Description of the welding inverter SAIPA 165
The semi-automatic welding machine Resanta 165 belongs to the class of household single-phase devices that operate on direct current and ensure high-quality joining of metals. Resanta SAIPA 165 can be used with both electrodes and active wire, which greatly simplifies welding. At the same time, regardless of the type of metal being welded, a high-quality connection is ensured, and the weld has additional protection against corrosion.
SAIPA 165 is capable of working with electric current of varying power, which allows you to simultaneously work with thick workpieces of refractory metals, and weld aluminum or other thin metal, which requires minimal electric current power to work with.
Resanta SAIPA 165 was originally designed for use by ordinary homeowners. This device is extremely easy to use , and to turn it on you just need to press the corresponding button on the handle, after which the welding wire will be automatically fed to the welding site. In this case, it is possible to adjust the wire feed speed, the thickness of which can vary significantly, depending on the operating current and the metal parts being welded.
General information
Connecting metal parts to each other makes it possible to realize even the most complex projects. Semiautomatic welding machines can be classified as single-phase devices that perform welding operations at direct current. As for the Resanta SAIPA-165 brand apparatus, welding occurs using wire , which melts in a gas environment. A rather big advantage of semi-automatic welding is that the wire and gas are supplied from the torch simultaneously, unlike a conventional welding machine that uses electrodes.
In semi-automatic machines there is no need to maintain a constant gap between the metal and the wire, since the wire is fed automatically.
Another strength of the semi-automatic welding machine is that it is possible to work with fairly thin metal without burning holes. The welding device has an adjustable wire feed speed , which makes the robot quite easy. If the metal is thick, then you can set the amperage higher and the wire feed speed higher, which will speed up the welding process.
Technical characteristics of the device
Resanta SAIPA 165 can be used for operation in a gas environment without additional gas supply. The popularity of this model of welding inverters among domestic buyers is explained by the excellent performance characteristics of this device.
- The current strength can vary in the range of 20–160 amperes.
- The permissible diameter of the wire used is 0.62 millimeters.
- The weight of the device is 11.5 kilograms.
- Permissible voltage deviations from the nominal value are from minus 30% to plus 10%.

general description
The SAIPA-165 unit is equipped with a cooled transformer with an inverter current conversion system, a special welding wire supply system, a drum with a supply of this wire, a special gun for supplying wire and shielding gas (carbon dioxide or its mixture with argon) into the welding zone and is intended for manual welding works of almost any complexity in semi-automatic mode. A flexible wire of a special composition is used here as an electrode for welding, and instead of a protective flux, which prevents the weld from coming into contact with oxygen and other air impurities, a jet of protective gas is used. Unlike welding devices that use electrodes, this system is better suited for more delicate welding work.
In domestic (especially in private or country houses) or industrial conditions, the need periodically arises to reliably fasten certain metal parts together. This is especially true when performing various repair or construction work. After high-tech inverter welding machines SAIPA-165 became publicly available, these works ceased to be considered particularly difficult, since the weight and dimensions of such a device are disproportionately smaller than previous analogues, and the equipment allows even a novice in this business to produce high-quality welding.
The manufacturer paid special attention to the safety and reliability of the device. Special sensors monitor the temperature of the main working element (transformer) and, if its heating temperature approaches critical, will ensure automatic shutdown of the supply electricity. The operator will need to rest the system for a few minutes, after which the device will restore functionality on its own. The moment of overheating will be displayed on the control panel in the form of a lit emergency indicator light.
The SAIPA-165 electrical welding system is manufactured using the most modern materials and technologies. Its controls are compactly concentrated on the front panel and allow you to control the operating process and state of the unit, as well as smoothly change the operating current and voltage.
Device and principle of operation
The semi-automatic inverter welding machine SAIPA-165 is a representative of the most practical and convenient tools of this kind, thanks to the technological and design solutions incorporated into it by its creators. The inverter system for converting household electrical current into working current has made it possible to significantly reduce the size and weight of the device (only 11.5 kg). All the component elements of the unit were placed in a rectangular case made of thin sheet iron, coated with a dielectric protective compound. The side panel has a door that provides easy access to the welding wire feed system and the spool on which it is wound. A strong handle is attached to the top, making it possible to freely move the device to the desired place, and the flat bottom of the case contributes to the necessary stability of the device on a horizontal surface. The housing has a number of slots for normal circulation of cooling air. There is a special port on the rear panel for supplying shielding gas.
The controls for the SAIPA-165 welding machine are concentrated on the front plastic panel. They are functional, accessible and understandable. First of all, this is a power switch and a smooth rotary control for setting the required operating current. There is also an arc voltage adjustment and two light indicators showing network operation and emergency overheating. As you can see, operating the system is quite simple and even a beginner can handle it quite well.
To supply welding wire and shielding gas, a working extension cord with a special gun is located on the front panel. The gun is equipped with a key, pressing which causes the flow of wire and gas through the nozzle into the welding area. Nearby there is a fastening for the cable, which ensures the closure of the electrical circuit.
In the space under the body there is a drum with a supply of wire and a wire feeding system. The drum allows you to place a fairly significant supply of welding material (up to 5 kg) directly in the device itself. Nearby there is an electromagnetic valve for dosing the protective gas supply.
The welding process is provided by a transformer and an inverter conversion system, which create a working current of the required parameters. This is the main working component of the welding machine. The reliability and performance of the transformer require its constant cooling. For this purpose, the surface of the transformer is made of aluminum with special fins to enhance heat transfer. Forced circulation of cooling air is ensured by an electric fan.
Inverter technology first converts normal mains alternating current into high-voltage direct current, and then converts it back into alternating current, but at a higher frequency. For semi-automatic systems, this current is further converted into direct current, which is used to ensure a burning welding arc.
The welding process itself is similar to the classic one. An electric arc heats the fastened elements and wire to the melting temperature, resulting in welding. The wire, through the nozzle of the feed gun, hits the seam continuously during welding. At the same time, through the same nozzle, shielding gas is supplied to the weld seam, creating an insulating environment to limit excess oxidation and increased slag formation. The built-in automation adjusts the operating current at the moment of ignition of the arc to prevent overloads of the electrical network, as well as at the time of welding itself to prevent the wire from sticking. All this greatly facilitates welding work.
Preparing for work
The semi-automatic inverter welding machine SAIPA-165 does not create problems during storage and transportation, and is also almost always ready for work. Periodically, you only need to replenish the supply of welding wire and replace a separate cylinder with inert gas, which is connected to the device through a special port. The spool of wire is installed in its place, and the end of the wire is placed in the guide rollers. Next, you can plug the device into the outlet, having first set the current and voltage regulators to the minimum positions. Having turned on the network toggle switch, press the gun button to make sure that the welding wire is properly fed from the nozzle. Now you can open the valve of the gas cylinder and set the required welding parameters.
Preparatory work should be carried out in accordance with the technical instructions that came with the device. There are general and targeted safety recommendations, as well as fire safety measures, operating procedures and some other useful recommendations that allow you to operate the welding machine in a safe and gentle manner. In addition, the accompanying documents indicate the conditions under which the user can count on warranty service for the SAIPA-165 welding machine by the manufacturer or its official representative for two years from the date of sale.
Basic equipment of the inverter
The basic configuration of this inverter model raises certain complaints. The Resanta SAIPA 165 welding machine is equipped with a minimum of additional devices, while it has a high cost for its power indicators. For example, the manufacturer does not equip this semi-automatic machine with consumables or a special case for storing it. The kit includes only a ground wire, the inverter itself, a burner with a cable, as well as technical documentation. Today, this model of welding inverter is offered to customers at a price of 18-19 thousand rubles.
Additional equipment of Resanta SAIPA 165
In specialized stores you can find various additional equipment that makes the welding process even simpler and more efficient. First of all, you will need to purchase the wire used , and the manufacturer recommends using such wire with a thickness of 0.6-0.9 millimeters. We can recommend that you purchase the following additional tools and extensions:
- Gas cylinders.
- Gearboxes.
- Magnetic squares.
- Cleaning brushes.
The cost of such additional devices and extensions is not too high, and their use in work can significantly simplify welding work.
The semi-automatic welding inverter Resanta SAIPA 165 has certain advantages and disadvantages. The advantages of this model include significant simplification of welding and excellent quality of work performed. At the same time, it should be noted the high cost of the device, as well as the not very rich basic equipment, which forces you to subsequently additionally purchase various devices to simplify welding work.
