What is a welding inverter?
Welding inverters are relatively recent inventions that have already established themselves as reliable assistants. Welders have already been able to appreciate all their advantages and disadvantages. Previously, we had to deal with simple welding machines. Their transportation was very difficult, given the weight of the units. Inventions of welding inverters for a long time moved aside and old transformers, and rectifiers. The whole secret lies in their principle of action.
Principle of operation of welding inverters
It all starts with an AC input that has a frequency of 50 Hz. Further, it undergoes certain changes with the help of special filters that are in the welding inverter. As a result of these processes, there is already a direct current at the output. Next, the inverter directly comes into play. Its task is to convert DC to transistors. In this case, there is a significant reduction in frequency, and the current remains consistently high. So the problem with the welding arc was solved by manipulating the frequency.
Pros of welding inverters
The main advantage of all welding inverters is, of course, their light weight. In addition, the use of DC electrodes has become possible. To a large extent this has become useful when working with non-ferrous metals. You can also notice a large current range that can be adjusted. This allowed to engage in argon-arc welding, a feature of which is the use of non-consumable electrodes.
In addition, many models have the opportunity to make a hot start. The principle of this function is to quickly supply the maximum current to the electrode. This avoids the cases when the wire sticks to the surface during welding.
Minuses of inverters for welding
The cost of these devices is very different from conventional transformers. In addition, the repair of welding inverters is a very costly exercise. Plus, they are very susceptible to dust. In this regard, inverters need periodic inspections. To do this, each time, open the lid and remove all dirt. There are also significant limitations on the temperature regime in which a welding inverter can be used. In many ways it depends on the details that are installed in it. Be that as it may, it is strongly advised not to include it at -15 degrees.
In addition, from the disadvantages of welding inverters can be identified relatively small welding cables. This fact creates certain difficulties during work, but is not critical.
