The Top 10 Best Tig Welder for Aluminum

(Last Updated On: September 18, 2018 )

Aluminum is one of the most difficult metals to weld. Aluminum alloys are more challenging to weld than steel alloys as they have a lower melting point and higher conductivity. This means that you need the best TIG welder for aluminum to get it to the right temperature and maintain it, as aluminum can hold the heat for long. 

Tungsten Inert Gas which is widely known as TIG welding is the best way to weld aluminum. Whether you are working in the automotive industry, pipefitting or simply doing a DIY project, the best cheap TIG welder can help you finish your job in the best quality. If you are not that experienced with welders or looking for a good upgrade to add to your workstation, then this article is for you. You will find relevant information that will enable you to buy a great TIG welder for aluminum.

Why Do You Need the Best Tig Welder for Aluminum?

A good TIG welder for aluminum will provide the needed heat, precision and cooling you need for the job. Since working with aluminum is one of the most difficult tasks, you need to make sure that you’ve got the best TIG welder for aluminum ready for the job.

TIG welding requires a shielding gas. Argon is usually used for the job. You also need a tungsten non-consumable electrode and a surface that will enable you to remove the oxide buildup. You need to be able to control the heat as you will need more heat at the beginning of the welding process and less heat towards the end. TIG welding looks better and is better sealed than MIG welding, especially if you know how to do it right using the best TIG welder for aluminum.

Some welders are not necessarily TIG welders but have the needed accessories so you can use them to weld aluminum. These are also great because they give you more options to work with different materials for various jobs.

​How to Choose the Best Tig Welder for Aluminum?

Choosing the best TIG welder for aluminum is a bit challenging, especially if you are not that experienced with welding. There are tens of TIG welders available for sale and the difference in the price and capabilities is obvious. Finding the most appropriate and reliable welder is difficult for both amateurs and professionals. Nevertheless, there are a few features that can help you pick the most suitable product for your upcoming welding project.

Amperage Range:

This is the first feature to think about while looking for a TIG welder. This determines the materials, metals, and alloys that you will be able to weld using your machine. 

It is a good idea to consider buying a machine with a wide amperage range. This gives you more options and freedom while working because you can weld different metals. It is the perfect choice for people who are working with thin and thick materials. If a versatile machine is too expensive you will have to buy something that suits the materials you usually work with.

Performance at Low Amperage:

You need to make sure that your TIG welder is flexible and stable at low amperage. This guarantees the quality of your work at low power output. This is one of the best features to use while working with thin materials as it keeps your welding clean.

Stability is one thing that you can’t ignore while working with thin metals. If your TIG welder is not stable, it won’t be safe to use and can damage the material you are working with. This can cost you more than money, as it might ruin your whole welding project. While working with aluminum, you need to make sure that your welder is stable as you are gradually reducing the power output for the best welding results. 

Ac/dc Option:

If you are planning to work with something other than steel, then your welder should have the AC/DC option. This is the only way you could weld self-oxidizing metals like aluminum. A machine that can do both is going to be the perfect option especially if you tend to work with various metals and alloys. 

Alternative current or AC alternates between positive and negative. The positive cycle cleans the metal while the negative cycle performs the welding. This means that you need a control to set the length of each cycle. This control could be manual or automatic to guarantee that your welding jobs are finished in the best quality.

Heat Control:

While working with thin metals, you need to make sure that you can control the heat. Working at low temperatures guarantees that your arc will be stable while working with more challenging metals and alloys. 

Duty Cycle:

This represents the amount of time your TIG welder is able to work under maximum output without being left to cool down. A welder that has high duty cycle will allow you to finish your welding job faster because you don’t have to leave your machine to cool off. This also guarantees that your machine will last for long because it is very well made.

A higher duty cycle is suitable for professionals and people who take TIG welding seriously. If you are an amateur or a hobbyist, you don’t have to spend that extra money on a high duty cycle.

Weight and Portability:

TIG welders come in all shapes and sizes. A lightweight machine is portable and very easy to transfer and store. This is a great option if you wish to use your TIG in the outdoors or away from your workspace. However, if you always tend to work in one place to finish your repair work or welding jobs, the weight shouldn’t be an issue.

Easy to Adjust:

While welding aluminum and other thin metals, you need to make sure that you are able to control the heat and power easily. This improves the quality of the welding job and guarantees that the arc will stay stable as you leave the welded part to cool off. 

Your TIG welder shouldn’t be very difficult to adjust and control. Make sure that you buy a machine that you can easily set up and use even if you are not that experienced with welding.
