Miller TIG Welder Products Comparison Table

Miller Syncrowave 210 TIG Welder 

miller tig welder-TIG Welder, Syncrowave 250DX, 230/575VAC


  • Worth every penny, next to the Millermatic 252, and Miller Spectrum 625 X-Treme makes a power house.
  • Excellent machine!


  • Expensive

If the Maxstar 150 doesn’t have the versatility you are looking for, consider the Miller Syncrowave 250DX. This top of the line model comes equipped with every feature you could need, along with the quality of Miller tools.


This powerful machine can function with both AC, DC and plasma cutter capabilities. It has an impressive 60% duty cycle at 200A, with an amperage range of 3-310. It has great control and good arc stability.

It is not considered a portable unit by any means and is considerably heavier than the Maxstar 150. However, if you are looking for sheer power and versatility, the Syncrowave represents some of the best TIG welders available. It has a lot of added features, including line voltage compensation and built-in preflow/post-flow.


With all the added features and range of use, it’s not surprising this unit is quite expensive. It usually is sold for over $8,000. Just like that Maxstar 150, don’t be afraid to look for used models of this extremely durable machine.


One of the highest rated, top of the line TIG welders, you can’t go wrong with the Syncrowave 250DX. Most of the negative reviews of this welder are with the price, which is considerably more than many of its competitors.


If you want a heavy-duty TIG welder at less cost, consider the Lincoln Electric Precision 225. This high-end machine is also quite heavy, at 263 pounds. It has an impressive amperage range of 5-230 and is also capable of pulse welding. However, it has a very low duty rate of 10% when you are using a large amperage level.

  • Advanced inverter technology with Auto-Line technology
  • Maximum flexibility


  • Expensive

A great in-between choice, the Miller Dynasty 200 offers more power than the Maxstar 150 with less bulk and cost than the Syncrowave 350DX. It’s flexible, dependable and versatile enough for most of your welding needs.


This mid-range machine is capable of AC and DC welding and has a great arc performance. It has a respectable duty cycle of 40% at 150A. This TIG welder is far less expensive than the top of the line models but is still too bulky to be considered a portable welder.


You can purchase this model for around $3,800, considerably less than the Syncrowave 250DX, but it may be more power than necessary, depending on your welding needs. Check for deals on used or refurbished models.


This TIG welder is rated favorably, particularly with the AC and DC option. It has a lot of power for its size, weighing only 45 pounds.


The Everlast PowerTIG 250 is a reasonable choice for another mid-range TIG welder. This machine has a good amperage range, AC, and DC functions and is considerably less expensive than the Miller Dynasty 200 SD. It has a pulse function and an easy setup.

This Chinese-made machine is a bargain but is not made with the same high-quality parts as a Miller Electric welder. If you are looking for an inexpensive mid-range alternative, the PowerTIG 250 is a good choice.

As you think about the types of welds you will be making, choose the TIG welder that best matches your needs. If you have a dedicated shop or workspace and will be working with steel and aluminum frequently, the Syncrowave 250DX is a great investment.

However, if you are a casual welder, consider the Maxstar 150. Consider the types of welds, as well as the amperage range and duty cycle that you will need for your TIG welder. Be sure the types of welds you are making aren’t better suited for a MIG welder. Regardless of the function, Miller Electric welders are some of the highest-quality machines on the market. Compare each of the welders, along with their competitors, and be confident that you have chosen a high-quality TIG welder that will serve your needs.

What Is a TIG Welder?

There are many different types of welders, each used for a variety of applications. TIG stands for “tungsten inert gas.” These welders use a tungsten electrode and an inert gas, which is usually argon. It can be used with both AC, alternating current, and DC, or direct current, power sources. TIG welding is very precise and does well with both steel and aluminum.

Do I Need a MIG or TIG Welder?

It depends on your project. MIG welders do not need a second hand to weld so that you can operate them more quickly and efficiently. MIG stands for “metal inert gas.” MIG welding can provide a sturdier weld. The downside to MIG welding is that the result is not as polished as TIG welding. TIG welding uses a separate rod to feed into a welding pool. The result is a much slower weld, but a finer finish. TIG welding works great for smaller projects that need more attention to detail.

Features of a Miller TIG Welder

Once you understand the basic principles of TIG welding, there are several key features you need to know in order to purchase the most effective machine. Consider the types of welds you intend to make, as well as the area you will be working in the most.

Some welders do not have a large variety of options, or they are bulky and different to transport. Once you have the type of welding in mind, take a look at these important features.

Comfortable, Practical Design

TIG welding is a very precise operation. You will want a machine that is easy to use, comfortable to hold and can withstand heavy use. Consider the material you will be welding.

If you are planning on welding aluminum, you may need to control the amperage quickly, making an amperage pedal a vital feature; otherwise, the aluminum will soon overheat. A foot pedal is often more comfortable to use with any project, so if you are planning on welding extensively, it will also be a key piece.

Duty Cycle

This is expressed in a percentage and shows the time the welder can run. 100% would be a full 10 minutes, so 30% duty cycle would mean the welder can operate at the set output for three minutes.

A high-quality welder might have a duty cycle over 60%, while more inexpensive machines could have a rate under 20%. If you do not plan on operating your TIG welder for extended periods, you might consider a lower duty cycle. However, if you use your welder consistently, you will want to purchase a high duty cycle model.


Depending on the materials you will weld, you may need either DC, AC or both types of control. DC works well for harder metals, like stainless steel. If you are welding aluminum, magnesium or any other self-oxidizing metals, you will want to use an AC TIG welder.

If you are only using your welder for one type of metal, the ability to switch is irrelevant. For those who weld a variety of materials, or are unsure what welding projects they may encounter, an AC and DC welder might be a wise investment.

Pulse Welding

Some TIG welders come with a pulsing feature, which allows the metal to cool down in between pulses. Some metals can overheat with constant welding, so if you have trouble with the thinner material, then a pulse feature is a great option.


TIG welders come with an amperage range. A higher level of amperage is best for thicker materials, but thinner metals require a lower amperage level. Some welders have a range between 5A - 200A. Decide what thickness of materials you are planning on welding.

You will save a lot of money by choosing a TIG welder with a shorter range, but you also limit its capabilities. Be careful using a high amperage, because this can damage the material. While larger machines appear to have higher quality features, choose an appropriately sized welder that fits your needs.

Low Amperage Considerations

Some welders do not function as effectively under 10A. These low ranges need a very consistent and stable arc. Machines that operate well in low amps are also easier to start. Considering that most TIG welders work with thinner metals, you will want a welder that is able to start well, run smoothly and fill craters easily in amps under 10.

With all of these considerations, let’s take a look at a high-quality TIG welder: the Miller Maxstar 150.

Miller Maxstar 150 TIG Welder Information and Buyer’s Guide

When you are choosing a tool, you should make sure it is the very best option for the job. Whether you are familiar with welding or a beginner, finding the right type of welder is crucial to both your effectiveness and safety. Here are a few features of a TIG welder, and a comprehensive review of a very highly rated model, the Miller Maxstar 150.
