Permanent Jewelry and the Unbranded Machine: Everything You Need to Know
New permanent jewelry artists ask about the "Unbranded machine" as a welding solution for permanent jewelry. In short, Established artists already know this industry secret, that the Unbranded machine, for permanent jewelry, is not a good choice. As a welding engineer, I know some things you must be aware of before making a purchase decision.
A simple comparison between the Unbranded machine and the Zapp Plus® 2 permanent jewelry welder™ makes clear this one point: Don’t invest your dollars in the Unbranded machine.
I organized my comparison into categories that truly matter, like quality, safety, weld consistency, warranty, among others. Here’s what you must know:

A Pig with Lipstick is Still a Pig
The Unbranded machine is sold by at least a dozen different sellers. Some of these sellers have placed their logo on the Unbranded machine, changed the case colors, or relabeled the dental lab buttons.
Putting lipstick on the Unbranded machine doesn’t improve performance. The Unbranded machine will perform like the decades-old dental and ortho lab machine it is—regardless of what logo you may or may not find on the front or sides.
The Bottomline
Every experienced permanent jewelry artist will agree: The Unbranded machine is not a good solution for permanent jewelry. Avoid that path and save yourself time, frustration, disgruntled customers, and money.
The most important investment you’ll make in your permanent jewellery business is your welder, the foundation of your business. If you pinch pennies on your foundation, don’t be surprised if your business takes a tumble. An investment in the Zapp Plus 2 is clearly the better choice than the unbranded machine.
