Gray background and red letters are the corporate style of welding equipment "Resanta". This is the most popular brand in the domestic market due to the good combination of functionality and equipment cost. Outwardly, all devices are very similar, but there are both for private needs (work in the garage, in the country), and for professional activities. In this rating, we have prepared information on which models are the best for a given manufacturer for specific works.

The best welding machines "Resanta" for domestic needs
To weld the canopy on the gate, repair the gate or create a greenhouse in the courtyard, a simple welding machine is needed, which can be bought by every owner. The equipment should have an adequate supply of power and the ability to use from a household outlet. These properties have the devices below.
Resanta SAI 160 - for all newbies
This is an inverter model, where the transformer and the rectifying unit take up very little space. Due to this, the device has dimensions of 34x14x26 cm, but it is able to cook with direct current.
The device has reliable jacks for connecting cables that do not become loose over time from frequent use. The maximum current reaches 160 A, which is suitable for a metal thickness of 4-5 mm, and the power does not exceed 4.9 kW.
Pros:
- an intuitive current adjustment scale, which suggests the correct diameter of the electrode with increasing amperes;
- performance at 160 A is 70%;
- 4.9 kW power does not overload the domestic network;
- able to cook normally when the current drops to 140 V;
- weight is only 3.8 kg (it is convenient to carry around the yard, you can hang it on your shoulder and work at height);
- the current is reduced to 10 A, so the thin metal is boiled without installing additional resistance;
- the set includes a power plug, cable, belt;
- the electrode is quickly ignited due to idle 80 V;
- functions that facilitate the work of beginners (anti-sticking).
Minuses:
- wide vents stretch a lot of dust inside;
- cable weight only 1.5 m;
- no case;
- does not support the work of electrodes with a diameter of 5 mm;
- the current regulator juts out, making it easy to knock the indicator off with a random touch;
- clothespin weight of thin iron (weak);
- fan of shaky plastic.
Resanta SAI 190K - for any work in the yard
This budget model has a more thoughtful assembly with secured control buttons, recessed on the front panel. Two indicators inform about the inclusion in the network and the presence of overheating.
The device has a maximum power of 190 A and power up to 7.15 kW. Able to work for 4-6 hours every day with short breaks. A mass of 4.3 kg allows welding by hanging it on the shoulder.
Pros:
- the arc ignites without long strikes on the surface;
- stable operation at low current, when other devices can no longer cook;
- there is no spontaneous arc attenuation;
- cooks even an electrode with a diameter of 5 mm;
- no deviations in operation at low temperature (-10 degrees);
- more beautiful streamlined design than the analogs;
- the inclusion of an automatic increase in current during sticking
- tolerates voltage drops;
- Supports work with longer cables with a cross section of 50 mm2.
Minuses:
- short cables in the kit lead to frequent tilting of the device during welding of dimensional products;
- a short power cable requires the presence of an extension cord;
- metal plates in a holder of low-quality alloy, so they can deform over time;
- there is no afterburner adjustment (it is not possible to set the magnitude of the current increase, the value is provided by default by the manufacturer).
The best welding machines "Resanta" for professional activities
Every day, professional welding is required to perform welding work, capable of withstanding continuous loads and having a sufficient set of functions. Here are the most popular devices of this class.
Resanta SAI 190 PN - for containers and frames
This productive model is well suited for assembly activities and the creation of metal structures. The device operates in a temperature range from -10 to +40 degrees.
IGBT transistors deliver a stable voltage that does not “sag” even if the mains supply drops to 140 V. In addition to the current, the front panel can adjust the value of B, which makes it possible to control the seam leg. All controls are protected by a transparent cover.
Pros:
- A current of 190 A allows you to work freely with an electrode of 5 mm, which is optimal for high-powered metal structures;
- digital display helps to set the most accurate settings;
- the device has a well thought-out four-sided ventilation system for improved cooling;
- in addition to the clips for the belt there is a rigid handle for a short transfer in place;
- rotating shoulder hooks included;
- the welder himself chooses the degree of alloying of the filler metal;
- PV 70% is optimal for most installation work, where welding and preparation for joining alternate;
- acceptable weight 6.4 kg;
- the degree of arc forcing is regulated (it is possible to determine how many amps should be given when sticking);
- work from the outlet withstands the machine at 16 A;
- lowering the current to 10 A for the purpose of welding of thin containers.
Minuses:
- weak attachment to the tongs (you may have to twist it yourself);
- it takes time to get used to the sensitive current regulator;
- nuts fixing terminal blocks unscrew from vibration;
- The welding cable is not copper, but copper-plated (inside the aluminum conductor).
Resanta SAI 250 PN - for construction
This is a more “advanced” model of the PN series with an adjustable afterburner of the arc. The magnitude of the current reaches 250 A, which makes it possible to cook with 6 mm electrodes.
This allows you to collect large metal structures from channels, angles and thick reinforcement (connection frames of flood supports in monolithic structures). The power of the device is 7.7 kW, and the dimensions are 42x16x30 cm.
Pros:
- maintains temperature to-25 degrees;
- melts metal 10-12 mm thick;
- overheating protection works very rarely, indicating good cooling;
- works steadily for 8-10 hours every day;
- instant excitation of the welding arc from the touch;
- capable of cutting metal at a maximum current thickness of 6 mm;
- soft arc burning.
Minuses:
- the weight of 7.23 kg already requires placing the device on the floor and only short-term work with shoulder attachment, which is not very practical at height;
- for construction use will have to purchase a cable mass and holder, because the existing has a length of 2 m;
- the cost is about 12,000 rubles;
- large dimensions, inconvenient for limited space;
- high power requires carriers with a thick wire section;
- cable holder and the mass can periodically fall out of the sockets with active rotation.
Resanta SAI 315 - for a full-fledged welding shop
This device is powered by a three-phase network and provides a constant voltage with a maximum current of 315 A. The model capacity reaches 16.5 kW. It is well suited for the everyday fabrication of metal structures (containers, frames, agricultural products, frames). Cooks with electrodes from 3 to 6 mm.
Pros:
- thanks to the idle voltage of 85 V, it instantly ignites the arc;
- melts metal 20 mm thick;
- wide adjustment of the seam leg;
- rigid handle for transportation;
- large display with clear numbers;
- eight-hole perforation for ventilation;
- quiet operation, despite the high power;
- high-quality housing with missing plastic elements.
Minuses:
- a large load on the network, so the connection must be made only to the wiring with a large cross section;
- It needs a stabilizer (if drawdowns are frequent on the line), since it is sensitive to a voltage drop of more than 10%;
- large case is inconvenient for transportation;
