The device "Hobby-110" is most small-sized in a class of resonance welding devices. It also differs by extra low energy consumption parameters, that successfully allows to apply it with weak electric systems (garages, summer residences, private houses etc.).

         High technological properties of resonance welding sources are defined as a rule with selective properties of secondary contour loaded on an arc interval. Application of resonance contour in secondary circuit provides practically sine wave form of curve of a welding current.

         The welding equipment of the given class has got following advantages:
- high level of electric safety, provided by special solutions, which limit voltage of a open circuit not more then 38V (in devices produced by special requirements - no more 12V);
- high efficiency (up to 80 %);
- achieving of factor of capacity cosjі0,95 by the simple adjustment of resonant contour;
- minimal level of interferences, generated into network and environment, in comparison with all known samples of welding equipment;
- reduction (!!!) at short circuit in a welding contour of a current consumption from a supply in 1,5 - 2 times (in known types of welding devices it is usual growing in 2 - 2,5 times);
- the absence of peaks of ignition in a curve of current, that allows to reduce the concentration of diffusion hydrogen in a seam and by that to improve its strength properties.
