Best TIG Welders for Aluminum 2022 – Reviews & Top Picks

TIG welding is one of the recent welding techniques which is used for better weld precision. But as a welder, you should choose the right TIG machine for the type of metal you are going to weld. If you are purchasing just for home use, then you may choose a simple DC TIG machine. But you should choose A/C TIG machines to get quality results as these are the Best TIG Welders for Aluminum.

As a beginner, you should first understand the difference between AC and DC TIG welding machines. The current in the DC TIG welder flows in one direction only and sometimes it falls to zero during the process. But in the case of the AC TIG machine, the current flows in a dual direction and never falls to zero until the welding process ends. This dual-direction flow creates more penetration in the metal due to which AC TIG welder is more suitable for aluminum TIG welding.

DC TIG welder works fine for all the metals except aluminum. Therefore, we are reviewing here some best customer-reviewed affordable, and durable quality aluminum TIG welders. You may easily choose from the list for your project.

Buying Guide for Best TIG Welders for Aluminum:

Welding aluminum is different and even more difficult than welding other metals. Further, there are some focus points and features you must investigate as a buyer. Finally, going through this checklist will help you to decide the Best TIG Welders for aluminum.

  1. AC TIG Machine: –

When you are going to weld aluminum, you will need more penetration to avoid oxidation and get clean work. This extra penetration may only be performed by an AC TIG machine due to the constant flow of current. DC TIG welder can weld other metals like steel, stainless steel, copper, etc. but is not suitable for aluminum. So always go with an AC TIG machine for aluminum welding.

  1. Long Duty Cycle: –

The process of aluminum welding needs continuous consistent weld capability in the TIG welder. Because for aluminum welding extra penetration will be required for which consistent weld is required. Moreover, this consistent weld is only possible with the long duty cycle of the TIG welder. Finally, the duty cycle in the range of 40%-60% at high amperage with good arc capability is good for Best TIG Welders for aluminum.

  1. Digital Display Screen: –

There are some welding points that need extra precision and cleaning. Firstly, through the digital display screen in the TIG welders, you will be able to configure the exact settings to achieve better results. Secondly, there are some welders who save up to 10 settings and this feature is highly recommended for welders who require repeat processes.

  1. Portability and Weight: –

Sometimes for outdoor projects portability is the main concern to look for along with the weight of the welding machine. Moreover, carrying a heavy machine of 100 Pounds is more difficult than a lightweight 60 Pounds machine. For example, you will need to prioritize or do a cost-benefit analysis that how much work is outdoor?

  1. Price, Budget & Warranty: –

When there is a budget constraint while purchasing a TIG welder then do not overlook the features requires to perform the welding task. Yes, price is the point of concern, but you should also consider the TIG machine features. As a beginner or hobbyist, you should also check and purchase machines with a long warranty duration.

  1. Air-Cooled, Water-Cooled TIG torches: –

Aluminum welding requires continuous arc penetration in the metal to weld. Moreover, this process creates heat, and TIG torches also get heated. Further, you can use Air-cooled and Water-cooled TIG torches as per the availability of air and water. While using an air-cooled TIG torch you have to stop the work when the torch gets heated but in the case of a water-cooled TIG torch, you will be able to use that without stopping the work. In Conclusion, a water-cooled TIG torch is highly recommended in a warm environment.

  1. Material Thickness Assessment: –

You must check low amperage performance while purchasing a TIG welder for aluminum or any other metals. For example, if you are going to weld thinner gauge material, then it is necessary to start at low amperage to avoid the material burning.

Conclusion: –

We have reviewed some quality TIG Welders for aluminum with strong customer reviews. So you can easily choose your required machine. In addition, we have also provided a buying guide from where you may understand the purpose of some basic features required to weld aluminum.

In our view, for Best TIG Welders for Aluminum with some budget constraint, then AHP AlphaTIG 200X is good to choose with easy-to-understand features. Everlast PowerTIG 200DV is another good option due to its AC/DC diverse features furthermore, it has excellently low arc capability for thinner gauge materials.
