TIG Welding 101 Main TIG Welder Uses​

The TIG welding equipment relies on the tungsten electrode to heat up the metal to be cut. Due to its applicability, this machine is mostly preferred by professional welders and is in high demand.

It can be used to cut and process different metals like copper, magnesium, steel, gold, brass, and aluminum.

For metals with heavy thickness, welders use inert gasses such as argon in order to protect it from contamination.

Below are some of the most common uses of a TIG welder:


The automotive industry relies on TIG welders to manufacture accessories for cars. Using a TIG welder helps to minimize corrosion over time.

Car manufacturers rely on TIG Welders in preventing rust and cutting the metals needed to manufacture different types of vehicles.


When it comes to repairing different types of metals, a TIG welder can be useful. Whether it’s an old-fashioned car, a wagon, children’s toys, aluminum tools, and more, this machine will help a lot.


The aircraft and spacecraft industries have long been relying on TIG welders to produce parts.

Both space and commercial planes need complex parts to be produced and these parts are made of metals that have to be designed and cut precisely.

This is where they can benefit from the use of TIG welders.


Artists who want to express their creativity by sculpting metals and producing different kinds of sculptures can benefit from TIG welders as well.

This machine can be used for various industrial fixtures and in making metal sculptures.

Things to Look for When Shopping for the Best TIG welder

Keep in mind that TIG welders consume a lot of power during operation. Whether you’re an amateur or expert in welding, you should choose something based on your needs and preferences.

Here are some of the most important things that you need to take into consideration when looking for the best TIG welder to buy:

Duty Cycle

Duty cycle is the welder’s ability to continuously work on the machine. This is often expressed as a ratio or percentage of the overall active time.

When using the machine for dense metal operations and commercial use, you might as well go for high DC machines. This decreases the amount of time you need to spend in having to wait for the welder machine to cool down.

For lighter welding tasks, such as home DIY projects, it’s best to go for TIG welders with a low-duty cycle. This machine should be able to work for this purpose without any issues.
A power surge could decrease DC. This is because the power input could increase the possibility of overworking the cooling system.

Cheaper models of TIG welders usually come with 20% DC. This is what makes them better suited for lighter tasks and when working with soft metals.

On the other hand, TIG welders that are of high quality and are generally more expensive are designed to work for more than 6 minutes through a duty cycle of 60%.

Input Power

The input power will depend on the type of tasks that your device will perform. If you plan on using it for heavy-duty operations, choose a welder with a high input power.

Most of TIG welders are equipped with automatic DC and AC adjustability features. TIG welders operate at a specific range. You should be aware of the power phases that the machine is capable of working without any issues.

When deciding on the input power of a machine, consider the kind of material that you’ll be welding on.

Aluminum and steel are the two most common materials that are being processed in TIG welders and these materials have varying gauges and thicknesses.

If you want something that can give you the best value for your money, go for high input machines capable of processing thick metals. Direct currents are generally more suitable for hard materials, such as stainless steel.

TIG welders that have low input power are more suitable for processing low-density metals like magnesium. But if your material isn’t dense, then AC current is good enough for you.

Racing cars are made mostly of steel, which requires the high input machines.

Digitization and Automation

Digitization and automation can help make your welding tasks a lot easier. Some of these machines come with automatic high-temperature balance and shutdown.

These features are necessary for the maintenance of your welding machine. But if you’re an experienced welder, you may find it more convenient to operate the manual versions.

Digitized and automated welder machines are more suitable for amateurs and new users.

Machines that come with digitalization make it easier to adhere to the manufacturer’s regulations in terms of power output, voltage, etc.


Most welders prefer working with light machines. When it comes to portability, weight and size are important factors to consider.

If you’re going to operate the machine in a permanent position, you might as well go for a heavyweight TIG welder. But if you’re someone who prefers to work in different locations, then the lightweight machines will work best for you.

It’s the transformer that’s the heaviest component of a welder. Thus, if the transformer is heavy, you can expect the machine to be heavy as well.

Some machines, despite being lightweight, are still difficult to carry and have unreliable handles that could get broken easily with regular lifting.

Differences Between TIG Welders and MIG Welders

Most welders, especially amateurs, are often confused between TIG and MIG welders.

This is pretty acceptable since both of these welding machines rely on electrical parts in cutting and shaping metals. In addition, both machines are known for preventing rusting and corrosion among metals.

Yet, these two machines differ from each other through the following:

Work Process

MIG refers to Metal Inert Gas and it works by feeding metal into a weld. The wire will serve as the consumable filler material that will be responsible for attaching two metals together.

This process is known as the GMAW or Gas Metal Arc Welding.

On the other hand, the TIG welder or the Tungsten Inert Gas relies on non-consumable electrodes to operate an electric current through the two metals being welded. The TIG welder may or may not necessarily use filler metals.

Such a process is known as the Gas Tungsten Arc Welding.

How They Deal with Thick Metals

The MIG Welder relies on filler consumable metals when making welds. Thus, it only requires a short amount of time to weld thicker metals compared to TIG welders. Since TIG welders don’t use any filler material, they won’t be able to produce enough heat to bond two metals and will, therefore, take more time.

Thus, TIG welders are more suitable for thinner metals and not much for thicker ones.

Ease of Use

MIG is much easier to use, which is why it’s highly recommended for amateur welders. TIG welding, on the other hand, requires strict control over the machine.

The welder must have control over the time, processing, pressure, as well as the electric current. These welder machines are often used alongside a computer-controlled machine.

Both MIG and TIG machines have to be set in the right settings for them to function well and minimize any mistakes along the way.


How to use a TIG welder?

You can use TIG welders in various ways, depending on the machine’s voltage, amperage, and the type of metal being processed.

Some models of TIG welders are able to automatically detect the voltage being used and will adjust accordingly.

When buying these machines, you’ll get a user manual that will explain how to set up and use the machine so you better read that first.

Can the TIG welder be used for aluminum?

Aluminum requires using Alternative Current due to the metal’s sensitivity.

As such, if you plan on working with aluminum material, make sure the welder machine that you’ll use supports AC.

What is duty cycle and how will it affect welding?

Duty cycle refers to the percentage of time that the machine can work in 10 minutes. This is usually presented in percentage or rations.

DC is what determines your overall output when continuously working with the machine.

Will the TIG welder come with both Stick and TIG welding options?

Most of the TIG Welders of today give you a choice of TIG or stick welding while others don’t offer the full package even if they’re compatible.

For this option, you just basically need to purchase the stick separately.
