PrimeWeld CT520D Review

The PrimeWeld CT520D is one of those machines that once you buy, you’ll wonder how you ever managed to live without it.

That’s when I came across the PrimeWeld CT520D. It boasts of more high-quality performance and durability compared to other welders or cutters of the same type.

PrimeWeld CT520D Features and Benefits

Read on to learn more about some of the main features and basic benefits of this product.

3-in-1 Machine

One reason I highly recommend this welder is that this powerful and impressive piece of equipment can do the work of 3 machines. It can function as a stick welder, a TIG welder, and a plasma cutter. Both the stick and the TIG welders deliver current up to 200 amperes.

Plasma Cutter

One of the PrimeWeld CT520D welding machine’s unique features is the 50 amp plasma function, which can cut metals up to half an inch thick. It can also weld at the same time.

It’s a precision cutter and is great at welding various types of metals, such as stainless steel, cast iron, copper, and lots more.

The plasma function is considered a unique feature in both its design and performance. The plasma function doesn’t require the need of any flammable constituents, so it’s not considered a safety hazard.

TIG Torch

The TIG stick welder comes with a welding shape, a deep weld pool, and an easy arc. This torch is perfect for welding various types of electrodes of different acids and basis, such as stainless steel, aluminum, and magnesium.

It comes with a well-designed handle to ensure you have a good grip on your equipment and reduce the risk of injuries.

LED Display

This cutting and welding machine has a LED screen that shows the amp readings. It gave me precise and reliable reading.

Dual Voltage and Dual Frequency

Some areas that use 110V, while others use 220V. This can create a problem for those using welding machines with only one voltage. But the PrimeWeld CT520D can use both these voltages without the need for rewiring.

Another fun feature? The switch between voltages happens automatically and doesn’t require any manual change. The same goes for its dual-frequency function which runs at both 50 and 60 Hz.

Portable and Lightweight

Weighing at just 36 lbs (16 kg), the PrimeWeld CT520D is one of the lightest welding machines on the market. It was easy for me to move it from one place to the next easy and hassle-free.

Its dimensions are 23.6 × 16.8 × 12.8 inches.

Performance and High Speed

It works at a faster speed compared to other welding and cutting machines. I believe that it saves time, costs, and effort for welders and their employers.

Power Efficiency

Just by being 3 machines in 1, the PrimeWeld CT520D is already saving energy and power. This efficient piece of equipment saves up to 85% more power than welding machines of the same type.

Durability and Reliability

You can rely on the PrimeWeld CT520D. It doesn’t suddenly stop as you’re working. This welding machine’s high-efficiency ensures a perfect and complete cutting or welding job every time you use it.

Low Noise Output

The PrimeWeld CT520D is one of the few welding machines on the market that produce low noise output. This reduces distractions, discomfort, and health risks due to loud noise.

Value for Money

Having 3 machines in 1 means you’re saving money. You don’t have to buy a separate cutter, accessories, or other tools. They come together in one convenient package.
Plus, this welding machine comes with a variety of impressive features and functions. All these aspects make it definitely worth your money.

What Do Users Think of The PrimeWeld CT520D

I scoured the Internet and found customer reviews that seemed rather positive.
One customer was happy with the product and PrimeWeld’s customer service.

The Verdict

Things to Consider Before Buying the PrimeWeld C520D

My PrimeWeld CT520D review will show that this isn’t just any welder. Its versatile features and affordable price make this welding and cutting machine a reliable piece of equipment to own.
Here are a few things to consider before buying this welder.

Easily Moved

It should be easy to transport it from one area to another. Being lightweight is a feature that boosts its versatility.

Try a Test Cut

When buying a cutter, you should give it a test cut. Using the same piece of metal sheet, try it at different speeds. Check the quality and final result of your cuts.

The Engine

The engine is one of the first things I look at when buying a cutter/welder. The engine is what dictates the outcome of your project, so it’s important you give it a good look-over.


Each machine requires some type of upkeep. But it’s nice to find one that needs as little maintenance as possible.

Extra Features

I believe that a machine that comes with extra features and tools is number one in my book. You get your money’s worth, plus you have more tools to help you get the job done.
