crucial factor when welding shopping and this model has a fan-cooled, automatic protection of over-voltage. It does not just protect against that but also the over-current and thermostat used. It also has a moveable welding cable which will come in handy when working and even doing small jobs around the house.

A brilliant feature of this model is its sound-proof appearance and less splash quality - when working at home these factors are a big part of any work and would be a great plus. Finally, the KENMAI Digital can suit all kinds of basic and acid electrodes.
