10 Best TIG Welders On The Market In 2020 Including Buying Guide

TIG welders are great if you require an electric welder. They have the ability to weld various types of metals and are less risky than gas welders. However, just like any other welding product, you have to deliberate on multiple aspects before buying one, including their power consumption, duty cycle, and more. You can read my ultimate TIG welder buying guide for the most important considerations.

Today, I will be sharing with you the best TIG welding machines available in the market for the current year. So, if it is the best TIG welder you seek then sure to read this article until the end for helpful advice and some great options:

Best TIG Welders – Buyer’s Guide

TIG welder can be the perfect choice for you if you are looking for an electric welder. However, you cannot buy the best TIG welder based solely on the price. You must purchase something that matches your needs and preferences.

You should be mindful of the fact that TIG welders can consume high levels of power. Furthermore, there are other factors you should look at when searching for the right TIG welder. Following are my top considerations that you should remember during your search:

1. TIG Welders and MIG Welders Differences

If you a new welder or are inexperienced about buying welders, then it is easy to confuse TIG and MIG welders.

Understandably, it can be easy for the untrained eye to mix up the two since they use electrical parts for shaping and cutting metal. Additionally, both TIG and MIG minimize the risk of corrosion and rust.

Following are some of the most apparent differences between the two types:

Work Process

MIG stands for “Metal Inert Gas”, these welders operate when metal is fed metal into a weld. The wire serves as a consumable filler material that attaches the metals, which is referred to as Gas Metal Arc Welding (GMAW.)

Whereas TIG stands for “Tungsten Inert Gas”. TIG welders have non-consumable electrodes that work on electric current for welding two metals. The TIG welders don’t necessarily use filler metals. The TIG welding process is referred to as Gas Tungsten Arc Welding.

Working With Thick Metals

The MIG Welders require consumable metal fillers for welding, which cuts down the time needed to weld thicker metals. On the contrary, the lack of filler material in TIG welders limits their heat production, which means they need more time to weld thick metals. Therefore, TIG welders are more suitable for thinner metals, and MIG is ideal for thicker ones.

Ease of Use

Comparatively, many welders find MIG welder to be much easier to use, which makes them more suitable for beginners and inexperienced welders. Welders need more skill and higher control over the equipment for TIG welding.

To use TIG welders to their highest potential, a welder must have control over the process including time, pressure, and the electric current. It is now common for welders to use welder machines alongside computer-controlled machines for better results.

Irrespective of the type of machine you use, choosing the right one for your needs and setting it to the correct settings is critical for ensuring that they are functioning optimally and reducing mistakes.

2. Duty Cycle

The welder’s ability to work continuously is signified by its duty cycle or DC. This value is usually presented on the welder as a ratio or percentage of the maximum active time.

Welders with a high DC ratio are suitable for commercial and dense metal operations. Such machines take a shorter time to cool down, which increases your ability to work continuously. High-quality TIG welders made for commercial use are usually more expensive and can operate for up to 6 minutes at a time with a 60% duty cycle.

However, if you need a TIG welder for less intensive tasks, home projects, or hobbies, you can go for a low duty cycle welder. Machines with a DC of 20% are cheaper and more suitable for lighter tasks and soft metals.

You should be mindful that a power surge can have a negative impact on DC because it can overwork the cooling mechanism.

3. Input Power

Along with the duty cycle of the welder, you will also have to consider the input power or AMP rating because it will give you an idea of the type of tasks the machine is capable of. For commercial use and heavy-duty operations, you will need a high input power welder.

Nearly all of the welder available on the market will have automatic adjust-ability between DC and AC. However, you should know the power phases you require to avoid any issue. Remember that all TIG welders work at a specific range.

Consider the gauge and thickness of the metals you will be working with because that will help you determine the input power you will require for your machine. Aluminum and steel are commonly used in TIG welding.

To get the best value for your money, my suggestion is that you buy a high input machine that will allow you to work with all gauges and thickness of metal. A direct current device is suitable for hard metals. With a low input power alternate current machine, you will be able to work with metals with a low density only such as magnesium.

4. Automation And Digitization

Digitization and automation can increase the convenience and ease of performing your welding task. Highly practical features like automatic shutdown and high-temperature balance and shutdown will make your job less stressful.

Such features will decrease the damage to your machine and lower the amount of maintenance. These features are great for inexperienced welders. However, they might not be useful for experienced welders.

Digitized features allow you to stick to the recommended maximum power output, voltage, etc., so you will not have to worry about the machine overheating.

5. Weight

Welders due to their easy portability, size, and the weight mostly prefer light machines; these should also be an essential consideration for you when choosing the best TIG welder.

If you’re going to work at one place and will bring projects to your bench, then you can select a heavyweight machine. However, if you need to go to the projects and easy portability is important, then lightweight TIC welders are necessary.

Most of the weight of a TIC welder is focused on the transformer. Therefore, learn about the weight of the transformer when considering a welder. The durability of the handles is another critical factor. Look for a machine that won’t break easily with repeated lifting.

Frequently Asked Questions (FAQs)

---

1. TIG vs MIG welding, Which is better than the other?

MIG welders are more commonly used because the parts are readily available and they are best suited for thicket sheets of metal and quick welding tasks. Whereas, TIG welders can do wonders and work neatly while joining smaller pieces of metals. When it comes to exceptional quality welding, I highly recommend you to invest in a TIG welder.

2. Is TIG and MIG welding procedure the same?

If your compare TIG and MIG welding, without a single doubt, TIG produces superior quality results, but TIG welding is slower and has a great learning curve. On the other hand, MIG welding is faster and easier to learn, but it is not suitable for thin materials. TIG welding also allows a cleaner finish than MIG welding as TIG welding doesn’t splatter.

3. Can I use my welder for welding aluminum?

Aluminum is a more sensitive material than steel. Hence, you can use your welder to weld aluminum only if your welder supports both DC/AC on 110V/220V voltage.

4. Are all welders compatible with both stick and TIG welding?

Most welders are usually compatible with both TIG and stick welding. However, not all welders provide the full package; hence, you may have to buy the stick separately.

5. What are the top benefits of TIG welding?

Following are the top 3 benefits of TIG Welding:

• A TIG welder can efficiently weld a wide variety of metals.
• TIG welds are cleaner and more durable than other welds.
• You do not have to worry about sparks, spatter, slag, smoke, and fumes with TIG welding.

6. Which gas works best for TIG welding?

Argon is commonly used and recommended for TIG welding. Alternatively, you can also use Helium for higher speed and greater penetration.

Final Verdict

There you have it! Now you have my simplified guide to buying the best TIG welder, and a list of 10 best TIG welders that you can trust for both professional and home use.

Although there is a massive range of welders available in the market. However, the 202 Lotos TIG200ACDC TIG Welder will remain to be my top favorite and highly recommended best TIG welder of all time!
