Welding machines operating from household power supply are convenient in that you can use the device without any additional permits from energy companies. In addition, such devices can safely “coexist” with other electrical devices connected to the outlet. Resanta SAIPA 200 is one of the inverter devices that are also endowed with other positive characteristics.
Types and features of welding machines Resanta SAIPA 200
Resanta SAIPA 200 metal welding machines may have design features that you should be aware of before purchasing a new device. If the letter “C” is installed after the product name, it indicates the possibility of separating the welding torch from the inverter. Thanks to this feature, you can easily replace this element of the device. The standard model is equipped with a non-removable burner.
The main feature of this inverter model is the ability to weld in two modes. The device is suitable for joining metals using conventional electrodes; in addition, it can work with welding wire in a shielding gas environment.
Resanta SAIPA 165: main technical indicators
Let's look at the main indicators of Resant SAIPA 165 and the nuances of welding with it:
- Wire feed is directly dependent on current strength. This helps to avoid current short circuits and arc breaks during welding;
- The current strength is adjusted according to the selected cross-section of the electrode. The higher it is, the deeper the penetration of the metal;
- Welding speed allows you to control the quality and geometry of welding work. At high speeds, the wire has a chance to go beyond the protective sphere and oxidize. At low speeds, the weld pool increases and the likelihood of pores forming in the weld increases;
- The arc voltage is controlled by the selected current value. As this value increases, the penetration deepens and the seam becomes wider. Increasing the value too much leads to metal spattering and the formation of voids in the seam;
- The shielding gas and its quantity depends on the cross-section of the electrode, welding speed and air circulation around. If there is a need to increase gas protection, then the welding speed must be reduced and the nozzle should be brought directly to the surface to be welded;
- The polarity is set in reverse, the burner is connected to the “plus”, and the metal to the “minus”. Welding without gas is carried out in the straight polarity position;
- The inclination of the electrode affects the depth and quality of the seam. If the metal being welded is thin, then it is necessary to tilt the wire forward. With reverse tilting, the depth of the seam increases, and visual control over the progress of work improves.
Design of welding machines SAIPA 200
The semi-automatic welding machine SAIPA 200 has a metal case in which the inverter device is located. The electricity converter is made on the basis of IGBT transistors. These components emit a large amount of thermal energy during operation, so a fan is placed inside the case to direct air flow to the heat sinks of the electrical components.
In order to make the operation of the device safer and more comfortable, light indicators are installed on the front panel of the case. These elements inform the operator:
- About connecting the device to the network.
- About the appearance of overheating.
When the temperature of internal parts rises to the limit values, automatic protection is triggered. This function helps prevent failure of the most important parts of the welding machine. After the temperature has normalized, work on welding metals can continue.
In addition to the display, the device is equipped with adjustments for the operating current and wire feed speed. Thanks to the precise setting of parameters, you can ideally select the operating mode of the device, which will ensure ideal results with optimal use of consumables.
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.

Operating principle of welding machines Resanta SAIPA 200
It is necessary to know the basic principles of operation of Resanta SAIPA 200 welding machines in order to try to avoid excessive loads on the device during operation. The design of an inverter, the “heart” of which is powerful transistors, was previously described. Thanks to the presence of these parts, it is possible to first increase the mains voltage to 400 volts and equalize it. Then, a reverse high-frequency conversion is carried out to a voltage of 15 - 23 Volts. After the transformation, the electric current levels out again.
When the electrical voltage is converted, one of the poles is applied to ground and the other to the welding wire or electrode. Due to the large thermal power released when the contacts are closed, metal elements are melted and connected.
