Inverter welding machine: which one is better to choose for home and garden

Metals used to create durable designs. To exclude hidden defects and ensure that it is necessary to perform the most perfect quality of connections corresponding assembly operations. Such a convenient way to implement the plans, because it can be used at any time, as needed. It is economical because it does not have to pay for professional services. It is only necessary to choose the right welding machine inverter - which is better for the home and garden, you will learn after studying the materials of the article.

How to choose the right equipment without errors

To formulate the requirements for the equipment, you must first evaluate the performance of the proposed works. Many details are important:

• complexity of operations;
• thickness parts;
• seam length;
• environmental conditions;
• the duration of technological processes;
• parameters of the electrical power supply.

Should consult more with the possibilities of different models. Comprehensive analysis of all important factors to find out which is best for home and garden inverter welding machine.

Why this technique

If a severe blow with the tip cut off decorative column fences - contact a workshop. A good specialist in a few minutes will connect parts, remove the seam irregularities. Will only apply protective and decorative coatings. These operations can be performed independently.

But this example is simple only in theory. In fact, the metal posts can be set in concrete foundation. Dismantling of the connection is not possible without destroying the integrity of the product. Cause too expensive for a single work by a qualified artist. If you have a hardware defect will be remedied quickly, inexpensively. If the house has a compact welding inverter, it is useful for different tasks.

How it works, the device

To join metal parts using local temperature increase using an electric arc. To create the category with the necessary parameters used strong current.

For comparison it can be noted that a similar construction for 180-200 A, weighs more than 20 kg. "Stuffing" the same machine inverter (without housing, frame and mounting parts) - no more than one kilogram.

The desired result is obtained after the following chain of conversions:

• In an original source, the standard power supply network 220 V. Option 380 V (3-phase) is used in a professional-grade equipment, where high current output.
• After the "cut-off" of the lower half-waves and filtering creates a constant voltage. It is converted into square waves (meander) using the power semiconductor switches. At this stage, the frequency is increased from the original 60 Hz to 45-55 kHz.
• Next, the voltage is lowered to a level of from 30 V to 75 V. Accordingly, the current increases. Values ​​obtained from 30 A to 280 A is sufficient for playback welding technology.

With this shot, you can explore the features of a typical welding machine:

• Soft belt (1) is used to carry and hold technique on shoulder when performing working operations in confined spaces. The total weight of this compact models is about 4.5 kg. Therefore, this convenient device will not be superfluous. Rubber feet provide good stability for installing equipment on a flat surface.
• In a large digital display (2) displays the current output power. The following two buttons are set to control this parameter. Please note that all control elements are covered with a flexible protective layer. This solution prevents the penetration of moisture contamination. It extends the life of equipment.
• Button (3) selecting a desired mode (MMA / TIG).
• Lamp (4) lights up when the machine overheats. In this situation, the security lock, breaking the power is activated.
• Inverter turn on / off button (5).
• By jacks (6) is connected cables.
• The metal case made for ventilation slots (7). The openings are covered by lids directed downward. This does not interfere with the free movement of air, but prevents ingress of dust.

If you wish, the inverter can be made with your own hands. unit circuit is shown in this figure, which is able to provide the output current of 200 A. This is - modern technology, with the regulations, an indication of overheating and protection from surge voltage.

Inverter welding machine: which one is better for the home and garden with a view of functionality

To get a high-quality welded joint need to melt the parts in a limited area, without disturbing the underlying structures. To prevent contamination of the air in the working area create a protective environment. It also does not transmit oxygen, which activates the oxidation reaction.

Here it is depicted MMA technology. It is used for relatively small in scope. For large parts using the compound electrode with a larger diameter.

This technique (TIG) allows you to perform more complex actions with high quality. Here, in the heating region necessary size protective atmosphere is created by using an inert gas. The arc formed by the electrode is resistant to high temperatures, made of tungsten. To form a durable joint with the desired characteristics, in the melt zone is fed filler material.

In these technologies into the working zone through the central part of the burner is fed wire. It performs the function of the electrode and the filler material at a time. This solution complicates the design. But it is possible to create long continuous seams of high quality. Using the wire type shift and select appropriate modes combined products of different metals.

The group of semi-automatic methods is divided into two categories:

• MIG - applying inert gas to create a protective environment.
• MAG - the use of carbon dioxide. In this embodiment, consumables cheaper but somewhat worse quality compound.

Important! If you choose what is best to buy a welding inverter, specialized forums and other information sources should be used for additional information. The main thing - to decide with the purpose equipment.

Welding machines Inverters: how to choose the price and technical parameters of the best model

to connect steel partsRelatively small amounts of working operations is enough to buy the device class MMA. It weighs a bit, suitable for immediate operation without gas cylinders.

The cost of semi-professional inverter welding machine (MIG / MAG) above. But it is - a universal technique. With it you can create high-quality seams even with billet aluminum. This metal goes into a liquid state at a temperature of + 660 ° C. A film of oxide compounds is formed on the surface thereof, melts at + 2000 ° C and above. The following parameters are required here:

• small distance to the connection point;
• strong current and accurate setting of its value;
• the absence of impurities in the melt zone.

To satisfy these conditions apply apparatus MIG / MAG, the inert gas is argon, large diameter wire.

To find out what is best for home and garden welding machine inverter, experts recommend pay attention to the following characteristics:

• Welding type (MMA, TIG, and MIG / MAG).
• Input voltage. If large permissible deviation from the nominal value of 220 V, stable technique will work when connected to different networks.
• Maximum power is checked to ensure compatibility with the power supply parameters (stationary type, or a generator).
• output current value determines potential. For the majority of household tasks will be enough of 160-200 A.
• The diameter of the electrodes (1.6 to 6 mm).
• Permissible duty cycle at maximum current. This value is indicated as a percentage. For example, if you specify 70%, then after seven minutes of work it is necessary to take a break to cool for at least 3 minutes.

Availability of useful special functions:

• "Hot" start - a quick transition to the operating mode with a temporary increase in the output current.
• "Forcing" - forced change of volt-ampere indicators to improve the quality of the weld joint.
• Voltage "gap" - this setting sets the optimal length of the arc to create vertical seams and perform other special working operations.
• "Antizalipanie" - disables current flow after the automatic set output short circuit formation. In order not to expose themselves to unnecessary burdens check weight.

Reviews help consumers figure out which one to choose welding inverter for home. But the very need to clarify packaging kit, study features of the display and management. A comprehensive analysis is required for the correct choice.
