Welding inverters are devices that make the job much easier for both professional welders and hobbyists to do something around the house using welding. Such a device has a significantly lower weight in comparison with any other welding devices. Welding inverters http://svarka-ua.com/catalog/svarochnye_invertory are equipment that is much more productive than classical welding equipment.
How does this machine work?
With the help of the alternating current existing in the consumer network (with a frequency of 50 Hz), the rectifier is supplied to the rectifier, as a result of which the rectified current is smoothed by the filter, while the received direct current is converted by the inverter using transistors with a relatively high frequency of communications, into alternating current, the frequency of which reaches 20-50 kHz. As a result, the alternating voltage becomes in the range of 70 - 90 V. The current, as a result, also becomes greater, just necessary for the welding process in the range of 100 - 200 A. Thanks to the high frequency, it is possible to achieve significant results, and therefore advantages, welding inverter, which, unlike other sources, is designed to power the welding arc. The inverter machine converts the strength of the welding current to the desired value using high-voltage currents, in contrast to transformer machines that convert EMF in induction coils.
The advantages of welding inverters.
- Of course, the biggest advantage is its low weight.
- Ability to use alternating and direct current electrodes for operation. This is an important point, because it makes it possible to work with non-ferrous metals, as well as cast iron.
- The ability to adjust the welding current. It allows the use of non-consumable electrodes for TIG welding.
- There is a "Hot start" function, which allows you to ignite the electrode with the maximum current.
- The presence of the Anti-Sticking function makes it possible to reduce the welding current to a minimum so that the electrode does not stick when it comes into contact with the workpiece.
Of course, it is worth noting that the price of this invention is an order of magnitude higher than analogs that are used for welding metals.
