Best TIG Welder Reviews in 2020 – Pick the Right One For Your Project

TIG welding is an extremely popular type of process among professionals. TIG stands for Tungsten Inert Gas because this welding machine uses Tungsten together with an inert gas to weld. Welders use this method for various tasks. However, some TIG welders are better for performing a specific project than others. In this guide, you will have all the needed information to pick the right one for you.

How TIG Welders Work

Before comparing all the different machines, it is essential for the reader to understand the process. Therefore, I will write some basics facts about TIG welders so you will be able to compare the machines more effectively.

Tungsten is the metal from which the electrode rod of the welder is made and, unlike the traditional MMA arc welding machine, it does not reach the melting point, which is at 3,422 degrees, and therefore does not wear out. Its task is to ignite an incandescent arc that fuses the two lips of the metal, or metals, to be sewn so that they weld together as soon as they cool. This system does not make use of additional filler material, as in the electrodes of the MMA system where it is incorporated, and if it is welded with the help of a third material, it must be added separately, during welding, by coupling to the filler metal bar system.

The inert gas, on the other hand, has the task of protecting the melt bath from oxidation. This gas, unlike the oxygen used in other types of welding, preserves the liquid metal from a gaseous combination that would lead it to weaken. Generally, the gas used is Argon, at least for surface type welds. If, on the other hand, you have to work in-depth on materials of medium or high thickness, or alloys with high electrical conductivity, such as aluminum, or copper, then it is better to use helium. Gas has a cost, so the first rule is to avoid wasting it. The combination of gas and tungsten is done through a device called a torch.

What Factors Should I Consider Before Buying

Several criteria are to be taken into account to better choose a TIG welding station. Whether it is on the functional level or the capacity level, your choice must be entirely made by putting the results you expect in the equation. It will depend on the power you are looking for, the type of material you want to weld, the use you are going to make of it, or the power of your electric current.

The Type and Thickness of Material

Dedicated for welding thin tubes, steel or stainless steel tubes, and thin steel or carbon steel sheets, the TIG welding station can only be a good tool. Thanks to this specificity, the MIG welding station allows you to give your work a perfect finish. The finish is finer and its easy use brings more precision to the user.

Portability

Portability is extremely important in these welding machines because it will make the difference between a stationary use and the possibility of being able to move while working. For this reason, many models weigh around 9-10 kg and are equipped with an integrated shoulder strap. However, the lower weight can reduce robustness, so choose carefully based on the jobs you plan to do.

Ease of Use

Ease of use is essential for both novice and experienced welding professionals. If you are a beginner, you will undoubtedly have to focus on a welding machine with a few clear and efficient controls, to learn how to weld without complicating your life too much. The possibility of welding with an MMA electrode will also make your life easier, with materials such as aluminum and various alloys.

If, on the other hand, you are an expert in this sector, you should look at models that are rich in features, but which do not unnecessarily complicate your work experience. The complexity of the controls must increase your job opportunities and not hinder them.

Accessories

Some of these welders also have accessories already included in the package, such as carrying bags, electrode holder cables, pliers, and much more. However, these are usually more suitable for those who are beginners, and soon you will have to rely on additional accessories of superior quality.

The Type of Power Supply

As the variety of models and brands is so vast when it comes to welding stations, the power of these machines can also vary according to the user’s needs. Models operating with 220 V single-phase current have the advantage and ability to provide continuous and constant efficiency. On the other hand, with a three-phase 380 V current that can deliver 400 to 600 A, this advantage is not available.

The Magnitude of Electric Current (Amperes)

The magnitude of the current therefore plays a very important role in carrying out the welding work. For a weld diameter of 4.0 mm, a 200 A substation is required. Above this, i.e. from a diameter of 5.0 mm, a three-phase power supply is required. For a 6.3 mm electrode, up to 400A is required for welding. This selection criterion is absolute to be taken into account in order not to make a mistake in your choice.

The current supplied at the output of the welding station is distinguished by additional parameters such as the voltage in volts at no load and the type of alternating or direct current.

The welding current increases according to the work carried out during welding and depends on the size of the electrode. In the case of a TIG welding station, 150 Amperes is the minimum required current. The no-load voltage should be 70 or 80 Volts for special TIG electrodes.

Protection of the Equipment

Since tig welders work at high temperatures and with high electrical power, the equipment must have self-protection systems that guarantee its proper functioning and complete safety during use. In the case of heat, and given that the welders have a complex electronic system to control it, the equipment must have an adequate cooling system.

This system is usually based on fans that remove the heat by releasing fresh air from the environment into the equipment, thus preventing it from heating up. Concerning electrical systems, fuse protection systems are often used to absorb possible voltage peaks, thus preventing them from affecting the machine and damaging it.

You must eliminate from your tig welder comparison any model that does not include these protection elements since they will surely have a short useful life and poor operation.

Technology of Torches

Since TIG technology does not use standard electrodes, as in inverter welding, what is important is the torches used during the welding process. These torches incorporate the gas that allows the welding to be done, varying according to the size of the area to be welded and the metals used. Therefore, it is important that the torch is made of the material we need for the welding we plan to use and that it is of adequate size.

At this point, it is convenient to look for sets that offer torches of different sizes depending on the work that you usually do. Don’t forget to look for some basic elements such as the pencil torch, for small welding jobs or the large size torches for surface welding on large surfaces. The change of torch should always be quick, to make the work easier, and models that do not have this function should be rejected unless you do not plan to use the welder for any other purpose than that for which the torch is used.

Duty Cycle

The duty cycle of some devices is limited because electrodes and power supply unit heat up. To prevent damage to your welding equipment, there is so-called overheating protection and a control lamp glows if the equipment gets too hot. Before you buy a TIG welder, you should inform yourself about the maximum duty cycle. The cool-down period is also very important if you do not want to wait so long to continue the welding process.

Cooling

Some TIG welders have built-in cooling, which ensures that you can switch on for longer periods. Often fan-like blowers in the housing provide sufficient cooling. In some units, the cooling is done with inert gas.

Frequency of Use

This is an important aspect because if we are going to use the TIG welding machine for domestic use, we can acquire economic equipment and that does not contain a lot of amperages, even so, we will obtain good results, if on the contrary, we give it a professional use we must obtain a much more powerful model with greater amperage and that offers a greater output.

Size and Weight

One important aspect is that you must know what you are going to use your TIG welding machine for, whether it is for domestic or professional use because depending on the amount of material you are going to move, you must opt for a lighter and more compact model, remember that the bigger it is, the heavier it will be.

Additional Questions That Affect Your Selection

What Can Be Welded With a TIG welding Machine?

TIG welding machines or inert-gas welding machines are suitable for welding many materials. These include austenitic CrNi steels, copper and copper alloys as well as nickel-chrome alloys and nickel-copper alloys.

Titanium and titanium alloys can also be welded with a gas shielded arc welding machine. With an AC/DC TIG welding device, the welding of aluminum is also possible.

What is the Difference Between Welding Equipment, Cutting, and Welding Torches?

Gas is an indispensable medium for all three devices. The big difference is the use of gas. In gas-shielded welding equipment, the gas used does not burn, but envelops the molten metal and shields it from the oxygen contained in the ambient air. However, you can avoid using gas in TIG welding but the quality of the weld would be inferior.

With cutting torches the gas is burned. The properties of the gas and the design of the torch ensure a particularly hot flame. This is also able to cut through thicker metals. In contrast to welding equipment, cutting torches are therefore not used for joining but for cutting metals.

Welding torches, on the other hand, join workpieces. This is done by melting welding rods with which the workpieces are joined together. This requires a hot flame, which is produced by burning special gases.
