The process of welding metals involves the permanent connection of individual elements through communication at the interatomic level. There are many types of fastening parts through different types of energy conductors, among which the best devices for working at home include inverter welding , the power source of the device is a welding arc.
Purpose and principle of operation of the inverter
The source of electrical energy for welding metals ensures easy ignition of the electrode and supports the constant burning of the welding arc, forms the stability of the work process to electromagnetic interference and voltage drops in the electrical network. By design, all inverter welding machines have a similar circuit, with the exception of the current-voltage characteristic.
Resanta inverter welding belongs to a type of power units designed to stabilize the voltage at idle to the required level. Current rectification is carried out by a block of power electrical circuits containing chokes and IGBT or MOSFET transistors.
The operating principle of the welding machine is as follows:
- The rectifier is supplied with direct current.
- The power inverter module converts the mains current into alternating current at a higher frequency.
- The voltage is transferred to the transformer.
- After conversion in the transformer, the current is supplied to the welding contact.
A household appliance, the functionality of which allows it to be used privately , operates from a single-phase network with an input voltage from 140 V to 260 V, and consumes no more than 4.9 kW/hour. The device is equipped with an overload protection system (class IP 21) and has an increased insulation level (H).
The package includes:
- Cable 3-core, cross-section 2.5 sq. mm (2 m).
- Cable with a cross section of 10 sq. m with grounding terminal (1.5 m).
- Plug for European socket.
- Electrical holder with cable cross-sectional area 10 sq. mm (2.0 m).
- Passport.
- Transport strap.
In the manufacture of the portable household inverter unit Resanta 160, only high-quality materials are used, the internal parts are protected from mechanical damage by a metal case with a rigid frame. To protect against overheating and the influx of air mass, there are ventilation through holes ; the current strength is selected by turning the regulators located on the front panel.

The examination is carried out at the expense of the seller. You have the right to be present during the examination. If the examination reveals the presence of deficiencies that did not arise through the fault of the store or manufacturer, you are obliged to reimburse the store for the costs of conducting the examination, as well as the costs associated with its conduct.
Advantages and disadvantages
The advantages of the inverter-type welding machine Resanta 160 and Resanta 160a, reviews of which are overwhelmingly positive, include a number of indicators that are not found in analogues of other models. The improved design of parts and modern technologies for the production of power elements helped to obtain a compact device for connecting metal workpieces.
The household inverter has:
- Compact dimensions 13.0x19.5x31.0 cm.
- Light weight 4.5 kg.
- Affordable price.
- Durability.
- Reliability when equipped with an IGBT module.
- Improved dynamics of welding arc characteristics.
- Increased efficiency.
- High performance.
- Silence.
- Minimal spattering of hot metal.
- Smooth adjustment of operating parameters.
- “HOT START” or “quick start” function.
- Operating mode: at air temperature −10…+40 C.
Along with the advantages, the unit for working with metal has disadvantages that affect not only the operating parameters of the device. The device requires careful handling and does not tolerate vibration well when transported in a car. In addition, the device requires periodic sanitation of the interior due to dust and small debris entering through the ventilation holes.
The main disadvantages of the inverter are:
- limitation on load factors due to circuit overheating;
- sensitivity to environmental humidity and condensation in the housing;
- workflow failure due to interference from high-frequency electromagnetic waves;
- increasing the cost of the device when solving problems with interference by synchronizing electromagnetic waves with rectifiers or pulse-width modulation.
According to the principle of operation, the inverter is a device with manual arc type MMA welding. The device connects working elements with a piece electrode d = 4 mm, the quality of the weld is observed at a maximum voltage of 160 amperes. An important feature of the equipment is:
- hot start “HOT START”;
- heating the metal until it melts without pressure;
- no anti-stick effect due to the “ANTI STICK” function;
- presence of a warning light on the unit body.

Preparation for use
For welding work using an inverter-type machine, no special training is required; it is enough to study the instructions, select a reverse or direct circuit for the power and grounding cables, and connect them to the correspondingly marked terminals. After preparing the device for operation, you need to check the position of the power switch (the “Off” position), connect the plug to a 220 V power outlet.
Before putting the device into operation, it is necessary to set the current regulator to the minimum value , then switch it to the “On” mode, set the desired current value in accordance with the characteristics of the electrodes. Turning off the equipment is done in the reverse order.
Manufacturers of modern resonant inverters are Russia and China.
Reviews about the application
I conducted a series of tests on a friend’s device and liked the functionality and stability of the inverter. I advised my friend to buy longer cables, since I find it inconvenient to carry equipment when welding structures. Resanta 160a sai will not let you down if you choose the right electrodes.
Vitaly, Ulan-Ude
My Resanta does not act up when voltage surges in the electrical network from 220 V to 180 V, the downside is the impossibility of using electrodes without calcination, they form splashes and do not form a seam. I have no complaints, I use it with pleasure.
Mikhail, Omsk
