Whether you are a welding professional or a simple DIY enthusiast and you are interested in electric or “voltaic arc” welding, then we will talk about the characteristics and advantages of inverter welders.
The most advanced technology has also reached electric welders. I mean inverter technology. But before getting into the matter, let’s take a look at its predecessors.
traditional welders
Traditional electric welders had a transformer, which converted the input electrical energy to a much lower voltage, which made it possible to operate.
However, the transformer did not solve the voltage fluctuations, which caused less precision in the welding points, sticking of the electrodes in the pieces to be welded, and high electrical consumption, among other inconveniences.
To solve all this, the transformer was replaced by a transformer/rectifier. This new component, in addition to transforming the voltage, rectified the energy, making it more stable. But this process was done analogically.
It is at this point that the idea of carrying out this same process but digitally, through a chip or integrated circuit, arose. This was the birth of the inverter welder.
Operation of Inverter Welders
Below I will try to summarize, as simply as possible, how inverter welders work.
Inverter welders work with a full wave rectifier, transforming the 50/60 Hz frequency of input alternating current, into direct or direct current.
Next, this energy is transformed into high-frequency alternating current that is between 20,000 and 50,000 Hz.
And finally, this current will be transformed into direct current with the necessary power to carry out the welding.
Advantages of Inverter Welders
There are many advantages of inverter technology applied to electric welders. Next we will give some brushstrokes.
Easy transport equipment
In contrast to traditional, heavy and bulky welders, inverters are very easy and comfortable to transport due to their small size and weight. Proof of this is that there are from about 3 Kg of weight.
Multipurpose teams
Inverter welders are trained to perform welding of different types. With a single piece of equipment, TIG, MIG/MAG and MMA welding can be carried out.
efficient consumption
Substantially reduces electricity consumption to the minimum necessary.
Precision
It performs very precise and aesthetically perfect welds without any problem.
efficient work
The work cycles it provides are more efficient. So it is possible to weld for a longer time in a precise way, without the need to wait.
start
The arc starts immediately, and the ignition of the electrode does not contemplate the sticking problems that traditional welders had.
Price
Prices are quite competitive, taking into account all the advantages they provide over previous equipment.
Even if we are looking for an inverter welder for DIY use, we will find very efficient equipment at a very good price, even being turboventilated and having an LCD screen.
