What Is the Miller Syncrowave 250 DX and What Does It Include?

Let’s get the basics out of the way so we know what kind of welding machine we are working with. The Miller Syncrowave 250 DX is a single-phase TIG/stick welding power source that can easily transition between aluminum TIG, stainless TIG, TIG AC/DC and stick welding.

This model handles TIG, stick, pulsed TIG, and air carbon arc processes. Intended for light industrial applications, this machine is designed for the experienced welder who is ready to tackle more heavy-duty projects that require optimum control and finesse.

While the Miller Syncrowave also comes in a 350 LX model, the 250 DX is still an excellent choice. There are three purchasing options when it comes to this model, so we have outlined exactly what you will get with each option so you can buy confidently.

Syncrowave Power Source Standard Model

The Syncrowave Power Source standard model includes the Syncrowave 250 DX welder with Dinse-style connectors. This is exactly what we have described thus far so you get the TIG and stick capabilities.

Keep in mind that the TIG torch and power cord are not included.  This is bare bones, so if you already have a lot of the accessories you need from another welder it might be best for you to stick with the standard model and not worry about the extra bells and whistles.

TIGRunner Package

The TIGRunner Package includes the completely assembled standard model, but it also comes with the Coolmate 3CS cooler, running gear and RFCS-14 HD remote foot control.

These features will help keep your new welder running smoothly without overheating while also giving you the additional control that remote foot operation affords. This welder model is designed to allow the optimum accuracy possible, so this package may be perfect for you to reinforce that precision.

Foot Control Complete Package

The Foot Control Complete Package includes everything in the TIGRunner package in addition to four gallons of TIG coolant to keep that Coolmate 3CS cooler going strong and a water-cooled torch kit that includes a TIG torch (great if you do not have one already, or if you need a replacement).

You also get a torch connector as well as a cable cover, accessory kit and flowmeter regulator. This package also throws in a gas hose, work clamp and Dinse-style connectors.

This Foot Control Complete Package really has it all. Oftentimes when welders are looking for their next welding machine, many accessories wear out along with their older machine. Even if you can still get some use from the odd gas hose or cable cover, it's safer to go with a complete package.

This is to ensure the full system is running efficiently and safely. As with most complex machines, a welder will operate at its best and provide best results. The only thing not included in the complete package is a power cord, and most welders have one of those lying around somewhere.

What Kind of Pricing Should You Expect?

Pricing varies depending on where you buy and, of course, the package you choose. Look into local shops that carry the model you want and compare prices. Some stores may offer deals or coupons to make it less expensive for you to get your dream welder.

If you are also a long-time customer of Miller, it is definitely worth trying to get a discount for your brand loyalty as they will appreciate a consistent and passionate customer.

What Makes It Unique?

Even if you choose to start with only the standard model, the starting price is quite hefty. However, if you are going to invest in your own TIG/stick welder and want the best, the price is more than worth it. The Miller Syncrowave 250 DX has unique features that will make you want to buy the complete package. You can be sure a Syncrowave will last through years of projects with precision and safety.

The purpose of this heavy-duty welder is to offer safety and ease of use. You spend time on actually creating, mending or building, depending on your goal. Let’s break down exactly what we are talking about so you know what to look for in the machine’s build.

AC Balance Control

For starters, the AC balance control is designed to give you a high-quality weld since it provides adjustable oxide removal. Your welds will look professional with this feature backing you. This is also a great feature if you plan to use the Syncrowave for metal art.

You can also choose from three levels of TIG starts based on the tungsten size and application. They range from soft, medium to hot, by using the Syncro Start feature. The adaptive Hot Start, is a great because it provides good arc strikes without sticking when you are stick welding. This model also reduces tungsten and material contamination with its high frequency for non-contact initiation. Nice, right? It gets better.

If you are looking for better control and a more intelligent design for your projects, you will love the next features. The digital welding meters not only display amperage and voltage as you work, they also have last procedure recall. This saves you time and energy, enabling you to achieve higher accuracy as well as allowing you to easily repeat a weld exactly.

With the flip of a switch, you can move seamlessly between aluminum TIG to stainless TIG to stick welding. It is so easy because you don’t have to waste precious time setting up your machine to reach the exact setting you want. Instead, you can focus on your craft, which is what the Syncrowave 250 DX is all about.

What Projects Should This Model Be Used For?

The Syncrowave 250 DX is designed for light industrial use. Projects can range from DIY for the home hobbyist to creating metal sculptures. This TIG/stick welder’s precision and control provide a professional finish that any artist would aspire to.

However, you can also use this advanced welder for automotive restoration and high-purity processing. It can also be used for farm and ranch maintenance, infrastructure, yacht customization, restoration and/or construction. The possibilities are endless with this Miller Syncrowave model.

How Does It Compare?

Even though there are similar models from competing brands, the Miller Syncrowave 250 DX has more accessible service locations than other brands. This is an important consideration when buying a new welder.

While this is a high-quality machine, any welder will need replacement parts or professional maintenance if something does not work. When you need maintenance done you will appreciate convenient locations that can service your equipment. Competing brands such as Lincoln may not have as many nearby service locations as Miller.

With the Syncrowave , you have the power to take on more heavy-duty industrial jobs such as construction and infrastructure. It is so user-friendly with the finesse of a smaller machine. It also handles delicate work like metal art and sculptures. This newer version of the model offers even more precision capabilities.

What Do We Think?

When you are purchasing a welder, it's wiser to spend on a model and brand with trusted quality and usability. The Miller Syncrowave 250 DX works with the user and provides an interface. The interface makes project time and energy efficient compared to other models.

As you consider which package to buy, we recommend looking at your workshop and assessing your needs. There is a large price difference between the standard model and the other packages that are available. We suggest committing to either the standard model or the Foot Control Complete Package.

The standard model will give you the heart of the Syncrowave 250 DX. It is without the extras that are not absolutely necessary if you already have perfectly usable parts in your workshop. With its more modest price point, you can have the welder of your dreams without overspending.

TIGRunner vs Foot Control Complete Package

If you need extras and undecided between the two remaining packages, we suggest skipping the TIGRunner. Go for the Foot Control Complete Package. It is because although the TIGRunner is more affordable than the Foot Control Complete Package. Even though it does not include extra features, you may not need right now. So Foot Control Complete Package is a better deal.  

The price difference between these two options is not as drastic as the difference between either of those and the standard model. Many of the extra parts you get with the Foot Control Complete Package are items you will need to replace at some point anyway.

In other words, you get more bang for your buck with the Foot Control Complete Package than with the TIGRunner. There will be spares to replace worn-out equipment with parts that came at a bundled price. This is a great way to save money in the long run. The Foot Control Complete Package provides you with every piece you may need to begin your projects immediately.
