Which welding inverter is the best to use

Before moving on to the TOP of the best inverter machines, let's look at their varieties in design, principle of operation and scope of use.

Inverter for manual arc welding (MMA)

Principle of operation. Inverters for RDS are carried out in a single housing and differ in compact dimensions within 30x20x15 cm. Most often they weigh 3-6 kg and are convenient for working at heights or along a long structure. The welder simply hangs the machine on his shoulder and moves with it. Inside the inverter there is a step-down transformer, a key board and a diode bridge. Receiving an alternating current of 220 or 380 V from the network, the equipment increases its frequency by a factor of hundreds and converts it into a direct current.

MMA inverters are available with two connectors, to which the holder and ground cables are connected. A clamp with a value of “-” clings to the product. A coated electrode is attached to the "+". Contact closure leads to the excitation of an electric arc. The distance between the end of the electrode and the surface of the product must be maintained within 2-5 mm so that the rod does not stick. The filler metal fills the weld pool, forming a seam. The electrode coating, melting, emits a gas that protects the molten metal from the external environment.

In which case it is better to use. Due to its simplicity and compactness, MMA inverters are often used in the country, in the courtyard of a private house and small workshops. But it turns out to work slowly (you need to constantly change the electrodes, clean the seams from the slag crust), so it is suitable for tasks where the final result and economy are priority, rather than manufacturing time (make a fence yourself, weld a loop on the gate, make a greenhouse, etc.) . d.).

Inverter for semi-automatic welding (MIG / MAG)

Principle of operation. MIG / MAG inverters come in a single housing or separate with a feed mechanism. The wire wound on a babin here plays the role of an electrode, closing the circuit to form an electric arc. But since the additive is supplied continuously from the drum, the seams are long and smooth, without obvious transitions. The welder is equipped with a torch, inside which current, wire and protective gas are supplied.The latter can be inert (argon, helium) or with active protection (carbon dioxide). The advantage of MIG inverters is fast seam execution speed and high quality joints. The absence of slag crust does not require subsequent stripping.

Inverter for TIG welding

Principle of operation. Inverters for TIG welding are very similar to models for MMA, only they have a built-in block for gas supply and a chip for connecting the torch control connector. Welding is carried out by a non-consumable electrode (usually tungsten with impurities). Due to the sharp sharpening and the constant arc distance, the seam is narrow and even. An inert gas (argon, helium) supplied from the nozzle protects the weld pool from the external environment. The surface of the joint does not need to be cleaned and machined.

Such inverters can operate on direct or alternating current. In the first case, this makes it possible to weld stainless and black steel, cast iron. In the second case, excellent seams on aluminum, copper are obtained.

In which case it is better to use. Buy a TIG inverter is practical for the manufacture of structures made of stainless steel or non-ferrous metals. This is in demand at large and small enterprises of the chemical and food industries, car services (repair of bumper arches on SUVs, welding cracks in the crankcase, cooling units), and with the release of heated towel rails.

Universal welding inverters

This inverter category contains equipment that combines several welding methods. For example, there are devices for working with coated electrodes and wire feed from a coil (MMA + MIG). The housing has separate connectors for connecting a semiautomatic burner and an electrode holder.

Such an inverter is in demand for auto repair or metal fabrication, where a high welding speed is required, but occasionally you need to cut something with electric welding or stitch in an inconvenient place (it’s not convenient to crawl with a burner, and you can bend and insert a thin electrode).

There are also MMA + TIG inverters. They can have a full-fledged connector for attaching an argon burner with a button (pressing a key starts simultaneously supplying gas and voltage), or a TIG burner is attached only optionally. In the second case, a valve model is required, where gas is supplied by opening the valve, and to ignite the electrode, touch it on the surface. This is less convenient and suitable for periodic stainless steel welding. With serial production of products, you need to buy an inverter with separate connectors and a built-in burner. The presence of MMA welding will allow boiling ferrous metal 10-20 mm thick if necessary.
