Welding works are relevant at any time, and so far iron will be applied in the industry, the work of the welder will be more actual. But for a good result, it is enough to have only professional knowledge and skills. It is necessary to get a high-quality inverter for welding. How to choose a reliable and durable welding inverter for home or cottage?

Why do you need an inverter

It is often necessary to fight something at home or at the time of seasonal repair work at the cottage. Then the feet of the table moves, there the veranda glanced, here labor leaks ... It is difficult for the real owner without the skills of the welder and the corresponding equipment. Of course, you can use the services of the incoming master, but why pay several thousand rubles when you can do the same yourself and completely free? Hence the conclusion that the real owner should be not only home, but also economical.

Saving savings Returns, and you begin to understand this, as soon as you come across the choice of inverters for welding. To navigate, what are the indicators and what characteristics should a good inverter be posted?

Advantages of inverters

The main advantages of welding inverters include the elementality of the control. So, even an inexperienced welder can cope with household repair work without any problems. All welding machines have three functional modes that allow you to do everything quickly, simple and efficiently.

The most difficult thing in working with the inverter is toggave arc. Learning to do this correctly only practices and a lot of spoiled electrodes will help. But resourceful producers took care of this, significantly alleviate the life of novice welders with the "Hot Start" function. When the arc is lit, the increased current begins to be supplied in automatic mode, providing sustainable burning of the arc.

The "sticking" of the arc is the second largest nuisance of inexperienced welders. Yes, and experienced is also not in a special delight from such a phenomenon, but unlike amateurs, it can cope with the "sticking" without prejudice to work. So, in the process of working on conventional welding machines, a professional retains an electrode on the necessary distance from the welding tank to get high-quality and neat seam. One light touch to the metal surface will provoke a short circuit.

If the adhesive electrode does not tear off, then it will grow up and loses the coating. In this case, it will need to be replaced with a new one. Why do we paint so long what does not apply to inverters, but to conventional welding machines? Just only in order to emphasize another advantage of inverter cars. Thanks to the built-in microprocessor, the device in the blink of an eye reacts to the risk of short circuit. At this time, the special feature of Antistick stops the flow of current so that the welder can calmly tear the electrode from the metal surface.

Making conclusions from the foregoing, you can distinguish several advantages of welding inverters:

• simplicity in management;
• ideal for beginner and inexperienced welders;
• saves time, strength and money;
• compact;
• multifunctional.

Characteristics of inverters

So, when you realized that without a welding inverter, you did not make a white light, another problem appears - how to choose the best option? The most seductive advantage of such devices is their compact dimensions and a small weight. Such an inverter can easily take with you to leave or work on scaffolding. Also, the inverters are designed for cooking cast iron and stainless steel, which also cannot but rejoice. To determine the choice, think with what materials and with the elements of which thickness you plan to work to understand which diameter of the electrode you need. These are the fundamental moments from which the choice of characteristics will depend.

Duration of inclusion

The inclusion duration determines the level of installation of the installation, that is, the continuous operation of the inverter at a particular welding current power. The duration of switching on is measured as a percentage of the 10-thiminated working cycle. So, if this indicator is 60%, then at a temperature of 60s and 120a it will work for about 6 minutes. When the inverter turns off, it needs to be cooled and "stay" 4-5 minutes. "Why not do the duration of inclusion 100%?", - ask you. Everything is pretty prose - in any case, a break is needed to change the electrode, remove slags or perform any other manipulations and technical transitions. There is another subtlety - for each country it is characterized by its climate, respectively, for it their conditions for the duration of the inclusion of inverters are calculated. For Russia, for example, the ambient temperature is about 25 ° C, and for European countries - about 40s.

Power conditions

Power conditions - another important point when choosing welding equipment. When the inverter is connected directly to 220V, pay attention to the voltage indicators. If they are rather low, then the choice of the variant for which the range of permissible decrease in these values \u200b\u200bis specified so that it can function under reduced voltage. Such models like Reante Sai 220 Mon, Fubag 200 LV and EWM PICO 162 have such a characteristic. These are the best inverters that are able to work, even if the voltage in the network falls to 187V. But in any case, the voltage drop is reflected in the power and maximum current level.

Useful advice: If you need a welding inverter for a house with a current in 160a, then you should not hurry to buy a device with identical indicators. It is necessary to add about 30-35% of the reserve of power, so to speak, just in case. Suppose, now you need an inverter for cooking parts with a thickness of 10 mm, the length of operation is 60% and the diameter of the electrode is 4 mm, and in a year you will have to work with more serious elements. Will you not buy a new car every year?

Inverter manufacturers

The inverter is a serious and useful thing, and not only today - tomorrow, but in a year, five, ten. Such technique must be purchased from the future, with a margin, so it is extremely important before buying to familiarize yourself with manufacturers.

Today, all inverters for welding can be divided into two main technological types: MOSFET and IGBT. IGBT is more modern technology and is distinguished by high currents for the weight of the device. Speaking easier, they are light and powerful. MOSFET is an analog technology that does not differ in the same excellent characteristics as IGBT.

Inverters with inverters almost always goes a protective welding mask. This is a beautiful and pleasant gesture from the manufacturers, but we still recommend buying a separate professional mask, because the quality of such "gifts" is sometimes strongly depressing. But that would not damage the manufacturers of welding equipment, it is detailed instruction manual into the box with an inverter. Often they are limited to only with general information, believing that the buyer of such a serious a priori technique is an experienced welder and knows everything himself.
