Unique Features

With dual processes and dual voltage, the PrimeWeld CT520D makes welding and plasma cutting convenient for users of all skill levels.

Plasma Cutting and Welding Functions

Unlike many portable solutions, this machine includes both welding and plasma cutting options in the same product.

Thick Cutting Functions

The cutter can handle thick metals such as mild steel, stainless steel, copper, and cast iron with no trouble. It cuts through thick metals quickly and only requires infrequent cooling-down periods.

Beginner-Friendly Design

With a simple beginner-friendly design, this machine features easy dial controls for quick setting adjustments while you work.

Thin Metal Welding Capability

This welder includes TIG and stick functions that work well for aluminum and other thin metals. When operated with the right type of gas, it welds almost any type of metal with ease.

Dual Voltage

This machine features dual 110V/220V input power. This way, you can hook it up where you need it most and run it on household currents or operate it with more power.


Performance & Ease of Transportation

Where most dual-process plasma cutter/welding machines fall short in terms of performance, the PrimeWeld CT520D exceeds expectations and adds portability as well.


This machine performs admirably as a welder. Its stick and TIG functions work well right out of the box and handle light to moderate welding tasks without much trouble.

The machine welds hot while running cool and operating for long periods without interruption.

As a plasma cutter, the machine operates smoothly and quickly. Very inexperienced beginners may struggle to start it cutting properly, but with practice, the machine creates impressive results for any user.

Durable components ensure this machine remains a reliable solution for cutting and welding both. It holds up to long-term use and finds its place in professional settings as well as residential ones.

Ease of Transportation

Weighing in at 35.7 pounds, this machine remains surprisingly lightweight and portable despite its three separate included functions.

Most portable welders and plasma cutters weigh about the same as this product on their own without combining processes.

The machine runs on two voltages, making it easy to hook it up and use it from just about anywhere. Its built-in top handle makes lifting and carrying a snap, and its durable casing prevents damage while in transit.


Weld/Cut Quality and Available Options

The machine creates smooth, hot welds whether used as a stick or TIG welder. It provides plenty of forgiveness for beginners learning how to weld and precise adjustments for more experienced users.

Welds created with this machine hold solidly.

As a plasma cutter, the machine’s results rank even higher. It cuts quickly and cleanly with no additional cleanup needed, even on tougher, thicker jobs. It can run for long stretches and stay both smooth and relatively quiet.

The PrimeWeld CT520D comes in just one option. Customers may choose to add the following:

  • Upgraded torches: Some customers prefer to upgrade the torches for this machine rather than use the included ones.
  • Extra consumables: Stock up on consumables so you never have to worry about running out in the middle of a job.

Ease of Maintenance, Repairs & Warranty

The PrimeWeld company provides some replacement parts available for purchase on the company web site. These parts include consumables and accessories but exclude internal components.

Customers should refrain from servicing the internal parts of this machine and should contact a professional repair technician to perform this work instead.

This machine requires routine maintenance every 1 to 3 months as needed depending on the frequency of use. To perform maintenance, unplug the machine for 30 minutes before removing the front cover.

Use compressed air to clean dust and debris from the inside of the machine and its vents.

Check consumables, cables, and connectors at this time and replace any that look damaged or worn. Do not operate this machine with damaged or worn items installed.

The PrimeWeld company offers a three-year limited warranty on welding and cutting products and accessories.

If the machine fails due to manufacturer error, the company provides free replacement during this warranty period.

Can the PrimeWeld CT520D’s welding leads be replaced?

Yes. Customers frequently replace the welding leads on this machine with longer or sturdier options.

What type of gas does the PrimeWeld CT520D need for aluminum welding?

This machine welds aluminum easily when used with pure argon gas. Other types of welding require different types of gas.

Does the PrimeWeld CT520D require an air compressor?

Yes. This machine cannot run as a plasma cutter without an air compressor. It does not require an air compressor for welding purposes.

Price of the Primeweld CT520D

Compared to other portable welding machines, the Primeweld CT520D costs slightly more but remains near the average. In comparison to other portable plasma cutters, this machine remains quite affordable.

Since the machine includes both processes as well as two separate welding methods, it provides an extremely high value for its affordable, entry-level cost.

Beginners and professionals alike find this a budget-friendly portable solution for welding and cutting.
