Welding machine "Resanta SAI 190": reviews, specifications, instruction manual

Welding inverters, which are distinguished by ease of operation and ease, have supplanted transformer welding units. Visiting the store, you can make a choice by reading a wide range of welding equipment, represented by dozens of models. They differ in technical characteristics and cost.

Welding inverters appeared not so long ago, in the 70s. last century. As the main difference of such a device from a transformer is the method of current conversion. In the inverter, the alternating current goes to the rectifier and is converted to a constant one. In the next step, the constant is converted to a variable with a high frequency. At the next stage, the AC voltage is lowered. Such conditions are necessary for welding.

High-frequency transformers have compact dimensions, but welding machines can have a weight that sometimes turns out to be significant. When choosing a welding inverter, several factors must be considered, among them:

  • model class;
  • thickness of materials to be welded;
  • intensity and scope of work;
  • Operating conditions;
  • power network.

The design may have a display that displays the performance. The market today presents a huge variety of models, among them the “Resant SAI 190” should be highlighted, the reviews of which you can read below. Opinions of consumers will allow you to understand whether it is worth declining your choice towards this device.

User's manual

Resanta Sai 190 Features

Before you start using the "Resantu AIS 190", the instruction manual must be studied. Among other sections, it covers safety rules.The manufacturer stresses that the operator must protect himself from burns. They can be caused by hot metal, slag and sparks, as well as by arc radiation. All these effects can cause serious damage to the skin and eyes. Therefore, the welder and other people who will be in the work area should use personal protective equipment. This should include:

  • gloves;
  • boots;
  • headdress;
  • mask or welding shield.

Before using the device, it is recommended to wear a flame retardant suit and pants that will cover all areas of the body. Before you start using the Resant inverter, you should be familiar with the rules of its operation. It is important to bear in mind that during work, ultraviolet radiation will be emitted which can damage the skin and eyes. To prevent irreversible effects, you must use a welding mask and protective clothing. The shield should be equipped with a filter with a degree of dimming DIN 10.

Before turning on the unit, it is important to ensure that fire extinguishing agents are available in the near zone of welding.Flame and explosive materials should be removed 10 m or more. It is prohibited to weld closed containers containing explosives or toxic compounds. If such a need arises, then the tank should be cleaned. You should not carry out welding work in an atmosphere where there is a high concentration of flammable gas, dust and flammable liquids.

Reviews about the features of operation

During operation, "Resanty AIS 190" faults may occur. When the “Network” indicator is not lit, you need to check the position of the switch and make sure that the device is connected to the network. If the equipment does not develop full power, then a low line voltage or a wet welding electrode may indicate this.

If you notice that the “Overheating” indicator is lit up, then it may be that the value of the LV was exceeded. Inside the device, the temperature is quite high. In order to continue operation, the device must be allowed to cool. The above-mentioned indicator may also work when a lot of dust has accumulated inside the case. To clean it you need to contact the service center.

Fan Problems
