Best Tig Welder To Look For In 2020 – Reviews & Buyer’s Guide
Also known as Gas Tungsten Arc Welding, the Tungsten Inert Gas (TIG) welding is a process of arc welding that uses a non-consumable form of the tungsten electrode to weld together two surfaces.
What is a TIG Welder and what is it used for?
The TIG welding method gained popularity in the 1940s because of its ability to combine aluminum and magnesium. In order to protect the weldpool, instead of using a slag, an inert gas shield was used. This method became an overnight success and a popular replacement for manual and gas metal arc welding. TIG also became one of the reasons for the acceptance of aluminum in structural and high-quality welding projects. The TIG process uses a tungsten electrode (non-consumable) in order to create the weld. The inert shielding gas protects the electrode and the weld area from atmospheric contamination and oxidation.
The TIG method can be used to weld non-ferrous metals like copper, aluminum, and magnesium alloys and stainless steel. Using this method, the users will have better control over their weld, resulting in high-quality and stronger welds. The TIG method is, however, much more complex and cannot be mastered very easily. Moreover, it is slower than other welding options.
How does a TIG welder work?
When compared to other welding methods, this is a little difficult because the welder has to have good coordination. The method requires the use of both the hands because, for most projects, the operators will have to use one hand to feed the metal while the welding torch is manipulated by the other hand. A short arc length should be maintained while making sure there is no contact between the workpiece and the electrode.
An electric spark is provided by the high-frequency generator and this is needed to strike the welding arc. When this is done, the torch is moved in little circles to produce a welding pool, and the size of the welding pool is based on the amount of current given and the electrode size.
A constant separation between the workpiece and the electrode is maintained while the torch is moved back and tilted slightly. Finally, to the weld pool’s front end, the filler metal is manually added.

How to Choose the Best TIG Welder
1. Input Type
Each TIG welder has a designated input standard. On a TIG welder, the different electrical inlet types are DC and AC. For hard metals like copper, stainless steel, and steel, DC welds are better and for soft metal, with self-oxidizing properties (e.g. magnesium and aluminum) AC would be more suitable. If you are unsure of which input source is present at your end, then you could get a welder that supports both.
2. Amp Rating
It is best to choose a model that gives the widest range of amperage. Your welding works will be limited when your welder has a lesser amperage range. A welder with a 5-230 amp range will be flexible enough for thin materials.
3. Thickness of Metal
No matter what process you choose, the thicker the material you are welding, the higher the requirement of current. Therefore, you must choose a welder that can provide enough current you need for that material.
4. Power Input
When the machine’s voltage rating increases, the capacity of the machine will also increase. This means that you can weld a lot of metals with a high voltage device. But the voltage at the source should be equal to or greater than the TIG welder’s voltage rating to power the device properly.
5. Ignition Type
When starting the welding process, ignition is required. Different TIG welders require different types of ignition methods. The most common ignition types are lift start and high-frequency start.
6. Adjustment Settings
Adjustment settings on TIG welders should include control over functions like current ampere, current frequency, pulse time, etc. Based on your requirements, you can manage these settings.
7. Duty Cycle
This shows how much uninterrupted work a machine can do in a given time interval, at its highest current. When this threshold is reached, the equipment must be left aside in order to cool down. Duty Cycles are usually represented in percentage values.
Larger TIG welders weigh around 100 pounds or more while smaller ones weigh only around 50 pounds. Smaller ones will provide enough power for smaller jobs and are a lot more versatile.
9. Digital Control
Most welders have digital controls which makes them safe to operate and easy to use. The screen will show information like power, voltage, and many others. The information will make the task more accurate and perfect.
10. High Quality Arc
Arc stability issues are seen in the cheaper models of TIG welders and unsteady arcs could become the reasons for problems with the look of your weld. Therefore, welders with high-quality arcs are important.
11. Pulsed Welding
TIG pulsing is used for working on thin metals, difficult joints, or stainless steel where extreme heat can cause it to rust. But pulse rating is high in TIG welders, making the weld stronger. The pulsing rate can help welders have a cleaner weld by allowing them to travel faster over the metal.
12. Foot Pedal
A reliable foot pedal is very important in TIG welding. A pedal will allow you to control the heat used, ensuring the weld puddle does not become very large. Make sure the TIG machine’s foot pedals are responsive and have a natural angle.
This is important if you transport the TIG welder to different places. Usually smaller welders are easy to move around.
14. High-Frequency Settings
High-frequency settings would make it easy to control the arcs when compared to a TIG welder with low settings.
15. Plasma Cutter and Stick Welding
If you want greater versatility and some extra features, then consider purchasing a TIG welder with both plasma cutting and stick welding capabilities. When plasma cutting and stick welding is available, you can save time on projects that require metal cutting and you can do any work that comes your way.
16. Air-Cooler Torch Vs Water Cooler Torch
During a high power output, the torch will become warmer but most people do not see it as a problem. A water-cooled torch can do a finer work in tough spots because it has a smaller head. Many welders using water-cooled torches really appreciate not experiencing the intense heat on certain jobs, where the air-cooled torch would not be enough.
A TIG welder can be found in many price ranges depending on the equipment, packages, brands, and features. If you are a hobbyist welder, then a device below $500 dollars would be enough while for professional welders, a welder ranging around $1000 would help. However, if most of your work is on titanium metals, more expensive models would be required.
Most TIG welders have a warranty of 2-5 years and the longer the warranty duration on the product, the more reliable your device would be.
Benefits of Using a TIG Welder
TIG welding produces precise, clean welds on any metal. A few other benefits include:
• Filler metal is added by hand when required
• It uses a non-consumable tungsten
• Produces clean, high-quality welds
• Shielding gas protects the tungsten and weld
• It welds more metals when compared to other processes
Drawbacks of Using a TIG Welder
Some few drawbacks of a TIG welder are:
• TIG welder is slower than any other welding machines
• Filler deposition rate is lower
• Initial cost is high
Common Mistakes When Operating a TIG Machine
Some common technical mistakes when operating a TIG machine are:
• Poor gas coverage will lead to contamination- This usually occurs when shielding gas is switched off.
• Choosing the wrong current- depending on the type of electrode and metal, use AC and DC.
• Weld grittiness- this is usually caused when welding at a very high temperature
• Not cleaning materials- make sure your materials are cleaned before you begin welding
• Using high amperage on aluminum- this creates a broader outline and can burn through.
