About the manufacturer

Latvian concern "Resanta" more than 15 yearsproduces a large number of names of electrical devices sold in the near and far abroad. Trained professionals organize the interrelated work of the design bureau and production facilities in the city of Riga. A well-established production chain exists thanks to the stable operation of marketing and logistics services.

Welding inverter "Resanta SAI 190", which isone of the successful products of the company's products, is popular with consumers and partners. The trust of the manufacturer is earned due to the high quality of the devices, which is checked by the monitoring service at every stage of the technological cycle. Great importance is attached to the use of technical methods of management and control in the work of workshops and sites.

Unit description

To use argon-arc welding,connect the valve burner to the device "SAI Resanta 190". Reviews say that for the implementation of semi-automatic welding get a mechanism that feeds the wire. Pulse modulator adjusts the values ​​of the welding current, so even a novice welder makes a quality weld.

At the time of the appearance of the arc in the apparatus,overload, welding is connected to weak networks with unstable indicators. Due to its low weight, the unit can be carried and transported in the trunk at any distance.

The device operates in a mode of 70 and 30%. The values ​​indicate that seven minutes of work are followed by a three-minute break. The indicator on the front wall indicates overheating, after lighting up the light bulb, check for a short circuit in the circuit, if not, the unit will not use 5 minutes or more for cooling.

Welding inverter is cooled byfans, forming the effect of the tunnel, and powerful radiators of considerable area. Welding operates from a two-phase 220 V network, while current performance ranges from 150 to 243 V. The value of the welding current is set from 10 to 190 A.

Device Features

The "Resant SAI 190 PN" welding is produced according to the modern production technology of IGBT:

• The inverter works productively under reduced voltage in the network;
• a smooth change in the current indices;
• when the electrode touches, a soft ignition of the electric arc occurs;
• The weight of the unit is reduced due to the use of modern power transistors;
• in the design there is a function of hot start, anti-adhesion of the electrode and uniform arc burning;
• The weld pool has a large depth;
• At work the metal is sprayed in a minimum amount.

Technical indicators

All the electric power consumed by the device goes to the work of the arc and to the melting of the upper metal layer:

• the required voltage in the network for operation is 220 V with a deviation of 10%;
• the maximum value of the working current is 25 A;
• value of arc voltage - 27 V;
• forced-air cooling;
• electrodes are used 5 mm;
• class of enclosure protection - IP21;
• the dimensions of the apparatus are 15 x 30 x 37 cm;
• The weight of the unit is 4.7 kg.

The complete set includes an inverter, an electrode holder with a 2 m cable attached, a connection terminal with a 1.5 m cable, a hammer-brush, a protective shield.

Welding machine operating instructions

To household electricity network for connectionInverter has no special requirements. Zeroing of the device takes place through the connection cable, therefore the power supply socket must be grounded when welding the "SAI 190 Resanta" welding. The instruction recommends for connection to put automatic devices not less than 16А.

Near the machine is not used in the workdevices that produce a lot of dust, for example, a Bulgarian, a gasoline and electric saw, a grinding machine. The included unit, even if it is running idle, can not be covered and other obstructions in the operation of the cooling system.

It is forbidden to work by welding in the rain or in very humid rooms according to safety instructions.

If the inverter is brought into a warm room from frost, then turn it on not earlier than a couple of hours, necessary to drain the condensate.

Inverter connection

The unit is connected to the mains withregulator in the off state. Work and power cables are connected to a power outlet or machine. With the help of the regulator set the minimum current for welding, only then the toggle switch is turned to the "on" position. After work, turn off the "SAI Resanta 190" in the reverse order. Customer feedback indicates that for effective work, workers' wires and extension cords are not allowed to cross. The cables are fully deployed from the coil during operation to prevent the occurrence of magnetic induction.

Recommendations for work

Do not often turn off the welding machine, evenif the light is on, just wait 10 or more minutes before cooling down. In the mode of intermittent operation after 7-8 minutes, welding is also not disconnected, and the put 3 minutes of rest are waiting in idle mode. Inverter-type equipment reacts badly even to minor starting currents. Turn off the device if the break is planned for more than 40-60 minutes.

Periodically, cleaning of internal cavities from the accumulation of dust and dirt, especially after a long standstill or work in dusty conditions.

With the extension of the cable, the following sections select a larger diameter, which leads to a decrease in the voltage drop. With an increase in length from 10 m take the cross-section of the wire 2.5.

Cost of welding machine

The price for the purchase of welding ranges fromfrom 6800 rubles. up to 17 600 rubles. The lowest cost is the device with the index "K 65". This is a simple unit for manual arc welding. The device with the "Prof" index is more expensive than all models, it has the ability to work even when the voltage drops to 100 W.

"SAI Resanta 190". Reviews

What do customers think about this device?

Consumers respond positively to their workwelding machine "Resanta SAI 190". The price of the unit purchased in the store quickly justifies itself with efficient operation. Owners of the device believe that it is important to use the device that before starting work and before shutting down it is necessary to set the minimum current value. Regular cleaning will significantly extend the working life.

Welding machine users markthe possibility of equipment to work with a wire feeder for organizing automatic welding with the "Resant SAI 190" unit. Sometimes coolers corrupt, and they have to be changed. Buyers note that, in addition to welding of black steels, the unit works with non-ferrous metals and copes with the work adequately. Consumers consider important the constant concern for the working parts of the apparatus.

As a result, we can say that the use of"Residents" is effective for private homes, villas and small industrial facilities. The connection does not require the replacement of wiring, the unit copes well with work in networks with weak indicators.
