People who deal with welding not at work, but at dachas, in private homes, etc., know how important the quality of the welding electrode is. Of course, with the advent of inverters, welding has become better and easier, but practice shows that a lot depends on the electrode: the amount of slag, the quality of the seam, the quick ignition of the consumable.
Today there are no problems with purchasing these elements - the market offers a huge assortment.
Various models from different manufacturers. Professionals prefer branded products, whose cost is higher than that of ordinary ones.
Good, for example, are the products of the Swedish company ESAB , which produces high-quality electrodes of the same name. The Swedish products are truly excellent rods, although the price is appropriate. Due to the latter circumstance, not every home craftsman will afford to buy an electrode of this brand.
Similar in technical terms. According to the characteristics, consumables today are produced by the Ukrainian "Plasmo Tek" - these are "Monolit RC" electrodes corresponding to the ESAB KO 46.00 brand. Their quality is lower, and the rods are also worse in certain positions related to the welding process, but the affordable price makes the products attractive.
Specifications
The main technical characteristics are welding polarity and type of current. Monolith rods can be used with both direct and alternating current . The polarity can be direct or reverse. With reverse polarity, “-” is applied to the part, and “+” is applied to the electrode. The minus and plus poles are indicated on the welding inverter; they are connected to the part and the rod by wires.
It is important that when welding with electrodes, you can weld in different positions. Using Monolith this can be done without any problems. But the Ø5mm rod cannot be used from top to bottom. An experienced welder will understand what we are talking about. It is important to be able to weld metal structures and workpieces in different positions. It is better to weld from top to bottom with a “Monolith” with a short arc, that is, with a minimum distance between the weld pool and the end of the rod. To ensure maximum quality of the vertical seam, the welding rod must be held at 40−70°. In the lower position, the angle should be 20−40°.
Monolith Professional
Electrodes Monolit Professional E50 are used for manual arc welding of products made of ordinary quality and low-alloy steel. They allow you to work under unfavorable conditions due to the formation of a gas bubble, which neutralizes moisture and creates the environment necessary for welding.

Specifications
The deposition coefficient is 8–9 g/Ah. For surfacing 1 kg of metal, 1.7 kg of consumables will be required. Rods with a cross-section of 2–4 mm allow you to work in all positions except vertical in the direction from top to bottom. To do this, take rods with a diameter of 5 mm.
| Electrode diameter, mm | 2,5 | 3 | 4 | 5 |
| Welding current, A | 50–100 | 60–120 | 120–190 | 240 |
For welding work, direct current of direct and reverse polarity is required. You can also use alternating current at an open circuit voltage of 50 V. Subject to storage conditions, they do not require calcination. Damp electrodes need to be dried at 110 °C for an hour.
Other characteristics
- The electrodes have a rutile cellulose coating.
- Deposition coefficient - 9.5 g/Ah.
- Consumable consumption (Ø3 mm) per 1 kg of deposition is 1.75 kg.
Inexperienced welders often set the wrong current strength on the inverter in accordance with the diameter of the electrode used. Such flaws always have a negative impact on the quality of the weld and the connection itself. Therefore, it is extremely important to correlate the indicators correctly.
If the rod is wet or has been in a damp room for a long time, it is prohibited from cooking! Before welding, be sure to calcinate it for 30 minutes. at a temperature of 120 ° C.
"Monolit RC" are suitable for butt joints. The temporary resistance of the electrodes is 340 N per mm², the smallest inclination angle is 35°. It is also important to note that in this case a rutile coating is used. The greatest angle of inclination is 70°.
Experts say that the consumption of rods of the described brand is insignificant. The diameter of the product is 3 mm. Relative elongation at 22%. Sensitivity to contamination is low. High deposition rate. Rods of this brand can be used for working with pipelines.
“Monolith RC” is sold in 1 kg packs, and the average price is 340 rubles.

Advantages
Monolit has a number of advantages over other brands of electrodes that are often used during the welding process at home. The products were appreciated by both professional welders and amateurs.
This is what we are talking about:
- The rods ignite easily even after repeated welding.
- Stable arc without dips or surges.
- There is no metal spatter during the welding process.
- Ensures that the seam is smooth, rounded and evenly filled.
- The slag released from the coating of the rod can be easily separated from the weld pool area.
- Possibility of using consumables with both professional welding machines and household low-power inverters.
- If during welding you come across an area with a poorly accessible welding line, the rod can be easily bent, but even this way it welds perfectly without flaws.
- For non-critical structures, the rod can be used without preliminary cleaning of the parts to be welded. Welded edges do not need to be cleaned of grease, oil, dirt and rust.
Thanks to its characteristics, “Monolith” allows even a beginner in welding to easily perform welding. The rod does not stick, it welds easily, and there is practically no metal spatter, and the seam is of high quality. Monolith RC electrodes are universal. Can be used at home or in industrial production, and are suitable for any type of welding.

Conditions of use:
Deposition factor – 8.5 – 9.5 g/Ah. Electrode consumption per 1 kg of deposited metal is 1.75 kg. Electrodes of the MONOLITH RC brand are intended for welding corner, butt, and overlap joints made of metal with a thickness of 3 to 20 mm. The electrodes are insensitive to the quality of edge preparation, the presence of rust and other surface contaminants. During installation welding, it is possible to work in all spatial positions without changing the welding current. Welding vertical seams using the top-down method is carried out with a short arc or support. Slag should not be allowed to flow ahead of the arc. To do this, the angle of elevation of the electrode to the vertical should be 40 – 70°. In the lower position, it is recommended to tilt the electrode in the welding direction by 20 - 40° from the vertical.
SPECIAL PROPERTIES: MONOLITH RC electrodes differ from similar products from other manufacturers in the reduced amount of emissions and the intensity of formation of welding aerosol and manganese during metal welding. This was achieved through the selection of high-quality raw materials and a high level of control of technological processes in the production of electrodes. Institute of Electric Welding named after. E.O. Paton NAS of Ukraine and the Institute of Occupational Medicine of the Academy of Medical Sciences of Ukraine have confirmed that the release of manganese is reduced by more than 30%, the release of harmful substances in the welding aerosol by more than 28%.
MONOLITH RC electrodes are distinguished by easy initial and re-ignition, soft and stable arc combustion, low metal loss from spattering, uniform coating melting, excellent formation of weld metal, and easy separation of the slag crust. Allows welding at extremely low currents. For small-diameter electrodes, welding can be done from power sources connected to a household network. Easy handling of the electrodes makes welding possible for novice welders. Welding in hard-to-reach places. Ability to bend the electrode without damaging the coating. Welding on oxidized, oily and painted surfaces is possible.
