Inverter welding machine. Which is better for the house?

The principle of operation of the welding apparatus - straightening and converting to alternating current with high frequency

Inverter equipment. The apparatus and characteristics

All of us are accustomed to at the mouth of a welding apparatus is a huge box, which has in its transformer device. It is this piece of equipment is responsible for the current production of a fairly large force, which leads him to work and support the welding arc. Apparatus inverter is able to reproduce the same process, but in this embodiment the current generated by the inverter.

Inverter equipment is arranged much more complicated than the outdated transformer model. It line current passes four phases conversion:

• rectification, smoothing special filter;
• conversion to alternating current with high frequency;
• voltage drop with a parallel increase in the current strength even to 250A;
• current rectification.

To do this, provided there is a network filter equipment, rectifiers and inverters. The resulting output, high current indicators are able to create a fairly powerful arc that is easy to melt almost any metal.

classification of inverters

Depending on the purpose, devices are used with different current rates at the output. Usually they are divided into:

• thin (140-160 A);
• moderately (160-200 A);
• high power (200-250 A).

The internal structure of the inverter welding machine

The first - the weakest, their use is to create a small cosmetic seams and works with a metal having a small thickness. medium power devices - quite common, it is easy to cope with large volumes and produce fairly high-quality connection. High power can be attributed to professional applications, they are applied, if required welding metal surfaces having a large thickness.

Power - quite an important indicator on which to focus attention in the selection of equipment such as an inverter welder. What is the best fit for home, decide, of course, the buyer, but it is worth to focus on other characteristics.

Useful advice! Work with the welding inverter is only necessary in a special mask. Powerful light rays can damage your eyes.

Types of welding inverter type

Another inverters are divided by type of welding conditions:

• Manual arc (MMA);
• Semiautomatic (MIG / MAG);
• TIG welding using argon (TIG);
• plasma cutting (CUT).

For the home environment is perfect for MMA equipment with marking. This kind of welding inverters is lightweight, but at the same time, almost perfect for making any household tasks. To him it will need to purchase the most common electrodes.

Inverters labeled MMA are ideal for use at home or at the cottage

Semi-automatic welding machines are mainly used on an industrial scale and will not fit for the home. Output and dimensions in such equipment is much higher. The principle of its work consists in supplying special wire to the arc, resulting in a weld.

Welding with TIG machine - a complex process. For special uses it tungsten electrodes, and arcing occurs by reaction with an inert gas. Such equipment is quite expensive and its use in the home simply impractical as well as, the use of units of the following type. Machines for plasma cutting, in fact, are not welders, although some work as well as an inverter welder. What better option is ideal for use at home, now more or less clear.

Additional features of the welding inverter and its advantages

For beginners in the weld actually be superfluous additional features to facilitate the work. Almost all inverters increase the current strength at the beginning of the operation, resulting in a powerful arc launcher. This so-called 'hot start'. Its presence makes it possible to start work immediately after turning on the unit.

Not bad, if such a welding machine provides the function "antizalipaniya". The equipment automatically lowers the operating current at the time when the electrode set. After its separation, all parameters are restored. Another handy feature - the crossing of the welding arc. It allows you to get high-quality arc with minimal spatter.

In some models of welding machines are provided and forcing functions antizalipaniya

Useful advice! Often it is impossible to create a good arc at the first experience with a welding machine. That it turned out, you need to strike sharply on the electrode surface of the metal, like a match.

In addition, the inverter greatly facilitates welding works, it can work with different electrodes. It copes with such materials as iron, stainless steel, nonferrous metals.

Inverter welding machine. What better technical parameters?

Choosing an inverter device, you need to pay attention to other, no less important parameters. Quite important indicator is the range of input voltage. The ideal would be set to said voltage of 170 to 250, or within a tolerance of about 15%. The work of this unit will not be affected by power failures.

Duty cycle is usually indicated as a percentage. If this parameter value is specified to 60%, it means that after 10 minutes of operation of the equipment, it would need rest about 4 minutes. If this parameter is exceeded, the built-in protection work and the device turns off.

No less important parameter - the diameter of the electrode. It is best to choose a model that works with the electrodes 4-5 mm. Their use allows you to create more high-quality welds at a voltage reduction.

Useful advice! By purchasing a welding inverter need to pay attention to a nearby service center. In the event of a breakdown specialists quickly to help cope with the problem.

Proven manufacturers and models

Well proven in the market of welding machines German company FUBAG. Among its models, you can select the unit of any capacity for work at home and for professional welders. An ideal choice for the home will FUBAG IN 163. Such devices are insensitive to voltage drops, allow you to create a smooth and beautiful weld spatter-free metal drops. They are equipped with an efficient ventilation system, have built-in surge protection. Very easy to use, equipped with features of "fast start", "antizalipanie" and "arc force".

The electronic circuit of inverter welding machine works

The Italian brand Telwin long ago gained a reputation for quality products. Work inverters produced by this company 220. Distinctive features Telwin units is considered light weight and compactness. Inverter TELWIN FORCE 165 has everything needed for a beginner, features, greatly simplifying the work. It is easy to cope with surges in the range of 15%. Such equipment consumes little power, has a reliable cooling system. To this any suitable types of electrodes.

Compact inverter welding machine MMA 201 firm Tesla Weld

Good welding inverters produces firm ProfHelper. A whole line of machines called the Prestige, enjoys quite a high demand. Inverter Prestige 181S - one of the most common models. He is compact, it is possible to carry on the shoulder, allowing you to work even in remote places. He was not afraid of voltage drops. A standard set of features: "hot start", "antizalipanie", "forced arc" allow even a novice in the weld actually create high-quality, reliable seams.

If you are planning a home or on a suburban site to carry out any work on the arrangement of metal designs yourself, as well as possible, by the way, is the purchase of equipment such as welding machine inverter. Which is better - to choose the buyer. After reading this article, you can not be afraid to make the wrong choice.
