Inverter technology for welding metals rightly occupies a leading position in this vast area of metalworking. This leadership concerns both industrial (including high -tech) welding, and episodic use in the repair business or for personal needs. The advantages that are characterized by modern welding inverters of Svarog and other representatives of these devices are really numerous:
High power with small sizes;
Small weight and simplicity of settings;
A lot of convenient functions that significantly facilitate the daily “welding life”;
Good quality of welding with various spatial orientation of the seams;
Ease of work and the possibility of rapid development by beginner welders;
A low consumption of electrode material and compatibility with various types of electrodes;
Significant assortment of devices, the choice of models of a specialized or universal nature;
Very welding opportunities for different types of alloys differing in thickness and configuration of workpieces.
As you can see, the list of inverter advantages turned out to be a representative. However, it should not be believed that with the advent of welding inverters in the industrial equipment market, all other types of devices and installations went to museums and were commissioned. Firstly, there is a certain inertia of technological thinking, not everyone is ready to change the usual hardware solution. Secondly, it is not easy to embed updated equipment into extensive and extensive technological chains. Thirdly, inverter technique is by no means ideal and has characteristic disadvantages.
The main drawbacks of most welding inverters include:
Price. Inverter welding equipment is much more expensive both rectifier and transformer models of comparable power and performance. Large -scale updating of devices for welding may not elementarily compatible with the budget of the enterprise, and it is possible to replace equipment in parts not always. If routine work is performed, if the requirements for the quality and productivity of everyday welding are moderate, if the increased electricity and electrodes consumption is acceptable, proven rectifiers/transformers are able to continue the “welding service” for many years. Which, in fact, is happening at many enterprises with episodic repair welding, in cooperatives and small workshops, and t. D.
High cost and complexity of repair. The principle of the design of inverters for welding metals involves the presence of a basic power unit – a module of powerful IGBT transistors. Going out of this “inverter heart” will require repairs worth from 30 to 60 (!) interest on the price of a new apparatus. It is good if the breakdown occurred during the warranty period, then the costs will only affect the replacement time and nerves for its provision. Extraurranty repairs of the IGBT unit will be expensive, and replacing branded power transistors with their handicraft Chinese analogues – a uniform sentenced for the failed apparatus.
Restrictions on weather and production use. The more operating modes, functions and adjustments in inverter equipment – the more tender to vibrations, temperature differences, dust and humidity, etc. p. This quality should be taken into account during installation and welding and follow the recommendations for cleaning filters, blowing protective grilles and other mandatory maintenance measures. Otherwise, your inverter will fail without developing part of its resource, and this breakdown will not in any way enter the category of “warranty obligations of the manufacturer/seller”.
