Choosing a house welding machine - answers to questions about host

What are welding machines for domestic use?

Household welders are indispensable for the implementation of construction and repair works, when almost every day there is a need in the manufacture of wire mesh, installing greenhouses, automotive body repair, and many other items.

According to the existing classification to the group of household appliances can be attributed to the current strength of up to 200 A, allowing to work with metal is not more than 8 mm.Before you choose which, for example, welding machine to give us needed, consider the existing varieties:

• transformer portable welding machine AC .It is designed for welding ferrous metals, and is best suited for novice welders;
• transformer universal welding machine DC .Used in a wide variety of jobs.They can also be welded non-ferrous metals and stainless steel;
• compact welding machine - semiautomatic.It is used for welding of iron, aluminum and steel.The active element is not a consumable electrode, as in the previous types and the welding wire, which, if necessary, together with the gas (or without) enters the welding point;
• portable welding machine - inverter.It has a low weight (2.5 kg) and minor dimensions.It can work both from independent power supply, and from the power supply.The possibility of fine adjustment of the current strength;
• welding rectifier .It consists of a block of semiconductor rectifier and a transformer.The principle, which underlies his work, allowing even beginners to achieve produce quality seam - a continuous electric arc with a stable characteristic of metal melts evenly.

What we can tell the type of welding machine?

After what has been said above it is clear that the choice of the welding machine, first of all, you should decide, with some metals will be made of the work (this will determine the type of the required instrument), what will be the thickness of the welded surfaces, as well as the quality and purpose of the joint (this will depend onthe power of the selected device current).

When choosing a welding machine is required to be taken into account and the value of the PX index (duty cycle), which characterizes the ability of the machine to continuous operation during the 10-minute time slot to its automatic shutdown to prevent overheating.

So if PV equals 20%, this means that of the 10-minute and the unit will only operate continuously during 2.PV is directly related to the length of the weld.

Why not jump over your head?

When you select a device for home use is very important to set priorities.It is unlikely that a mini welding machine will be able to replace the universal transformer DC.And, in the same way, multipurpose welding machines can not replace welding rectifiers.

also necessary to pay attention for a few moments.It is advisable to buy a welding machine powered by a single-phase network, ie 220 V. In addition, it should be borne in mind that a good household tool consumes less than 5 kW of power and is not sensitive to power surges.

And yet - do not pay for unnecessary functions of the device.Clearly define the purposes for which it is needed.However, it should also be remembered that the machine with a suspiciously low price is really not worth the money.
