                Welding machines for home and garden

Rating of  the best welding machines for manual arc welding, protective gas welding, semi-automatic and argon arc welding.

Only inverter models are considered, since their performance characteristics (preventing the electrode from sticking, easy to ignite, stably holds the arc) and price are most suitable for home use.

These are mainly well-known and reliable manufacturers: Fubag, Resanta, Wester, Sibrtech and others. We will tell you which welding inverter to choose, but do not rush to rejoice, heading home with a new tool.

To get a beautiful and reliable seam, you will have to study a little literature, perhaps take a couple of lessons from a familiar welder, burn dozens of electrodes and digest more than one metal structure.

How to choose a good welding machine?

The owner of a tractor, a car, a dacha, a house with a subsidiary farm will always have a job welding steel, but calling a specialist at the slightest need will cost a penny. For the installation of the fence alone, the welder can charge more than a good welding machine with a mask and a pack of electrodes (they will disperse in the process of self-training). Maybe even with the gaiters.

To choose the best welding machine for your home, it is important to consider the scope and conditions of its use. One of the first criteria for choosing an inverter is peak welding current. The higher it is, the larger the diameter of the electrode can be used and the thicker metals can be welded. For a reference point, see the table.

Electrode, mm Metal thickness, mm Current, A

1,6 1-2 25-50

2 2-3 40-80

3 3-4 80-160

4 4-6 120-200

5 6-8 180-250

For home use, a device that works with electrodes up to 4 mm in diameter is sufficient.

According the type of welding machines are divided into:

MMA-manual welding (classic) with a coated melting  electrode. One of the advantages: it is suitable for working with metals of any thickness, except the thinnest.

 Disadvantages: the resulting slag must be removed, which is especially inconvenient when welding in several passes. Feature:

when choosing the electrodes, you should take into account the current – alternating or direct. They work with electrodes up to 4-5 mm.

MIG / MAG – consumable-a melting electrode in an inert (MIG) or active (MAG) shielding gas. It is used for joining ferrous and non-ferrous metals.

The electrode in the form of a wire is automatically fed from the coil. The method is applicable only for working with thin metals, it allows you to cook sheet materials with a thickness of less than 1 mm and structures made of a profile with a wall thickness of up to 20 mm.

TIG-argon arc welding uses a refractory electrode with a diameter of up to 5 mm in the atmosphere of inert gas. The consumable is a filler rod (up to 1 mm thick), the electrode itself usually does not melt.

It is used for welding steel, non-ferrous metals, including pairs of dissimilar ones. To work, you need a balloon with argon.

There are universal semi-automatic welding machines such as MMA+MIG/MAG and MIG/MAG+TIG-combine the capabilities of the tools described above will allow you to perform a wide range of work on the connection of ferrous and non-ferrous metals, of different thicknesses, and their alloys.

Also pay attention to:

Duty cycle or load duration – since electronic components operating with a colossal current quickly heat up, household appliances need regular cooling.

Specified in % for 10-minute intervals. For example, 40% indicates that the device can operate at a current close to the peak for 4 minutes, then it needs 6 minutes to cool down (the time also depends on the operating current and ambient temperature). Multiple values can be specified for different amperages.

Protection against power surges shows peak deviations from the norm, for budget models it is in the range of up to 15%.

Current adjustment range – the ability to change the current strength allows you to adapt to welding with any electrodes in different conditions.

It depends on the device, it starts from 5-20 A and ends with the maximum values for it in 180-250 A.

In addition to the main features, beginners will be interested in features such as:

hot start – easier to strike an arc;

the fast and the furious arc – an automatic increase of the current when approaching the electrode with the base metal during firing to prevent sticking;

anti-sticking – after the electrode adheres, no power is applied to it until it is torn off from the surface to be welded;

idle voltage-the parameter shows how easy it is to ignite and maintain the arc: at 80-90 V-even a beginner can cope, at voltage values below 40-50 V-the work will turn into a quest, especially for beginners.

What to choose for home use:

The inverter is a compact, budget-friendly and versatile solution for the home craftsman, irregular use in everyday life;

The semi-automatic machine is a specialized tool for welding non-ferrous and thin metals, alloy steels;

Rectifier-used for working with color met, low-carbon and high-alloy steels;

Transformer – the most common device in the industry, it is advisable to buy for the production of metal structures in large volumes.
