How and what electrodes to choose for inverter welding? Overview, features, types and reviews

Welding is now a demanded processas in the work of professional masters, and domestic professionals. With its help it is possible to fix metal products, and also, if necessary, to create new ones. To ensure that the quality of the seams was decent, you need a minimum experience with the welding machine. Not the least role is played by properly selected consumables.

Therefore, many novice welders are interested inthe question of which electrodes to choose for inverter welding. Take this process responsibly. The advice of experienced masters will help to understand the difference between the presented material and choose the best option for each type of work.

Characteristics of inverter welding

Before selecting electrodes for inverterwelding, you need to familiarize yourself with the features of this process. It involves the use of special equipment. The inverter is a welding machine that uses the melting method for arc welding.

Advantages of this technique in comparison withtransformer varieties have long been appreciated by professional masters. Inverters are now used much more often than other types of equipment. This is due to their stable welding current. It thus turns out very durable and qualitative.

The inverter unit, equipped with a rectifier,It is able to form a constant and alternating voltage at power-on. If there is no mains filter, only a constant voltage is output. This feature must be taken into account when carrying out work.

When using an inverter in its work, it is necessaryto familiarize with its scheme of action. The main consumables of this equipment are electrodes. They are made in the form of a metal rod, through which the current approaches the working surface. When studying which electrodes are best for inverter welding machines, it is necessary to go deeper into the scheme of the equipment operation and the process.

When operating the inverter, otheradaptations. These include a control system, a mains filter (or rectifier), a transformer, and a frequency converter. This allows the device to work with different materials. Even the same installation instance suggests using different electrode grades when welding different materials. Therefore, their choice should be given special attention.

Essence of electrodes

Studying the question of which are better electrodeschoose for welding inverter, you should familiarize yourself with the device of this consumable. As already mentioned above, the same model of the device is used in different conditions. Therefore, the electrodes must be selected according to the working process.

Most modern productionproduces its products in the form of consumables for manual arc welding inverter. This tool is made of metal wire. This rod is treated with a special coating by means of a compact. It is designed to ensure the stability of combustion, as well as protect the welded bath from the effects of atmospheric air. Materials for the production of such products are used very differently. The production standards for electrodes are regulated by GOST 2246, approved in 1970.

Varieties

Deciding how and what electrodes to choose for weldinginverter, it is necessary to refer to the above-mentioned GOST. It states that there are three types of consumables suitable for such works. Electrodes can be carbonaceous, alloyed and highly alloyed. They are made of different types of wire.

A beginner going to produce an inverterwelding at home, it is not necessary to delve into such varieties. It should only be noted that all the electrodes are divided into two large groups. The first category includes materials intended for responsible structures, and to the second category for conventional ones.

If welding is not involved in the creation processbearing metal structures, which will be subjected to significant pressure, then we should give preference to simple varieties of products. When using an inverter for economic needs, this will be quite enough.

Overview of household electrodes

Professional masters are ready to share their experienceand talk about which electrodes are better for a welding inverter. Overview of the most popular varieties will allow a newcomer to choose the right variety of products. To date, the most popular electrodes for the inverter used in domestic conditions are ANO, MR-3. On their characteristics should be discussed in more detail.

The first type of electrodes do not cause problems inprocess of work. They are easily ignited without requiring preliminary calcination. For a novice welder, the ANS is the best option. MP-3 is considered a universal consumable. It allows welding even on rusty, dirty coatings, as well as in wet conditions.

Overview of professional electrodes

Studying which electrodes to choose for weldinginverter, for responsible varieties of designs, it is necessary to choose brands such as MR-3C, and also SSSI-13/55. They are classified as a group of consumables used to create responsible structures.

With higher requirements to the quality of the finished seam, it is better to give preference to the brand MR-3C. Such electrodes are used in metal processing with a constant, alternating current of reverse polarity.

For particularly important jobs when weldingBearing structures should choose consumables brand SSSI. However, only a professional master can work with them. For the beginner, the capricious character of such an electrode will not be to the teeth. But, having learned to handle SSSI, it is possible to create the most durable seams with high density (even in low-temperature conditions).

Variety of metal

When studying which electrodes to choose for inverter welding, you need to pay attention to the type of working material. For each metal, there are different types of welding rods.

For cast iron it is necessary to give preference toelectrodes of the type OZCH-2. Their production is regulated by GOST 9466 from 1975. If it is necessary to work with low-carbon steel, it is better to purchase ANO-4 products with rutile top layer or ANO-6, which have ilmenite type of coating.

Conventional carbon steels require the use ofelectrodes OZS-4, МР-3С, МР-3, УОНИ13 / 45, АНО-21, etc. Stainless and high-alloy steels need the use of consumables for inverter welding under the brand ЦЛ-11.

How to choose an electrode

Having considered what are the best electrodes forInverter welding, it is worth saying a few words about the features of their purchase. First of all, it is necessary to pay attention to the composition of the coating applied to the product. This information can be found in the instructions for use. This will allow you to select the desired variety in accordance with the type of material.

Further in the accompanying documentation it is necessary to consider the deposition coefficient. Depending on the scope of work, as well as the flow rate, the required number of electrodes is acquired.

Also, do not buy products that are nothave appropriate quality certificates. This can be unsafe. The quality of the joints when using questionable materials can be very different from the desired result. Therefore, the process of choice and purchase must be taken responsibly.

Having considered what electrodes to choose for weldinginverter, even a novice master will be able to acquire the correct variety. Work in this case will be quickly and safely. The result will be good even for a beginner.
