A good owner has everything. In the event of an emergency, it does not run through the neighbors with a request to borrow an adjustable key or drill. It happens - you need to brew something, cut. Having got a welding inverter, it will be easy.

Advantages

The welding machine inverter is the highest stage of the welding transformer, more perfect. The inverter combines two functions. He:

• serves as a power supply;
• speakers the welding current generator.

Inverters of welding current:

• performance at times more;
• seam quality;
• mass, and, consequently, the size compared to the predecessor, just miniature;
• the performance features are constant, that is, the inverter will show itself well and with voltage fluctuations in the network, and if there is interference;
• Efficiency is sensitive above - almost 90%;
• sprinkling during welding does not compare with those sparks that fly out from under the hands of a welder working with a welding transformer;
• the process goes smoothly;
• losses are minimized.

But the fact that the inverter does not tolerate dust and, if it is functioning in conditions of construction, it needs to be often cleaned, the plus you can not call. And also special storage conditions: when the transformer calmly winter in the garage, then the condensate can be harmful for the inverter. Therefore, before running, bring it to heat and let it go well.

When is the best household, and when only professional?

When solving a dilemma: which welding inverter, prefer: household or professional, look at the existing differences:

• if the choice stops on the household, then it can actively act in a row for 10-20 minutes, and then rest 1 hour.;
• option for professionals withstands more intensive exploitation - 8-hour working cycle;
• inverters used in industrial processes laid the possibility of three-shift work, breaks, of course, are needed, but not long.

For the quality of welding, do not worry - it will be high regardless of the selected option. Limit can only time. So, if you do not rush, you can not look at this option.

How to choose a welding inverter

So, we decided: you are extremely necessary for a welding inverter for home. To the question, come comprehensively:

What come from when buying?

• First, it is necessary to clearly understand the question for yourself: "What are your tasks to solve with it?;
• Secondly, what work is you coming? It is possible to master their welding inverter 190 A, and in other cases and 160 A will be enough with his head;
• Third, what a welding inverter will better cope with the works arising in your farm. It depends on which environment is going to work with it.

What options are the value when choosing a welding inverter?

Selecting the welding inverter, find out whether it is responsible by those requests that you present to it, namely:

1. Which thick material is capable of working. This is not a celebrating question, as it depends on it:
   • mark of electrodes and diameter;
   • welding current.
2. What diameter electrodes did you decide to use in advance? Are they suitable for the material or details that you will connect with welding?
3. Will it provide the desired welding current value. And if you have already been determined with the diameter of the electrodes, it is possible to perform a very approximate calculation of the working current of the welding, based on the fact that from 30 to 40 A is accounted for to the conditional electrode with a diameter of 1 mm;
4. The choice of the welding inverter depends on which network will have to work:
   • 220 V - stationary network;
   • from the generator 220 V;
   • 3 phase network 380 to stationary;
   • from Generator 380 V.
5. How intensively it is planned to use this tool and in which amount of work it is coming. The remaining characteristics of welding current inverters are selected for continuous welding and its operating current;
6. Welding machines Inverters are returned to the duration of inclusion - PV. They are arranged so that they are normal for them, when intensive work, in this case, welding is replaced by interruptions (pauses). This mode was called re-short-term.
7. To the inverter, the welding description is necessarily attached and the welding current is marked - nominal. This is a current, consuming which and observing PV, the inverter will not come overheating. For example: Cooking metal with a thickness of 0.4 cm at PV \u003d 60% and operating current 120 A. Based on the fact that a stock is required from 30 to 50%, we choose the inverter welding 160, and even 190a.
8. Electrical networks have their own characteristics. Suppose you have a stationary network of 220 V, checking through certain intervals, what it actually, you can establish that there is no stability, and more often the voltage decreases. Then take the inverter that will not let and stop at low voltage. This is a welding inverter 200.
9. In the overwhelming majority, welding inverters are equipped with thermal protection. It is designed to turn off the tool if PV is broken. If this happened, you need to either reduce the current or increase the pauses.
10. If you are welding parts with different sizes of the walls in thickness, then the electrodes must be changed. It will take to reconfigure the current, and its value can be seen on the display or ammeter, due to the fact that there is a digital index in the inverter.
11. When you perform welding in dangerous places: closed spaces, cluster of humidity, then an inverter is needed here, which is able to provide your safety, that is, having a device that reduces the stroke voltage to a safe value: from 9 to 15 V, when the electrode does not touch the weldable Surfaces. Such inverters have the protection of the IP21 class.

Device welding inverter

Operating principle

The inversion of the voltage (phase shift) is based, which provides a microprocessor scheme, which makes it possible to adjust the currents smoothly with minimal deviations even in conditions of sharply incident and growing voltage.

1. An alternating current of 50 Hz arrives on the inverter rectifier, which is transformed into a permanent;
2. The filter smoothes it further;
3. Converters again make the voltage variable, but the frequency of the current increases 1000 times: from 20 to 50 kilohertz;
4. On a downstream transformer, the voltage drops to 50-90 volts, and currents increase to values \u200b\u200bcapable of ensuring the welding process, that is, from 60 to 200 A.

Features of the welding inverter device

• The specificity and nursing in the welding inverter device is the lack of a power transformer;
• Inverter there is a pre-transform of high frequency currents, which can provide a very small transformer, weighing grams 250, while in the welding transformer in copper bulky coils is converted to the electromotive force. So: the transformer in the welding inverter 190 will weigh about 0.3 kg, and the power transformer in the welding machine is 20 kg.

If the question is: what to buy a welding inverter depends on the state of finance, then it should be aware that the welding machine inverter is proportional to the number of functions embedded in it, configuration, the degree of fame of the developer and the contractor.

Overview of welding inverters

There are a lot of types of welding inverters in the market which choose? Here will meet:

1. Manufacturers who have a name and those that have to hear for the first time;
2. Prices are high and surprisingly low.

How not to be confused and cannot be seduced to buy the most inexpensive?

What welding inverter is better?

MMA welding inverters are particularly popular and in demand. In MMA mode using the coated electrode, Hitachi devices operate. Hitachi welding inverters are small. Consider the inverter Welding Description Hitachi W200, made in Italy:
