Rules for the choice of the welding machine for home - the types of models and functions

not only a welder, a professional can work with such a device.They are not difficult to use in everyday life, without special training, if properly pick up a welding machine for the home.Here's how to do it.

All welding machines are divided into electric and gas.However, the gas appliance is less suitable for "home and family".Firstly, the need to comply with the necessary requirements for the storage of gas cylinders.Second, safety during welding to provide considerably more complicated.Therefore it is necessary to choose all the same to electric welding.

models welders different power supply current.For domestic products, it is up to 200 A. The "welding" is of several types:

1. units (with power generator);
2. transformers;
3. inverters with frequency converter;
4. rectifiers.

unit

This model it is easy to move from place to place, as its frame has a "slide".They can weld even the "stainless steel".The structure includes the engine and generator, which provides the necessary tension.Such a device is useful where no industrial electricity.For example, a "new building" below the village.However, these products quite a lot of weight, and the cost is also high.

Transformer

Provides work using an electric arc welder from the mains.It is considered quite popular with the mass market.However, he has a lot of weight and dimensions.But it is "compensated" by the low cost.Easier implementation - semiautomatic.However, this option requires some experience.

Rectifier

most suitable model for the novice welder "welder".It gives a stable continuous arc that allows to make a smooth seam quality.

Inverter

This high frequency apparatus.It is compact and lightweight.However, the presence of the electronic frequency conversion circuit makes it less reliable.

Selection Criteria welder

• electricity consumption."Home" device should not consume more than 5 kW.Taking a more powerful, with a margin, it is not necessary, as its price is much higher, and all "opportunities" are unlikely to be used;
• stability when voltage drops in the network;
• for an inexperienced welder need to choose a model with a "hot start";
• for a welding voltage is calculated.Some models are made to operate on 220 V, the other - 380. Preferably the product, which can operate either on one or the other strain.We must bear in mind the fact that the devices are on the 380 single and three phase.Three-phase welding products get better, but they significantly increase the load on the network.Therefore, their use has limitations;
• type of electrode to work;
• the maximum thickness of the resulting weld.Practice shows that in everyday life rarely have to deal with the metal thickness of 5 mm.Therefore, it will be enough machine with an output current not exceeding 160 A. The electrodes with a diameter greater than 4 mm are used very rarely.
