The decision most Sunstone buyers face is not which brand but which tier. The Zapp is a 3–10 joule entry machine for $1,249: the right tool if fine chain is your business. The Orion mPulse is a 1–30 joule studio flagship from $3,199: the deliberate choice for heavier-gauge rings, mixed-metal menus, and operators who already have the volume to justify it. Both prices live-checked on Sunstone’s product pages in October 2026.
For most first-season operators, the Zapp is the honest starting point and the mPulse is deliberate overkill until volume and metals make the case. Here is where that line sits.

The joule tier: why ring gauge decides the machine
Heavier rings take more energy, so the chain you plan to sell determines the welder you need. Sunstone’s jump ring weld settings chart (October 2024) gives starting settings for 20 to 26 gauge rings on the Zapp, the original Zapp Plus and the mPulse 2.0:
- 14/20 gold-filled: 3 to 9 joules on the mPulse 2.0. On the Zapp, 5 joules at 24 gauge and LOWEST POWER at 26, which is exactly where most first-season menus live; 20 gauge takes MAX POWER with multiple welds.
- Silver: 2.5 to 7 joules on the mPulse 2.0. The Zapp covers 22 to 26 gauge (22 gauge with multiple welds), but 20 gauge silver takes MAX POWER with multiple welds. That is where the 1–30 joule Zapp Plus® 2 and mPulse give you headroom.
- Platinum and rings heavier than 20 gauge: not on the chart, so we give no figure. The mPulse reaches the full 1–30 joule range with 0.5-joule fine steps between 1 and 15 joules for precision across gauges, and the chart lists half-joule settings for the mPulse 2.0.
If your menu is 24 and 26 gauge chain, the Zapp’s ceiling is not a constraint the chart says you will hit. If you plan to offer 20 or 22 gauge rings, the ceiling is real, and sizing up now costs less than buying twice.
The scale question: when volume justifies the mPulse
Owner Olivia adding permanent jewelry to an existing salon is the operator the mPulse is designed for. She already has foot traffic and group bookings; her break-even on a $3,199 machine is faster than it would be for a first-time pop-up operator, because the appointments are already coming. The touchscreen and Tru-Fire Technology reduce time between customers; the fine 0.5-joule steps keep welds consistent when she is switching between metal types across a full day of walk-ins.
For an operator on a first-season schedule of weekend markets and bachelorette parties, that interface premium is real capital with a longer payback. The Zapp’s dial is simpler to learn, and at $60–90 profit per bracelet, a $1,249 machine is a shorter break-even at lower volume. The question to answer honestly: what does my metal menu look like, and do I already have the volume to justify the difference?
The buying-twice math
Operators commonly report outgrowing the Zapp when they add heavier sterling or a high-volume booking calendar. If that growth is likely in the first year, the Zapp and then the mPulse is a more expensive path than starting with the mPulse. At $1,249 + $3,199, the sequential path costs $4,448 before the used-Zapp resale. The mPulse alone is $3,199.
The Zapp is still the right first machine if: fine chain is the plan, the business model is unproven, and capital preservation matters. But “I’ll upgrade later” is worth pricing out before you commit.
The middle path: Zapp Plus 2
Before the verdict: the Zapp Plus 2 (from $1,699) is worth naming here. It reaches the same full 1–30 joule range as the mPulse via a lock-in digital dial and is the lightest Sunstone at 1.9 lbs. If you want the mPulse’s joule range without the touchscreen price, the Zapp Plus 2 is the value answer. The mPulse earns its premium over the Plus 2 through the 0.5-joule fine steps below 15 joules, the touchscreen interface, and the Tru-Fire system, features that matter most at sustained high volume across multiple metals in a single day.
The verdict
Buy the Zapp if your first season is fine gold-filled and silver chain, you want name-brand support at the lowest Sunstone price, and your menu is not growing into 20 gauge rings in the near term. The 3–10 joule range does that job, and the $1,249 entry point has a fast break-even at weekend-market volume.
Buy the Orion mPulse if you weld heavier-gauge rings, you already have salon foot traffic or confirmed group-event bookings, you want the touchscreen speed and fine joule control for a full day of mixed metals, or the buying-twice math puts you here anyway.
Either way, put the price against your own booking rate before you spend. Operators who price correctly report $60–90 profit per bracelet after chain and clasp cost; both machines are a countable number of events, not a leap of faith.

What is the main difference between the Zapp and the Orion mPulse?
The Zapp delivers 3–10 joules on a dial for $1,249: the right range for fine chain. The Orion mPulse covers 1–30 joules with 0.5-joule fine steps below 15 joules, a touchscreen, and Tru-Fire Technology, from $3,199. The gap is headroom and interface, not just price: Sunstone's jump ring chart marks 20 gauge gold-filled, silver and 14K white gold as MAX POWER with multiple welds on the Zapp, while its mPulse 2.0 column lists 9 joules or less for every ring.
Is the Orion mPulse worth $1,950 more than the Zapp?
For an operator who already has salon foot traffic or event volume across mixed metals, usually yes. At $60–90 profit per bracelet, the mPulse price premium pays back in a countable number of appointments, and you avoid the cost of buying again when volume or heavier rings outgrow the Zapp. For a first-season operator welding mostly fine chain, the Zapp is more likely to pay back first.
Where does the Zapp Plus 2 fit between them?
The Zapp Plus 2 (from $1,699) is the middle answer worth naming: it reaches the full 1–30 joule range on a digital lock-in dial and is the lightest Sunstone at 1.9 lbs. If you want the mPulse range without the touchscreen premium, the Zapp Plus 2 is the value pick.
Do both machines carry the same warranty and support?
Yes. Both are Made in the USA, backed by a 3-year manufacturer warranty and US-based customer service. The mPulse additionally offers an optional Sunstone Circle plan that can extend coverage further. The core support that matters when a weld fails at an event is the same on both.
Can the Zapp weld sterling silver?
Yes, at most gauges. Sunstone's jump ring chart lists silver on the Zapp at LOWEST POWER for 26 gauge, 5 joules for 24 gauge and 7 joules with multiple welds for 22 gauge, while 20 gauge silver takes MAX POWER with multiple welds. The chart says silver, not sterling. Heavier silver rings are where a wider-range machine like the Zapp Plus 2 or mPulse earns its keep.
