Best Premium - Miller Syncrowave 250DX

best overall rating TIG Welder, Syncrowave 250DX, 230/575VAC

Key Specifications

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

As a premium TIG welder, the Syncrowave 250DX is best suited for use in commercial-line work rather than at-home welding, despite its 110V input compatibility. It has a quarter-inch welding capacity with easy-to-control power settings to produce beautiful works of art.

The 250DX comes with Squarewave technology, which isn’t anything new in the Miller lineup. Still, it provides greater stability at all amp output levels, allowing users to weld all sorts of sheet thickness and materials, including ultra-thin aluminum.

The control interface is a lot more complicated than most, but it offers a wide range of customizable features to enhance welding performance and quality. As we warned before, this machine should be used specifically for commercial-duty jobs.


  • Excellent welding performance
  • Maximum customizability
  • Great balance and arc control
  • Smooth starts every time


  • Not beginner-friendly

Admittedly, the Syncrowave 250DX isn’t for everyone, especially when considering its premium-grade quality at a premium-level price.

Key Specifications

  • 3/16-inch Welding Capacity
  • 120V/240V Input Power
  • 30% Duty Cycle @ 90A
  • Hot Start Technology

Here’s a more all-around, user-friendly model that’s coincidentally our favorite budget-friendly Miller TIG welder: the Maxstar 161 STR. This machine has a welding capacity of up to 3/16 of an inch with every pass of the welding gun.

It starts at 5 amps, which is ideal for TIG welding thin sheets without melting your workpiece. It runs on either 120V or 240V, allowing you to use it for a number of different jobs, including auto parts fabrication.

With Hot Start Technology, this machine automatically removes sticky electrodes out of the equation. This, ultimately, lets you utilize tungsten more efficiently with considerably less wastage.

This overview video will show you the simplicity of the Maxstar 161 STR.


  • Easy to use
  • Weighs just 13 pounds
  • Dual-voltage TIG welder
  • High efficiency electrode usage


  • Not ideal for heavy-duty welding jobs

As the most budget-friendly Miller on this list, the Maxstar 161 STR is an excellent TIG and stick welder for beginners and basic home repair projects.

Miller Diversion 180

The Diversion 180 is another one of Miller’s light-duty TIG welders. It has a 3/16-inch welding capacity, but with AC and DC capabilities, you can weld a wide range of metals, including copper and alumium, from a single machine.

This machine utilizes inverter technology. If you need to TIG weld outdoors or in a place without access to a 120V or 240V receptacle, the Diversion 180 plugs directly into a portable generator without issue.

The auto-postflow gas control feature eliminates the need to adjust gas outflow by automatically adjusting the delivery rate based on amperage. This is a handy feature for those just getting started in TIG welding.

Learn the ins and outs of the Diversion 180 by watching this video.


  • AC and DC TIG welding capabilities
  • Advanced cooling system
  • Durable torch design

1. Should I choose Miller?

As you can see from our list, Miller provides several types of TIG welders built different applications, from basic home maintenance to heavy-duty metalworking. The incredible performance of each model really speaks volumes about what Miller is capable of creating. If you ask the market which brand makes the best TIG welder, an overwhelming majority of them will vote Miller over the likes of Hobart, Lincoln, and Everlast, and we’re inclined to agree.

2. Why are Miller TIG welders so costly?

We’re not 100% sure why, but since a majority of their products being manufactured on US soil, this might be a significant factor in price. However, Miller has outsourced the production of their newer models to overseas partners, but with Miller’s extreme quality standards, we’re excited for the next batch of cheaper Miller products that leave their Asian manufacturing plants.

3. Should I get a TIG welder?

Only you can determine whether your life will be easier with a TIG welder or not. Admittedly, TIG welders are more difficult to use as opposed to MIG welders, but they produce aesthetically beautiful welds with very little cleaning afterward. That said, you can enjoy the best of MIG and TIG welding by choosing either the Multimatic 215 or the Syncrowave 210 TIG MIG.

4. How reliable are 3-in-1 TIG, MIG, and stick welders?

The main benefit you get from a 3-in-1 (or a 4-in-1 if it can use flux-cored wire) over a TIG and stick machine is not only the versatility of welding a wide range of materials but also fewer tools to maintain. Plus, the added benefit of fewer tools taking up less floor or countertop space in your garage is a tremendous plus for those with less spacious work areas. In terms of performance, the Multimatic 215 and Syncrowave 210 TIG MIG work beautifully in all three departments.


After spending more than 3 months testing out 10 different Miller models, we’re sure you’ll find our picks of the best Miller TIG welders to be to your liking.

The Miller Multimatic 215 is a surefire win for inexperienced and veteran welders alike.
