Special properties

A distinctive feature of MONOLITH RC products is the low intensity of aerosol and manganese formation during welding. Thanks to this, the product compares favorably with other brands of electrodes. The developers managed to achieve this result through the correct selection of raw materials and careful control over the technological and production process.

High quality indicators have been repeatedly noted by the country's leading scientific institutes. It is the MONOLITH RC electrodes that produce 30% less manganese and 28% less harmful substances in the aerosol.

MONOLITH RC products provide easy initial and re-ignition, as well as stable and soft arc burning. When using electrodes of this brand, it is possible to reduce metal loss due to spattering. It is possible to achieve excellent weld quality, uniform melting of the coating and good separability of the slag crust.

When using MONOLITH RC electrodes, welding can be carried out even at extremely low currents. If we are talking about using products of small diameter, then an ordinary household network can become a power source for them.

The electrodes are very easy to handle. Even young specialists can work with them.

When bending the electrode, the coating does not break. For this reason, they are convenient to use for welding in hard-to-reach places.

The products can be used when connecting metal to painted, oily and oxidized surfaces.

Welding modes

For welding, it is allowed to use direct current of any polarity (the desired polarity of the electrode is reverse “+”, or alternating current of a transformer with an open circuit voltage of more than 50 V.)

They have a basic coating with the addition of iron powder, which increases the efficiency of use by 20%. In application, they are characterized by a higher deposition rate - 10.5–11.5 g/Ah and reduced consumption - 1.58 kg. The finished seam has high strength and metallurgical purity, where the hydrogen admixture is minimal. Metal transfer occurs in a fine-droplet manner, which allows you to lay an even seam without slag getting into the weld pool.

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.

Reviews from welders

According to reviews from welders, Monolith electrodes are the best choice for those who are just trying to weld. They consistently catch the arc and produce an excellent seam. It is noted that they absorb less moisture than products from other manufacturers. Reducing toxicity is an important factor when working indoors. You won't have to breathe harmful gases.

Monolith electrodes are pliable in the welder’s hand. They light up immediately: just swipe across the metal and get a spark. With full coverage and the required modes, there is no sticking. With strong pressure, the materials of the two parts fuse, which makes the seam strong.

Novice welders complain that the arc is interrupted, after which it is difficult to restore it. But it’s not the electrodes that are to blame here, but the lack of experience and too high a current. Welding professionals and self-taught people note that Monolith products are a reasonable price-quality ratio.
