For high-quality and reliable connection of metal details it is the best of all to use welding. To carry out similar works in house conditions, it is necessary to know how it is correct to choose the welding machine. Generally, there are two main groups of such equipment: gas and electric. Welding machines of the first type very bulky and unsafe therefore they are not suitable for house use. For this reason we will consider the equipment working from electricity.
What welding machine to choose?
Today rather wide range therefore it is important to know purpose, pluses and minuses of the most widespread devices is presented at the market of the equipment.
- Inverter. This welding device which operate automatically. They have function which limits input power. Inverters are universal devices which can process any metals and in any conditions. Interests many how to choose the welding machine the inverter, and so it would be desirable to give advice that it is necessary to choose devices with good protection against power surges. Such equipment has the high efficiency, small weight, and still it allows to receive quality result. To minuses it is possible to carry the high price and instability to dust and external damages.
- Welding transformer. To understand what welding machine to choose for the house, It is necessary to tell that the simple design, reliability and the low price belongs to advantages of such unit. It is easy for them to use for performance of welding of ferrous metals both with an overlap, and end-to-end. This type of welding machines the most widespread also works it at alternating current. Transformers are suitable for works when the quality of a seam is not of particular importance. Generally they are used for welding of fencings, lattices, gate, and even for installation of various metal designs. It is possible to carry low efficiency to shortcomings, so the value seldom exceeds 80%, impressive dimensions and weight. Beginners can have problems with deduction of an optimum arch.
- Welding rectifier. Saying about how to choose the welding machine, it is impossible to miss this type of the unit as he allows to receive high quality of work even at initial skills. The rectifier includes the power transformer, the vypryamitelny block and also the protective, izmelchitelny and puskoreguliruyushchy equipment. The high quality of welding is caused by an opportunity to support a continuous and stable arch. It is possible to use for work, both with color, and with ferrous metals. To shortcomings it is possible to refer instability to overheating, high power loss and the price.
- Automatic welding semiautomatic devices. Such devices can be used only in the special environment where there is an inert or active gas. Semiautomatic devices are applied to work with different types of steel and aluminum. Only professionals can use such equipment. Semiautomatic devices allow to receive a quality seam. Good performance belongs to advantages. Minuses: the big sizes, high cost and need to fill a gas cylinder.
- Welding generators. Understanding how to choose the welding machine for the house, it is impossible to miss this version of the equipment as in it both welding installation, and small power plant connects. Such equipment can work in the autonomous mode, so, it can be used in places without power supply. Fine option for carrying out construction works. It should be noted high quality of seams also. It is possible to carry the big weight and the high price and also complexity in service to shortcomings.
