Guide To The Best Tig Welder For Aluminum (2023 Update)

TIG welders are an alternative to the Advanced High Frequency (HF) metal-inert gas welding process. TIG rests for a Tungsten Inert Gas Welding process. As the name implies, it uses metal welding elements, tungsten electrodes, and inert gases to create a controlled weld buildup. The tool is therefore known as a Tungsten-Inert Gas welder. You are in the right place if you are looking for the best budget, medium-scale, or even a professional TIG welder. After careful research and study, we have compiled a list of aluminum TIG welders to meet the requirements of both hobbyists who want to become medium-level fabricators and professionals. Look at our aluminum TIG welder reviews and see which one could be your next TIG welder.

Here are the best tig welder for aluminum on the market.

Electrode And The Workpiece

TIG (Tungsten-Inert-Gas) – Inert gas welding with inert / inactive gases such as Argon 4.6 (99.996%). An arc is created in an argon bell between the tungsten electrode and the workpiece. This melts the material and any filler material that is supplied. A weld seam is created. MMA / Stick electrode welding– is a universal welding process. No protective gas is needed and can therefore be used flexibly anywhere.


The footswitch allows you to operate the tool manually without having to free a hand to hunt for your off switch, saving time in finding the switch and improving work efficiency. Tap with your feet when you need to stop the tool. Improve safety and prevent injuries in an emergency.

What To Consider The Best Tig Welder For Aluminum When Choosing Before Purchasing


Welders with inverter welders or multiprocess welding equipment that don’t use TIG as their principal welding process are more likely to use scratch start as their basic process. However, it is still used for welders built for Stick welding or MMA. Therefore, it is not considered obsolete. To start the arc, lightly scratch the TIG tungsten electrode and remove it, so it doesn’t stick to the workpiece. To prevent the arc from going out, don’t raise it too high.

Various Obligations

The duty cycle is the time you can weld before your machine overheats. The typical cycle time is ten minutes. You can weld for three minutes at a time and then let it cool for seven minutes using a TIG welder with a 30 percent duty cycle at 200 amps.

Consider your needs and thoroughly comprehend this feature before making a decision. Multi-process machines frequently excel in a primary welding process before moving on to a secondary process with a lower level of complexity. Secondary processes like TIG, MIG, or a mix of the two can be given priority.


Portability is essential for individuals who intend to use it in numerous locations (like home and workshops). The weight of the apparatus is crucial in this equation.


The warranty is still another crucial factor. You should get more information from the provider if you have doubts about the guarantee duration or stipulations.


After the tungsten electrode makes contact with the workpiece, a pull upward and away initiates an arc. The starting current is modest so that the tungsten won’t stick to the workpiece. Due to the low current, the sharpened point won’t be affected. As soon as you gently lift the electrode away, the machine will detect that the contact has been broken and gradually start to provide a full welding current.

Lift start is easier to control and more user-friendly than the scratch start. However, the electrical process needs to be accurately adjusted for the machine to operate efficiently. If the initial current is not kept to a minimum, the tungsten electrode will adhere to the workpiece.


The simplest way to start the arc is with a high-frequency start. You should notice if the machine has a high-frequency start and is within your budget. Place the tungsten electrode close to the workpiece and pull the torch trigger to start the arc. Simple as that.

Frequently Asked Question

What TIG welder do I need for Aluminium?

To weld the aluminum thicknesses you’re dealing with, you’ll need AC/DC equipment with enough power. They have the properties of good TIG machines, like R-AC/DC Tech’s TIG161 and 170EXT.

Is DC TIG good for aluminum?

Don’t be hesitant to experiment with DC GTAW on aluminum. Just keep in mind that the method is different from AC’s. Before using it on real components, I recommend that you practice first.

How many amps do you need to weld aluminum?

You can use the 1 amp rule to estimate your welding power if the rest of your parameters remain the same. You’ll need about 125 amps if you want to weld metal 1/8-inch thick.

What is the easiest TIG welder to use?

YESWELDER TIG-205DS HF TIG/Stick/Arc TIG Welder with Dual Voltage and Foot Pedal is the best welder for beginners. This little TIG welder is perfect for those who want to learn the basics of TIG welding but don’t want to invest much money.

Is AC or DC better for welding aluminum?

Cleaning the metal completely is a prerequisite before commencing to weld it. The workpiece should be thoroughly cleaned with a wire brush and degreased if necessary to avoid oxidation. Aluminum is better suited to an alternating current (AC) since the heat is less intense.


So the bottom line is that the Lotos MIG 175 welder wins the competition. This product has a great set of features, and it offers more than enough to win over your heart. You should get this if you want a versatile, durable, and easy-to-use model for any household or professional work.
