Reviews of the Top Lincoln TIG Welders

But Lincoln isn’t just a one-TIG-welder wonder; the company has a wide range of TIG welders that outshine many of its competitors. Here’s our reviews of some of the most noteworthy Lincoln TIG welders.

Best Premium - Lincoln Precision TIG K2535-1

best overall rating Precision Ready-Pak 230V TIG Welder 340A

Key Specifications

  • 1/8-inch Welding Capacity
  • 208V/230V Input Power
  • 40% Duty Cycle @ 230A
  • AC Auto Balance

A quick glance at the K235-1’s performance ratings might don’t do it justice. This machine is designed to weld thinner sheets of up to 1/8 of an inch, despite its heavy-duty 230A output. However, the K235-1’s flexibility is where it shines—with a wider current range, you can weld incredibly thin sheets without worrying about melting your workpiece.

Additionally, at its peak output rating, the K235-1 maintains a 40% duty cycle. Additionally, it has a built-in AC auto-balancing system to ensure thinner workpieces don’t melt or warp while exposed to the TIG torch.

Using the K235-1 is hassle-free. With turn-dials instead of a complicated digital interface, you can get started almost immediately with just a few simple adjustments.

Pros

  • Great for novice and experienced users
  • Cleaner welding performance
  • Portable design
  • Versatility

Cons

  • Could weld thicker sheets

Though it may not pack the mightiest of punches, the K235-1 is an incredibly versatile machine that excels at fine-welding thinner sheets.

Best Budget - Lincoln Invertec V155-S K2606-1

best overall rating Invertec V155-S Ready-Pak 120/230V TIG Welder 155A

Key Specifications

  • 3/8-inch Welding Capacity
  • 115V/230V Input Power
  • 30% Duty Cycle @ 155A
  • Soft and Crisp Stick Modes

What truly stunned us the most during our testing stages was seeing the V155-S K2606-1 outclass many of its costlier competition. Even though all TIG welders can stick weld, the K2606-1 takes it to a completely different level.

Equipped with soft and crisp stick welding modes, you can adjust how fluid or stiff the resulting weld puddle. We were excited to try out the soft stick mode and were incredibly happy to see how easy stacking welding beads became.

This machine has a max penetration of 3/8 of an inch at max, which is at par with the best-overall Lincoln TIG welder. It plugs into either a 115V or 230V receptacle to be used anywhere at any time, and it has a pretty nice 30% duty cycle.

Pros

  • Excellent beginner-friendly TIG welder
  • Straightforward control board
  • Comes with carry case
  • Great TIG and stick functionality

Cons

  • Could be lighter

The K2606-1 surpasses our expectations of what a budget-friendly TIG welder can do in nearly every way. It’s a definite must-have for first-time buyers looking to gain experience in both TIG and stick welding.

Lincoln Electric LE31MP K3461-1

best overall rating Lincoln Electric LE31MP MIG Welder with Multi Processes - Transformer, MIG, Flux-Cored, Arc and TIG, 120V, 80-140 Amp Output, Model Number K3461-1

Key Specifications

  • 1/8-inch Welding Capacity
  • 120V Input Power
  • 60% Duty Cycle @ 140A
  • Fully Adjustable Drive System

The K3461-1 is another incredibly user-friendly TIG welder with very few bells and whistles. The lack of extra frills makes it a viable option for novice welders looking to level up their welding capabilities.

The K3461-1 plugs into any standard 120V wall outlet, and it delivers a 1/8-inch welding penetration for basic home repair jobs. As for commercial use, we wouldn’t recommend this machine due to its low peak output and thinner welding.

One of the greatest frustrations of welding is dealing with the drive system and tangled wire. With the K3461-‘s fully adjustable drive system, you won’t have to worry about shaved, crushed, or tangled wires when replacing spools ever again.

Pros

  • Extremely user-friendly
  • Welds thins sheet metal with ease
  • Easy to maneuver and transport
  • Worry-free drive system

Cons

  • Could deliver deeper penetration

If you need a simple TIG welder for fixing up your home’s HVAC system or patching corroded parts on a lawn mower, the K3461-1’s shallow welding performance should suffice.

Lincoln Precision TIG 225 K2533-2

best overall rating TIG Welder, Precision TIG 225, 208/230VAC

Key Specifications

  • 5/32-inch Welding Capacity
  • 208V/230V Input Power
  • 40% Duty Cycle @ 230A
  • Micro-Start

The K2533-2 is a DC-only TIG welding machine, meaning that it will work beautifully on ferrous metals. As for aluminum, you’re going to have to consider other models, since DC welders are far too aggressive for non-ferrous materials.

The K2533-2 can weld 5/32-inch sheets with a single pass of the TIG torch, while working at a 40% duty cycle at max power. It would appear that the K2533-2 is a simple TIG machine for more challenging jobs, but there’s more to this TIG welder than meets the eye.

Equipped with Micro-Start technology, the K2533-2 produces a more stable arc, even when operating at lower amp ratings. This system leads to more appealing beads, even by inexperienced operators, without sacrificing quality.

Pros

  • Easy to start and use
  • Great penetration
  • Durable construction
  • Efficient duty cycle

Cons

  • Not a portable TIG welder

Whatever ferrous sheet metal you have in front of you, the K2533-2 will weld it in no time at all.

FAQs

1. Are Lincoln TIG welders any good?

You can bet that any Lincoln-made TIG welder will surpass your expectations by a wide margin. Lincoln keeps a close eye on the market by interviewing welding machine operators—from greenhorn welders to those with more than 40 years’ worth of metalworking experience under their belt—in order to produce what the market wants. Whether you need a hard-hitting machine or one for light-duty repairs at home, there’s a Lincoln TIG welder for every demographic.

2. Where are Lincoln welders made?

Even though Lincoln outsources the manufacturing of several models abroad, a majority of their TIG welder models are made in the US of A. This gives Lincoln the ability to pay close attention to the entire manufacturing and assembly processes before being shipped out to your door. Plus, their customer service reps are all stationed in the US, and they’re ready to help in any way possible.

3. How do Lincoln TIG welders compare to Miller TIG welders?

During our trial phase, more of our team members found Miller-made TIG welders to provide more value for their investment. However, they’re also considerably more expensive, even their entry-level lineup of TIG machines. That said, Lincoln’s welders are definitely some of the best you can at a reasonable price. That includes those made by Hobart and Everlast.

4. How much should I spend on a TIG welder?

Though one of the most commonly asked question, we can’t answer that for you. Look, we’d like to tell you that expensive TIG welders guarantee better performance as opposed to their cheaper counterparts, but that’s not always the case. With an influx of cheaper, Chinese-made goods entering the market, we admit that you can find a top-tier model in an ultra-budget-friendly price range. Our list of the best TIG welder under $1,000 should give you a good idea of what we mean.

Summary

After research, we were finally able to compile a meaningful list containing some of the best Lincoln TIG welders available today.

This includes some older models from previous generations that remain relevant to this day.
