Technologies for performing welding work have undergone significant changes in recent years. If in the past the welding machines used were carried out on transformers, therefore they were bulky in size and difficult to operate, but the advent of semi-automatic welding inverters has made it possible to significantly simplify the work with metal, while such compact units are offered at affordable prices. Inexpensive semi-automatic inverters from the manufacturer Resanta, which combine ease of use and excellent welding quality, are popular on the domestic market.
The manufacturer of welding machines, the Resanta company, is a well-known Latvian company on the Russian market, which uses the latest technological advances in its products and, thanks to the excellent quality of inverters, is able to compete even with the world's leading brands. Domestic buyers love Resanta devices for their ease of use, attractive prices, ease of maintenance, reliability and durability.
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.
Auxiliary equipment
Due to the fact that the welding kit comes with quite a few consumables, as well as personal protective equipment, the user will have to spend money on various additional materials after purchase. A wide range of additional equipment can be found on the market. One of the elements is welding wire of various diameters; if possible, it is also necessary to purchase welding electrodes.
You will also have to purchase a gas cylinder. A brush for cleaning various surfaces will be useful, and for a normal gas supply you need to take a pressure reducer. In the Resanta 165 inverter semi-automatic machine, the pulse feeder often fails, which you will also have to buy or repair yourself.
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%.
- The rated voltage in the electrical network is 220 volts.
The semi-automatic machine SAIPA 165 is intended for spot welding, so we do not recommend using such equipment when performing large volumes of work. If welded correctly, Resanta SAIPA 165 will provide a strong and neat seam , and the metal at the joint will be perfectly protected from corrosion. It is only necessary to compare the characteristics of the operating current with the parameters of the wire, select the correct thickness and feed speed, which will guarantee a high-quality welded joint.

Resanta line of welding machines
What are Resanta semi-automatic welding machines? This is a category of popular welding equipment that belongs to the budget sector and successfully combines quality, reliability, and ease of operation.
Additional advantages include compactness, simple and intuitive controls, low weight, and stable welding quality.
The design is made in a metal case, which has an opening wall. The front panel is equipped with a regulator for the operating current, indicators for “network” and “overheating,” as well as a regulator for feeding the welding wire. An active ventilation system is provided.
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.
Features of the device
First of all, the device has an ergonomic design. Quite convenient regulators, which are controlled with minimal power consumption. During welding, the arc is uniform, which prevents the wire from sticking. The Resanta Saipa-165 device has overheating protection ; as soon as the device overheats, the protection will automatically work and de-energize the semiautomatic device. The features of the model include a strong and reliable ground wire, which ensures proper contact.
The semi-automatic device has built-in special protection against power surges, which is a definite plus. The presence of the “forced arc mode” function, which saves parameters as the arc distance increases, also makes it easier for the robot. The machine can use welding wire with a diameter of 0.6−0.9 mm, which allows you to make a high-quality and durable seam of thin metal.
There is another newer model, this is the “Saipa 220” inverter, the model is also manufactured in Latvia. The inverter can be used both in professional and amateur welding.
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.
