Miller Diversion 180: Detailed Review and Specifications

If you are new to TIG welding and are just getting started, you should invest in a good welder. The Miller Diversion 180 TIG welder comes highly recommended by me.

Whether you’re a beginner or a seasoned welder, you’re surely aware that TIG welding produces the most beautiful welds. But, at the same time, it takes longer to complete.

Learning also takes perseverance and patience. So, in this Miller Diversion 180 TIG welder review, I’ll explain why having a decent machine on your side is so crucial.

The Miller180 is a flexible machine with enough power for modest work. Now let’s get into some additional specifics.


A brief review of the miller diversion 180

The Miller Diversion 180 TIG welder is a welding machine designed with novices in mind. It can accept both 120v and 240v input power and can be upgraded if necessary. It allows you to focus on applications that require a little more processing power rather than basic tasks that are ineffective.

However, its primary goal remains simple: shop work, garage work, DIY projects, and other minor tasks. However, a Miller product will undoubtedly meet or exceed your expectations in terms of quality. It is one of the greatest TIG welders for beginners but one of the most expensive.

Its price is a little higher because of the brand and the great quality of its construction. The Miller Diversion 180 TIG is of exceptional quality, and you may be confident that you have purchased a dependable welding machine.

However, while having the greatest build and performance in the beginner category, it is still a touch pricey, in my opinion. It will, however, not leave you hanging.

The Cons

  • They are very expensive
  • They have a low duty cycle

Performance in Power and Welding

The Miller 180 welder has more power than you’d think from a beginner-level machine. It’s one of the more powerful welders, with a 180 amp output that’s more than enough for enthusiasts and beginners.

However, the duty cycle suffers from a maximum output of 180 amps because it only offers 10%. However, when the duty cycle is increased to 20% at 150 amps, things improve slightly.

These Miller 180 welders have a dual voltage input and can produce a maximum amperage of 125A at 115V. It is especially advantageous because novice units don’t produce nearly as many amps at 115v.

1. It’s Simple to Use and Setup

The Miller Diversion TIG welder is ideal for novices because it is simple to operate. The setup is straightforward, and you may begin working in as little as 20 seconds. All you have to do now is select the type of metal you’ll be welding and the thickness on the control panel, and you’re ready to go.

The thickness will show you how much current you need for the work while selecting the metal will switch it between the AC DC TIG welders. If that sounds too complicated, there’s still the DVD with tutorials and an easy-to-follow handbook to guide you.

2. The Features of Miller Diversion 180

The Diversion 180 TIG welder is chock-full of handy features. Some of these can even be found in higher-level units.

First, it is an AC DC TIG welder since it can do both AC and DC welding. It also has a preset AC balance and frequency, so it adjusts the post flow automatically based on the amperage.

For expert welders, this feature is unnecessary, although it is useful for beginners. Following that, the Miller Diversion 180 has a High-Frequency arc start and an advanced AC square wave.

These capabilities will let you generate welds that are extremely smooth and of high quality. They’re also commonly found on high-end TIG equipment. With the foot pedal and the included multi-voltage plug, altering input voltage is a breeze.

Even with all of the capabilities I described, this is hardly a professional machine. To be classed as such, it still lacks AC balance, frequency, and pulse parameters. However, the available capabilities are more than sufficient for beginners and will also prepare them for the transition to a more serious welding machine.

Comparing the Built Quality and the Price of the Miller Diversion 180

As I previously stated, because this is a Miller product, the Miller TIG 180 has great build quality. As a result, nothing about this machine has a cheap feel about it.

In reality, it looks fantastic and is an amazing piece of TIG welding equipment. Furthermore, both the foot pedal for foot control and the other TIG torch is of great quality.

However, there is a catch: the price. This TIG welder is more expensive than several beginner lightweight welders, and it’s even more expensive than some professional welders. It is unsurprising given that it is a USA brand targeted at a certain market, so you should be aware that you are paying for quality.

Frequently asked questions:

  • Who is supposed to buy the miller diversion 180 welders?

The Miller Diversion 180 welder is designed for novice welders. Hobbyists and beginners can benefit greatly from this machine if they need a machine for less difficult jobs, such as around the house or DIY projects.

On the other hand, professional welders will not benefit from this machine because they most likely already have a far superior one in their arsenal. However, other items from the manufacturer, like the Miller Dynasty brand of welders, may benefit them.


To sum up my Miller Diversion 180 review, this is one of the more expensive TIG welders available at the novice level. However, as you can see from the Miller Diversion 180 capabilities review, the brand is what matters. It has incredible features that make arc welding, stainless steel, and aluminum welding considerably simpler for beginners.

As you can see from the weld puddle you’ll get, the results speak for themselves. But, aside from dealing with a variety of materials, it’s the build quality that matters. It’s very nicely crafted, and it’s a good machine to have in your set, thanks to the dual power supply of 120V and 240V.
