The welder is the largest single cost of starting a permanent jewelry business, so the first real question most new operators face is how little they can spend without buying a machine they'll regret at an event. The Sunstone Zapp is Sunstone's answer to exactly that: the lowest-cost way onto the platform that most working artists cite, priced at around $1,249 as of August 2026. It is a pulse-arc welder, not a spot welder. It fuses chain ends with a fast electrical pulse, no flame and no solder.
What you're buying at the entry price is a genuinely name-brand machine with a real safety net: a 3-year manufacturer warranty, US-based phone support, and an in-stock supply of tungsten electrodes. What you're not buying is range. The Zapp tops out at 10 joules, which is plenty for gold-filled and fine sterling chain but short of the heavier links the pricier Sunstones reach.
Sunstone Zapp specifications
Per Sunstone's product page, the Zapp is a compact benchtop pulse-arc welder aimed squarely at first-time operators. The numbers that matter:
- Energy range: 3-10 joules in single-joule increments.
- Interface: a simple dial with no touchscreen, which keeps the learning curve short.
- Argon: argon-ready; it connects to an argon source in seconds for cleaner welds, though argon is optional to start.
- Warranty & support: 3-year manufacturer warranty, US-based customer service, Made in the USA.
- In the box: the welder, power adaptor and cord, three 1 mm electrodes, argon tubing, a welding stylus, shaded safety glasses, a precision ground clip, and a metal practice card, enough to start welding practice chain the day it arrives.
Sunstone's entry machine: a 3–10 joule pulse-arc welder made and supported in the USA, argon-ready, and backed by a 3-year manufacturer warranty. The lowest-cost way onto a name-brand platform with real phone support.
- 3–10 joules in single-joule steps, enough for gold-filled and fine chain
- Argon-ready; connects to an argon source in seconds for cleaner welds
- US-based phone support and tungsten electrode supply
Who the Zapp is for
The Zapp makes the most sense for the operator whose plan is to start on gold-filled and fine sterling chain, the metals that carry most pop-up and market bookings, and who wants name-brand support without a four-figure leap. If your first season is craft fairs and bachelorette parties welding delicate chain, the 3-10 joule range is not a limitation you'll feel, and the money you save versus the mPulse can go into sellable inventory.

Where it earns its keep
- Name-brand support you can actually call when a weld fails at an event
- Simplest learning curve of the premium machines
- Argon upgrade path without changing platforms
What to watch
- Narrower energy range than the mPulse or Zapp Plus 2, so less headroom for heavier links
- No touchscreen or fine sub-joule tuning
Zapp vs Zapp Plus 2: where the entry machine stops
The honest limit of the Zapp is its ceiling. It reaches 10 joules; the Zapp Plus 2 reaches 30, across 30 settings, for around $1,699. That 20-joule gap is not academic: it's the difference between a machine tuned for gold-filled and fine chain and one that welds the full standard permanent-jewelry metal range, including heavier links. The Zapp Plus 2 also swaps the plain dial for a digital energy dial you can lock in place with a tap, and at 1.9 lbs it is the lightest, most travel-friendly Sunstone. Same US manufacturing, same 3-year warranty on both.

If you already know you'll sell across metals, or you value the lock-in digital settings for consistency across a long event, the Zapp Plus 2 is worth the step up.

The verdict
The Sunstone Zapp does one job well: it gets a new operator onto a name-brand pulse-arc platform, with real support and a 3-year warranty, for the least money Sunstone asks. Buy it if you'll weld mostly gold-filled and fine chain and want the lowest-risk entry. Skip it for the Zapp Plus 2 or Orion mPulse if you need the full 1-30 joule range from day one. Either way, run the payback math first: operators commonly report roughly $60-90 of profit per welded bracelet, so a $1,249 machine is a countable number of events, not a mystery.

Sunstone Zapp FAQ
What is the joule range on the Sunstone Zapp?
Per Sunstone's product page, the Zapp delivers 3-10 joules in single-joule increments. That range covers gold-filled and the finer sterling chain most new operators start with. Heavier links and the full standard-metal range are where the 1-30 joule Zapp Plus 2 and Orion mPulse earn their higher price.
Is the Sunstone Zapp good for beginners?
It is built for them. Sunstone markets it as its entry welder for new permanent-jewelry artists. The dial interface is simple, it is argon-ready out of the box, and it comes with a 3-year manufacturer warranty and US-based phone support you can reach when a weld fails at an event. The main trade-off is the narrower 3-10 joule range versus the pricier machines.
How much does the Sunstone Zapp cost?
As of August 2026 the Zapp lists at around $1,249 direct from Sunstone. It is the lowest-cost way onto the Sunstone platform, sitting below the Zapp Plus 2 (from about $1,699) and the Orion mPulse (from about $2,999). Check the linked product page for current pricing, which drifts.
Zapp or Zapp Plus 2: which should I buy?
Buy the Zapp if you will mostly weld gold-filled and fine chain and want the lowest name-brand entry price. Step up to the Zapp Plus 2 if you want the full 1-30 joule range for heavier and mixed metals, a digital dial with a lock-in setting, and the lightest, most portable Sunstone. Our head-to-head and the welder roundup lay out the full trade-offs.
