Reviews of the Top TIG Welders for Aluminum

While undergoing testing, we uncovered several noteworthy TIG welders for aluminum. You can find our reviews of these TIG welders down below.

Best Premium - Lincoln Square Wave K5126-1

best overall rating Lincoln Electric Square Wave TIG 200 TIG Welder, K5126-1

Key Specifications

  • ¼-inch Welding Capacity
  • 115V/230V Input Power
  • 25% Duty Cycle @ 200A
  • Pulse Welding Function

If you weld at home or at a place of business, the K5126-1 is one of the most reliable TIG welders you can get your hands on.

It has a max welding capacity of a quarter-inch, even on aluminum, so you’re not losing power when switching to non-ferrous materials.

Like the Lotos above, this TIG welder has dual-voltage capabilities. It works with either 115V or 230V receptacles, some homeowners can also experience the raw power of this Lincoln-made beast.

The pulse function lets you weld out of position without concerns about spatter or unappealing beads. The arc can pulse up to 20 times per second, leaving a smooth bead across the surface of your workpiece.

Check this video out to see what the K5126-1 comes with:

 

Pros

  • Deep penetration
  • Durable construction
  • User-friendly controls
  • Pulse-welding action

Cons

  • Minimum power (10A) may be too high

Made by a trusted company, the Lincoln K5126-1 is one of the best machines with some of the best after-sales service you can find.

Best Budget - Everlast PowerARC 160STH

best overall rating 2021 PowerArc 160STH HF TIG Stick IGBT Inverter 160Amp Welder 110v/220v Dual Voltage

Key Specifications

  • 3/8-inch Welding Capacity
  • 110V/220V Input Power
  • 35% Duty Cycle @ 160A
  • Inverter Technology

As the best budget-friendly TIG welder for aluminum, the Everlast PowerARC 160STH doesn’t come with as many frills as the previous models.

Nonetheless, when it comes to welding aluminum, the PowerARC 160STH doesn’t miss a beat.

This TIG welder can join pieces of aluminum up to 3/8 of an inch in thickness, which is actually thicker than our premium-pick alternative.

It has a lower max output of 160A, so it will require multiple passes to join thicker plates together.

Also, the PowerARC 160STH maintains a 35% duty cycle at max power. For weekend welders, this shouldn’t be a problem, but taking it to professional workshops and hoping for max efficiency is wishful thinking.

Pros

  • Low energy consumption
  • Great aluminum penetration
  • Portable design
  • High-quality Everlast product and services

Cons

  • Could be a little more powerful

We highly recommend the Everlast PowerARC 160STH to those with lighter welding jobs or as an on-the-go TIG welder.

FAQs

Here, we’ll attempt to address the most frequently asked questions about TIG welders for aluminum.

Is it better to MIG or TIG weld aluminum?

The key difference between these welding options is penetration capabilities. MIG welders, in general, are used to join thicker sheets and plates together with a single pass of the gun. A lot of tampering with the voltage, amp, and wire-speed settings are needed to get it right. TIG welding, on the other hand, is made for welding thinner-gauge materials. With the right technique, TIG welding will result in better-looking beads and less spatter.

What is pulse welding?

Pulse welding is exactly what it sounds like—it’s a form of welding where the current is pulsed rather than delivered in a constant stream. Pulse welding results in less spatter, fume reduction, heat reduction, and an overall better-looking bead. When working with aluminum, if your TIG welder has it, utilize the pulse function to avoid melting your workpiece while welding.

AC or DC for welding aluminum?

It’s possible to use either AC or DC settings to weld through aluminum, but using the AC setting is a lot more forgiving. An AC current delivers a positive half-cycle arc that produces cleaner welding action with a reduced risk of melting your workpiece. As for DC polarity, you should use this when working with thicker materials. It produces a smoother but at the cost of higher electrode melt-off.

How much should I invest into a TIG welder?

It ultimately comes down to how much money you’re willing to part with. We’ll be honest; TIG welders can be quite costly, but there are incredibly affordable models and some with ultra-high value for your investment by non-name-brand manufacturers. As you can see from our list, we’ve included some off-brand TIG welders for you to look at. Don’t scoff until you’ve tried it.

Summary

In this guide, we showed you what we feel is the best TIG welder for aluminum, as well as several high-quality alternatives.

By testing more than a dozen different TIG welders in our shop on a range of different materials, we’re sure you’ll find a suitable aluminum-welding machine on our list for your every need.
