Today, there is a large number ofmodels of welding machines designed for various operating conditions. When selecting these devices, you should clearly understand where they will be used, and what characteristics are most important.
Increased demand for weldingtransformers. They allow you to work on both industrial facilities and in the home. These devices are fairly simple in their device, have a low cost, and some craftsmen use self-made welding transformers. With their help, you can weld black metals overlap and butt.
Приспособления оцениваются такими свойствами, как the constancy of the welding process, the initial ignition and elasticity of the arc, the quality of the formation of the seam. Accordingly, at higher indices, one can judge about the best possibilities of the apparatus.
When choosing welding transformers,take into account the current strength of the device. According to this indicator, devices for household purposes (up to 200 A), professional (more than 300 A) and semi-professional, operating with a current of up to 300 A are distinguished.
Еще одним показателем, на который нужно обратить attention, is the voltage used. At home and in production, these indicators differ (220 and 380 V). Therefore it is important to know where the device will work. The higher the idling voltage of the device, the faster the arc is fired and stable. The performance also depends on the type of electrode with which the AC welding welding transformers work.
In devices use both thin, andthick electrodes. The most commonly used materials are 2-5 mm in diameter. If there are difficulties in determining the type of electrodes, it is necessary to purchase a universal apparatus that is able to work with any consumables and metals. All the characteristics of the transformer can be found from his passport.
When evaluating the efficiencywelding devices, we can say that this indicator is not high, an average of not more than 80 percent. Welding transformers are not able to perform high-quality seam. This drawback must be taken into account, and for the execution of responsible work it is better to purchase inverter equipment. However, this gap is more than offset by the unpretentiousness of the device and low cost.
The fixtures are fairly simple to use.and this is not inferior to any type of welding equipment. To perform work with the help of a transformer is capable of any person who has at least minimal knowledge of welding. The main condition for the use of the device is compliance with safety regulations and the use of special protection. To ensure the safety of welding, you should purchase a shield or mask that will protect your eyesight.
