It was previously believed that it was rather difficult to weld metal parts at home by welding. However, over time, the technique improved. Today, even a novice master can connect metal elements with a welding machine. To do this, you need to choose the right equipment in accordance with existing conditions and needs during operation. How to choose the best welding machine for the home will be discussed in detail below.
General characteristics of equipment
Which welding machine is suitable for home use? This question is of interest to many masters. To choose a suitable model, you need to familiarize yourself with the features and types of equipment presented.
Household welding machines on the market operate primarily from the network. They must take electricity and reduce its voltage. In this case, the current increases to the required level. Usually this indicator is 100-200 A. In some cases, the frequency of the current needs to be changed. Equipment is also used that can convert alternating current into direct current. The choice of the unit depends on the features of its operation.
In some cases, the arc is produced by devices that operate on battery or internal combustion engine. However, such equipment in everyday life is used much less frequently. Almost always, for home use, network welding machines are purchased. Each of them is an energy converter. There are several varieties of such equipment. Which welding machine is best for home, expert advice will help you figure it out. They claim that today the most popular are several types of devices:
- MMA - equipment for manual arc welding.
- MIG / MAG - semi-automatic units.
- TIG - devices for argon welding.
Choosing the best welding machine for home and garden, you need to consider several features. So that such equipment can be used in domestic conditions, you need to purchase only proven models from well-known manufacturers. The fact is that household power networks cannot provide high quality electricity. In them, often the voltage does not reach 220 V. Especially often, a similar situation is observed in the country, in a country house. Therefore, when choosing a welding machine, you need to find out the features of the electrical network. Based on these data, the apparatus is also selected. He must be able to work under similar conditions.
Welding technology is constantly being improved. Today it has become more mobile, compact and reliable. Manufacturers reduce the cost of equipment, develop branded service. Therefore, the demand for welding equipment is constantly growing.
Varieties
The best inverter welding machines for the home can be selected independently. You need to understand the differences between the main varieties of this technique. In accordance with the features of the device emit:
- inverters;
- transformers;
- rectifiers;
- semiautomatic devices.
What good welding machine is suitable for giving or at home? There are a number of differences between the listed units. Inverters are relatively new equipment. Electricity can change its characteristics several times using similar equipment. The current is rectified first. After that, it is smoothed when passing through a special filter. After that, the direct current is again converted into alternating current. Only its frequency will be higher than that of the input electricity.
After the inversion process, current flows through the mini-transformer. Here the current increases and the voltage decreases. After that, the energy passes through a high-pass filter and a rectifier. This complex process allows you to apply current to the electrode with a constant frequency. Inverters have many advantages. They are compact and reliable. The equipment can work without stopping for a long time.
At the same time, in the inverters you can adjust the current strength, which allows you to perform a variety of welding operations. The arc is well ignited and stabilized, since the process is controlled by a microprocessor. Inverters operate from a network in which significant voltage drops are detected. The result of the master’s work will be high, alloy splashing is minimized. It is a safe and functional equipment.
Transformers
Choosing the best welding machine for home and garden, you should pay attention to such a group as transformers. These units are relatively inexpensive. However, they did not receive much distribution in everyday life. The design of transformers for welding is simple, which makes the equipment maintainable. It is unpretentious in work and quite reliable.
However, many owners do not dare to purchase such equipment because of its large weight and dimensions. The quality of the seam is not high enough. It is difficult for beginners to cope with such an aggregate. It’s hard to hold the arc. Transformers consume a lot of energy and cannot be connected to a household network. Moreover, their efficiency is relatively small. This type of equipment is almost never purchased for home use.
Rectifiers and semiautomatic devices
Which welding machine is best for home? To answer this question, you need to consider all the types of household equipment on sale. Welding rectifiers are also on sale. The frequency of the current in such devices does not change. Energy passes through a rectifier system. Therefore, as a result, direct current is supplied to the electrode. The electric arc in this case becomes very stable. The design of the rectifier is much more complicated than that of a transformer. When rectifying electric current, it is necessary to constantly cool the equipment. For this, fans are provided in the design.
Many rectifier models have additional features. In them, the current can be filtered or coordinated. Also, measuring and protective equipment, as well as devices for starting adjustment, are often included in the kit. Manufacturers provide high stability of current and start-up of the device. For this, the design can include wind relays, thermostats, automatic machines, etc.
Choosing the best welding machine for the home, it should be noted that rectifiers have many advantages. They provide high quality seam. It is also easy to maintain the arc with this equipment. Even a beginner can use such equipment. The dimensions and weight of the rectifiers are less than those of transformers. The scope of the presented equipment is wide. Using a rectifier, you can weld cast iron, ferrous and non-ferrous metals and alloys.
The disadvantage of rectifiers is the high cost. It is comparable to inverters. In this case, during operation, you need to monitor the cooling system. Failures in her work are unacceptable. Using the device from a household network can be risky, since it is impossible to protect the system from power surges. The efficiency of rectifiers is less than that of inverters. Therefore, such a technique is acquired relatively infrequently.
Semiautomatic welding machines differ in features of work. The wire before being fed to the metal goes through a phase of melting in a gaseous medium. In the working area, it enters the weld pool. The seam in this case is protected from oxygen. The presented apparatus can weld even thin sheets of metal. The seam in this case turns out to be of high quality. Semi-automatic productivity is high. A wide range of applications is also a positive feature. Settings can be adjusted independently.
The disadvantage is the high cost of both the unit itself and the consumables. It is difficult to work with this equipment on the street.
How to choose equipment?
Choosing the best inverter welding machines or equipment of a different type for the home, you need to pay attention to a number of technical parameters. On sale are appliances powered by a single-phase and three-phase network. For domestic use, devices that can operate on 220 V or universal units 220/380 V are suitable. Also, most devices can operate on a network in which voltage surges are observed. It is necessary to pay attention to the extent to which the protection is triggered. Typically, the voltage range in household models is expanded by 12-16%. There are devices that are designed to work in a network with a low voltage (suitable for summer cottages) or high rates of electric current in the network.
When buying the best welding machine for an inverter-type house or other type of equipment, you need to pay attention to the idle speed. The ability to ignite the primary and secondary arc, maintaining its burning, depends on this. It is believed that the higher this indicator, the better. Modern inverters can maintain an arc even at an open circuit voltage of 30 V. But at the same time, many innovative devices are installed in the system.
The length of time for different models may vary significantly. If the equipment is European-made, the full cycle lasting 10 minutes is taken into account. For domestic technology, this figure is 5 minutes.
It must be understood that if the manufacturer indicated in the instructions a continuous operation time of 30%, then for a European unit, in fact, it is 3 minutes. At the same time, work will continue in 7 minutes. In practice, no one has cooked for so long. Electrodes need to be replaced more often, to clean off the slag from the seam or move to another place of work.
Operate equipment in accordance with protection class. At the same time, cooking in the rain is prohibited. The ambient temperature should be from -40 º to +40 º.
If you need to work in the field, you need to choose models that work from a generator. It is also worth determining before buying what materials the device is intended for. Equipment may have additional features. They are selected in accordance with the features of operation.
