What are the types of welding machines and their applications?

best welding machine
best welding machine

When someone thinks about buying the best welding machine, they may not even know what variety of models there are on the market.

The welding capabilities of the thickness of the metal and the types of alloys depend on the selected equipment.

This review will show the types of welding machines by current sources and welding modes, which will facilitate the selection of products that will best meet future challenges.

In this article:

  • The difference between welding machines by source type
  • Inverters
  • Rectifiers
  • Transformers
  • Types of welding machines depending on the type of welding
  • Devices for manual arc welding MMA
  • MIG/MAG Semi-automatic welding Machines
  • TIG Argon Arc Welding Machines
  • Universal welding machines
  • Spot welding machines
  • Plasma welding machines
  • Gas Welding machine

The difference between welding machines by source type:

To understand what types of welding machines there are, it is worth knowing that the equipment is divided into types of current sources and methods of welding.

The voltage from the mains of 220 V and 6-32 A is not suitable for performing the welding process, so it needs to be converted. The following options have been developed for this purpose.

Inverters:

This is equipment that consumes alternating current from the mains at a frequency of 50 Hz and changes its fluctuations to 100 kHz. In addition, the voltage is rectified twice.

In the end, welding is carried out at a direct current of 30-300 A with a voltage of 50-80 V, which contributes to smooth seams, deep welding, and less metal splashing.

To implement the process in the inverter circuit, there are:

  1. step-down transformer
  2. rectifier unit (diode bridges)
  3. payment with keys
  4. transistors
  5. the second transformer.

From the device comes two cables, one of which is connected to the product, and the second to the electrode holder.

The advantages of the inverter are compact dimensions relative to other sources of welding current, lightweight of 3-6 kg, and quiet operation (pleasant rustle of the electric arc).

Mosfet Inverters:

invertor-mosfet
invertor-mosfet

Welding machines of this type are usually cheaper due to the use of simpler Mosfet inverters.

Transistors were developed about 50 years ago. They are reliable and convert current well for welding ferrous metals.

But they weigh more than their counterparts. Even for the normal operation of the inverter, there should be about 20 such transistors in the electronic circuit (for models with 180 A).

Such types of welding machines have protection against overheating, triggered after reaching 60 degrees, so the models are characterized by a low PV of 30-40%. The loose layout and large details make it easier for the master to access during repairs.

IGBT Inverters:

This is a more modern generation of transistors, which are installed inexpensive welding machines.

The weight of the IGBT is less than its analogs and requires up to 10 units in inverters with a power of 180 A.

All this contributes to even smaller dimensions of welding equipment and weight reduction.

Overheating of the IGBT transistors is triggered after 90 degrees, extending the total time of use of the device.

On the one hand, there are fewer parts in such a welding machine scheme, but on the other hand, they are very small and it is more difficult to replace something.

Rectifiers:

_Full-Wave-Rectifiers
_Full-Wave-Rectifiers

Among other types of welding machines for manual welding, rectifiers are distinguished, which is relatively cheap and can create high-quality seams.

They consume 220 V current from the mains and lower it through a transformer to 40-80 V, and increase the power to 200-400 A, depending on the power of the model. Next, the voltage passes through the diode block and is rectified. The design has elements of start-up and protection.

Cheap welding is carried out by the direct current. The equipment is reliable and durable. There are versions for domestic and industrial use. Suitable for welding ferrous and non-ferrous metals, cast iron. The main disadvantages are a large weight and large dimensions. When they are cooked, the rest of the network is very “drained”, and other devices may not work correctly.

Transformers:

The cheapest types of welding machines are transformers. They consist of two winding’s:

  1. primary
  2. Secondary

The devices operate on the principle of magnetic induction. The distance between the windings helps to increase or decrease the current.

Welding is carried out at alternating voltage. The devices are suitable for joining ferrous metals. They are simple and reliable. Among the disadvantages of this type of equipment are a large weight, a strong hum, high metal splashing, and large dimensions.

Types of welding machines depending on the type of welding

Having considered what welding machines are by the type of power source, we will move on to their varieties by welding modes.

Devices for manual arc welding MMA:

Such types of welding machines are built on the basis of inverters, transformers, or rectifiers.

The best welder welds a holder on which the melting electrode is fixed. The metal rod closes the arc on the product and serves as an additive material.

The outer coating, when melted, creates a gas cloud to protect the weld pool from the external environment.

This type of welding can be used to connect ferrous metals.

If you install the electrodes with a stainless rod, you will be able to weld alloy steel. But the speed of work is slow, you need enough experience to get a high-quality connection, you constantly have to control the length of the arc, as the electrode decreases.

MIG/MAG Semi-automatic welding Machines:

mig-mag-welding-machine

MIG/MAG welding is called a semi-automatic welding machine since the seam is carried out using a burner, but the wire inside is fed from a special mechanism from the coil.

The principle of operation is similar to the MMA, only instead of the holder, a compact burner is provided. The metal is connected by an electric arc (the mass cable is connected to the product, and the “plus” remains on the wire).

Semi-automatic welding machine-MIG/MAG:

Thanks to the continuous feed of the additive, you can create long, neat seams. There is no slag in the weld pool, so it is better for the welder to control it.

Protection from the external environment is provided by the gas supplied from the cylinder through the nozzle of the burner.

This type of semi-automatic welding machine is fast and allows you to connect metal with a thickness of 0.6 to 20.0 mm. Depending on the type of wire to be installed, you can weld black metal, stainless steel, aluminum. But you need to carry a balloon behind you.

Even in the wind and working on the street, the welding bath becomes defenseless (the supplied gas is blown away).

TIG Argon Arc Welding Machines:

TIG-ARC-MMA

TIG welding is performed by inverters. Here, too, there is an electric arc, but it burns between the product and the non-consumable tungsten electrode. The latter is 1.6-3.2 mm in diameter and is sharpened in the form of a sharp cone.

This allows you to create narrow seams. The joints can be made both at the expense of only the fused edges and with the help of an additional additive supplied by the free hand of the welder. The welding bath is protected by argon blown from the burner nozzle.

Argon Arc Welding Machine:

When working on direct current, you can weld ferrous metals and stainless steel. There are types of welding machines with AC/DC function, designed for welding aluminum. So this welding machine is the best welder for aluminum.

With this equipment, you will be able to cook very carefully and economically, but the speed of the method is significantly inferior to the semi-automatic.

Universal welding machines:

Universal models of welding machines combine several welding modes at once.

Here are the existing options:

MMA+MIG. The model is capable of cooking with coated electrodes and wire fed from the drum.

In the first case, it is practical for cutting with electric welding, and in the second for mass production of sheet metal parts or body repair. This quality welder is the best welder for sheet metal.

MIG+TIG. Semi-automatic with the possibility of attaching an argon burner. Allows you to quickly apply seams on stainless steel and black metal using the MIG mode, as well as connect aluminum by switching to TIG and it is the best welder for stainless steel.

MMA+TIG. Inverter for welding with conventional electrodes and tungsten rods. It is practical when alternating welding of ferrous and non-ferrous metals where high speed is not required.

3 in 1. The most versatile machines that can perform welding in MMA, TIG and MIG modes. For this purpose, there are several sockets on the front panel for connecting the corresponding burners. Such equipment is purchased for the most versatile tasks.

Spot welding machines:

Spot welding machines are available in the form of models with pliers for double-sided welding or with a gun and a reverse hammer for single-sided welding.

The first ones are used for the assembly of thin-sheet structures (boxes, doors, gates, gates).

Double-sided spot welding machine

The latter is used in body repairs when it is necessary to weld to the plane without access to the reverse side.

There are hand-held portable models with a weight of up to 16 kg and stationary contact welding machines. The thickness of the metal to be welded varies from 3 to 9 mm.

Single-sided spot welding machine

Plasma welding machines:

These types of devices use an electric arc burning in the nozzle between the cathode and the anode.

Compressed air from the compressor is passed through it, which forms a plasma. Closing the mass on the product allows you to transfer the arc and make it not a duty arc, but a cutting arc. If you use filler wire, this method is suitable for welding parts.

Gas Welding machine:

Gas-Welding-Machine
Gas-Welding-Machine

The apparatus here refers to an acetylene generator that produces gas when the carbide interacts with water.

Additionally, a cylinder with oxygen is connected, which supports Gorenje and promotes the development of the flame temperature up to 3000 degrees. But recently, more often than not, they use not apparatuses, but just two cylinders (acetylene+oxygen or propane+oxygen).

Then for welding, it remains only to purchase a burner and two hoses.

The flame heats up the metal edges, and the filler wire fills the weld pool and increases the seam height.

Gas welding machine:

This method is suitable for welding pipes and containers with a wall thickness of up to 4 mm.

Gas welding machine does not require electricity and can be carried out in the field, but the welding speed is very low, and the probability of deformation of the product from heating is high.

Understanding the difference in the types of welding machines for the current source and welding method, you can choose the equipment for specific tasks, whether it is welding parts in the garage, body repair, or serial production of products in the workshop.

Now you decide which kind of welding machine you will choose for your work?
