PrimeWeld Ct520d
TIG Welder Review

84 Reviews $399.00

In our search for the best TIG welder for the money, one unit stood out as the clear winner: The PrimeWeld Ct520d.

This 3-in-1 welder and plasma cutter offer excellent performance at a reasonable price. On top of that, PrimeWeld’s amazing customer support ensures you’ll get your money’s worth.


The PrimeWeld Ct520d is a 3-in-1 unit that performs plasma cutting, TIG welding, and stick welding. It can cut metal up to 1/2″ thick with the plasma cutting feature.


The Ct520d TIG machine runs off a 110V or 220V power source. Reviewers reported a better welding experience at 220V, but the unit was still quite capable at 110V.

The unit comes wired for 220v, but an adapter is available from PrimeWeld and other retailers like Home Depot.


Customer reviews of the Ct520d highly praised the unit’s strong performance, especially for the price. It can be used for welding aluminum as well as stainless steel and copper.

Many users mentioned that the plasma cutting feature worked very well and exceeded their expectations. A foot pedal (included separately) offers extra control.

Customer Service

Dozens of reviewers mentioned PrimeWeld’s high-quality, US-based customer service. Many purchasers had personal interactions with the company’s owner, Mike, and all were positive.

He was more than willing to answer questions before the sale and provided excellent post-purchase support. It’s rare to see this level of dedication for a product at this price range.


The PrimeWeld Ct520d includes a 3-year warranty.

PrimeWeld frequently sent replacement parts/units for free (including shipping) and never made customers jump through hoops to get the help they needed.

The simple truth is that TIG welders of any price range are going to have the occasional issue, which is why good service is so important.

The Next Step Up

AHP AlphaTIG 200X

157 Reviews $720.00

Welders who need more robust performance should consider the AHP AlphaTIG 200X.

This welder has more power and features than the PrimeWeld and is better suited to commercial and industrial environments.

Keep in mind that the AlphaTIG 200X is more of a purpose-built unit, so it doesn’t offer a plasma cutting feature. Many pros will already have a dedicated cutter in their shop, so this will be a non-issue.
