Electrodes Monolith: reviews, characteristics, advantages

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.)

Welding electrodes UONI-13/55 PLASMA

Type of coating – basic with iron powder

TU U 28.7-34142621-001:2008

Purpose and scope

UONI-13/55 PLASMA are high-quality electrodes that can be used for welding work in any spatial position. They are suitable for pipelines and critical structures. Products made from low-alloy and carbon steels having a tensile strength of 500-640 MPa can be processed. Electrodes become an ideal option when joint resistance to hot cracks is required. Most often, the products are used in ship repair, shipbuilding, bridge construction and for the manufacture of vessels resistant to high pressure.

Cook in any position, do not clean the parts to be joined, do not calcinate the electrodes and do not worry about observing strict rules for their storage - this is the minimum list of advantages associated with Ukrainian-made products. MONOLITH electrodes of the STANDARD series are deservedly considered universal consumables. They are actively used by both individuals in everyday life and in production. What makes them so popular and suitable for solving the most diverse problems?

Basic information

STANDARD electrodes are designed for arc welding with alternating/direct current, manually and in all spatial positions. The only exception is consumables 5 mm in diameter. They fail to form connections by moving the electrode from top to bottom. Otherwise, STANDARD is ready to create critical and ordinary structures from steels with low carbon content. The maximum thickness of processed metals is 20 mm, the minimum is 3 mm.

MONOLITH STANDARD electrodes allow you to quickly form high-quality fillet, lap and butt welds. In this case, there is no need to change the welding current parameters or clean parts from rust or dirt.

Of the negative aspects of operation, only the nuances of welding vertical joints can be highlighted. When moving the electrode from top to bottom, you need to either use a short arc or achieve deep penetration (support method). It is important to prevent slag from flowing ahead of the arc, which is achieved by constantly monitoring the angle of elevation. The latter should be 40-70 degrees.

Distinctive features

During welding with MONOLITH STANDARD electrodes, a low intensity of manganese and aerosol release is observed. At the same time it happens:

1. Simple and fast starting/re-ignition of the arc, its subsequent even combustion.
2. Reduced metal losses due to minimal spattering.
3. High quality indicators of the finished connection.
4. Easy and complete separation of slag crust.
5. Ability to operate at minimally low currents.
6. Easy to use.
7. Easy and simple welding of workpieces with painted, oxidized or oily surfaces.

MONOLITH STANDARD are suitable for welding in hard-to-reach areas of structures. The coating of the electrodes does not crack when they are bent, and arc burning does not deteriorate. As for small-diameter consumables, to work with them it is enough to power the welding machine from a household outlet.

Characteristics of Monolith electrodes and their main advantages

The manufacturer's electrodes have many fans and those who categorically dislike them.
This is due not only to personal preferences, but also to the fact that they often try to fake materials. You can only be sure that what you are brewing is original if you made a purchase from an official representative. This is exactly what our online store Welder Buy is. Among the many advantages of this Monolith, it is definitely worth highlighting:

• Electrodes can be used to cook with both direct and alternating current. This is a big plus, because... You don’t have to worry about whether they will fit your welding machine.
• Minimum amount of slag. Not only is there little of it, but it also lags well behind the surface.
• Fast and trouble-free ignition. This is especially true for professionals with little or no experience. The main thing is to follow the storage rules and not allow the materials to be exposed to high humidity.
• Lack of a lot of sparks. Minimal metal spattering allows you to keep the surface of the workpieces being welded clean and save yourself from unnecessary problems.
• Fumes when welding with Monolith are much less toxic than when working with other electrodes. This factor is especially relevant for those who cook often and a lot, and at the same time care about their health.
• Affordable price. The price of Monolith electrodes is quite affordable. Especially when you compare them with similar materials from other manufacturers.
