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.

The inverter "Resant SAI 190", which is one of the successful products of the company's products, is popular with consumers and partners. The trust of the manufacturer has earned due to the high quality of the devices, which is checked by the control 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 shops 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. The 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 is avoided, welding is connected to weak networks with unstable parameters. 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%. Values indicate that seven minutes of work are replaced by a three-minute break. The indicator on the front wall indicates overheating, after lighting up the light bulb, check for the appearance of short circuits in the circuit, if not, then the apparatus does not use 5 minutes or more for cooling.

The welding inverter is cooled by means of fans that form the tunnel effect, and powerful radiators of considerable area. Welding works 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 construction there is a function of hot start, anti-adhesion of the electrode and uniform arc burning;
• The weld pool has a great depth;
• When working, the metal is sprayed in a minimum amount.

Technical indicators

All the electric power consumed by the apparatus 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;
• 5 mm electrodes are used;
• 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 cable of 1.5 m, a hammer-brush, a protective shield.

Welding machine operating instructions

There are no special requirements for connecting the inverter to the household electrical network. Zeroing of the device takes place through the connection cable, so 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 device do not use devices 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 obstacles in the cooling system.

It is forbidden to work by welding in the rain or in very humid areas according to the 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 with the regulator 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. Feedback from users suggests that for effective work, workers' wires and extension cords should not be crossed. 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, even if the light is on, just wait 10 or more minutes before cooling down. In the mode of intermittent work 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 clean the internal cavities of accumulation of dust and dirt, especially after long periods of inactivity 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 the welding machine

The price for the purchase of welding ranges from 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 consumers think about this device?

Consumers positively respond about the work of the welding machine "Resanta SAI 190". The price of the unit purchased in the store quickly justifies itself when working efficiently. 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.

The users of the welding machine note the possibility of the equipment to work with the wire feeder for organizing automatic welding by 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 with dignity. 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, cottages and small industrial facilities. The connection does not require the replacement of wiring, the unit copes well with the work in networks with weak indicators.
