When Should You Use A Tig Welder

You should use tig welder to weld sheet aluminum thinner than 1/2″. You can weld thicker aluminum also with a Tig welder. Though many people prefer mig welder with a spool gun to weld thicker aluminum as it is easy to use mig welder. But mig welding is not as clean and precise as tig welding can provide.

In addition, tig welder provides an option to control input power using a foot paddle. You can easily adjust the power with the paddle which is missing in mig welder.

Furthermore, automotive welding especially repairing motorbike has made tig welder a popular technique for its perfect finish and seamless welding.

That’s why when you are opting to weld an aluminum, you may go for tig welder for better result.

Can Any TIG Machine Weld Aluminum?

Multiple TIG Welders can weld aluminum without any complaints. Often, experienced welders recommend using a TIG welder for thinner and lighter gauge aluminum.

A TIG welder produces cleaner & better quality welds than other available welding methods. In addition, when you run a TIG welder in AC current mode to complete an aluminum welding project, it can produce perfect result.

You need to consider some requirements to weld aluminum with tig machine. If you can configure the settings then you will be able to weld aluminum with any tig welders.

For example: You will need to adjust the heat to successfully tig weld aluminum. Adjustment would provide you with complete control over machine’s filler rod.

Lets see the chart that contains requirements for tig welding, tig rods diameter & amperage bellow-

Base Aluminum ThicknessTungsten DiameterAmperage

What Is The Best Technique To Weld Aluminum?

There are indeed several welding techniques available to weld aluminum material. These include MIG Welding, ARC Welding, TIG Welding, Resistance Welding, Electron Beam Welding Etc.

In most of the cases, the TIG welding technique is highly recommended and worth considering for completing Aluminum Welding tasks.

This method is best to use for thin Gauge aluminum welding. Moreover, it is also recommended by most welders for steel and thick aluminum welding.

The TIG welding method is chosen to weld aluminum because it significantly controls the heat and produces finer welding results.

You can use the foot paddle of a TIG welder and adjust the heat.

However, a MIG welder is also ideal for performing heavy or thicker aluminum welding duties.

But there will be a downside as welding might not provide the cleanest results. Therefore, a TIG welder is highly suggested for Aluminum welding.

Aluminum TIG Welder Buying Guide

Get to know about some of the best buying tips that would benefit getting a value-for-money TIG welder for Aluminum welding. These tips are described as follows.

Type Of Projects

It’s good to decide which types of welding projects you will use your TIG welder before you spend any money. Are you considering using it as a hobby or learning welding yourself?

Or do you need a welder to perform commercial welding jobs? That’s all on you. This way, you will choose between a heavy-duty and mild-duty TIG welder.

Consider investing in a low-duty welder if you don’t need to perform many welding jobs in a month.

Base Metal

Getting a TIG welder will also depend on the type of metals you want to use it for. Different ranges of metals include carbon Steel, Mild Gauge Aluminum, Heavy Gauge Aluminum, Stainless Steel, Mild Steel, and other metals.

Including that, you’ll decide on that welder’s capacity to weld a specific metal.

So, choose wisely, as some TIG welders may weld aluminum, and some not. Also, it’s essential to consider whether you are welding heavy-duty or soft-gauge metals.

Your Budget For The Project

Sometimes, you cannot spend huge money on a TIG welding machine. It’s all because you have already invested in buying other required stuff.

Therefore, decide how much money you will spend on a TIG welder. Usually, a TIG welder between $400 to $650 bucks will perform your job nicely.

Type Of Input

TIG welders can work on AC and DC volts. But for aluminum welding, you only need AC voltage.

Therefore, you can even buy a machine that’s only offering AC voltage and does not have dual voltage settings. It would be a great selection while saving more money.

Check The Duty Cycle Rating

The duty cycle defines the time you can use a welder before it starts overheating. In this way, you must choose the one with 10 minutes of duty cycle.

A smaller measure is that if there is a 30% duty cycle rating for a TIG welder while working at 200 amperes, that machine will be efficient for almost 3 minutes.

And it will require 7 minutes to cool down before you use it again.

Gas Cylinders

Ensure that your TIG welder can connect argon and other gas cylinders. Because  without these gases, TIG welding aluminum or any other metal is impossible.


The next thing you need to check on a TIG welder for aluminum is the warranty. Usually, an outstanding TIG welder will give you up to 3 years of remarkable warranty.

Digital Control

A TIG welder with digital controls is more straightforward than a TIG welder with Manual Controls. Therefore, if you have come this far, try finding this feature in a TIG welder.

Type of Ignition

A TIG welder either comes with an Arc Lift or HF ignition. Therefore, you need to determine which one will suit your job best.

The Arc lift ignition starts when you touch the metal with the Torch. At the same time, the HF ignition starts when you press the torch trigger.

That’s the fundamental difference between these two.

Last Words

Haven’t been the entire article exciting and worth reading? Did it help you get your desired TIG welder?

Well, we hope that you have made a purchase. But if you didn’t or have any queries in your mind, you are always welcome to ask.


Do You Need Gas For Tig Welding Aluminum?

For TIG welding Aluminum, you need Inert Gases. Without these gases, you won’t be able to perform TIG welding.

Is TIG Welding Aluminum Harder Than Welding Steel?

Only  a matter of care. Like, in welding Aluminum, you have to be more careful than welding steel. But most individuals move to aluminum welding after learning steel welding.

Why Is TIG Better Than MIG For Aluminum?

TIG  welding gives more precise, accurate, and clearer finishing, which is impossible with MIG welding aluminum.

What Tungsten Rod For Aluminum?

You need Zirconated Tungsten rod 7019 or 7018 to perform TIG welding aluminum duties.

How Many Amps Does It Take To TIG Weld Aluminum?

Here, we apply the rule of thumb that states using 1amp of current for every 0.001 material thickness. For a material of 1/8 inches, you will need approximately  125 amperage current to complete the process nicely and more profoundly.

    This is James Smith, a Hobbyist welder, welding since my 15th birthday. My father was a professional welding mechanic at a garage and used to take me to garage. My love for welding started then and I learnt basics from my father. At my 15th, my father gifted me a stick welder and my journey to become a welder began. Gradually I accustomed to welding and mastered at tig welding.
