The Zapp Plus 2 Pulse Arc Welder is a compact jewelry welder from Sunstone Welders, designed for permanent jewelry and small repairs rather than for ordinary stick, MIG or TIG welding. It is worth considering if you want to start a permanent jewelry service or close jump rings quickly. Skip it for any steel fabrication.

What It Does and Who It Suits
A pulse arc welder releases a short burst of energy at a tiny contact point to fuse the metal. That makes it suitable for closing jump rings and joining chain links in precious metals without large heat spread, which is the basis of permanent jewelry.
It suits jewelers, boutique owners and hobbyists who want a compact tool they can take to events and pop-ups. It does not suit anyone who needs to weld steel, thick sections or brackets. For those, see the machine reviews linked below.
How to Check It Fits Your Use
- Metals: confirm the metals you plan to weld (gold-filled, sterling silver, solid gold, platinum) are listed as compatible by the maker. Settings differ for each.
- Argon: decide if you want argon. You will need a cylinder, regulator and flow meter if so.
- Optics: check what kind of viewing or magnification suits you. Many jewelers use a scope or an auto-darkening lens, usually sold separately.
- Training: see what training is included with the machine and what costs extra.
- Power: check the power requirements and any permits or business rules for operating at events.

Basic Usage and Safety Tips
- Prepare the chain, clasp and jump ring. Make sure all pieces are clean and the joint is aligned.
- Set the energy dial low and test on scrap metal of the same type.
- Position the electrode or stylus at the joint and fire a weld, increasing energy in small steps.
- Inspect the weld under magnification and repeat if the joint is not fully closed.
- Follow the manufacturer’s guidance for protecting skin when welding on a client.
Wear eye protection suited to the bright flash, keep the area clear of flammables, and secure any argon cylinder.

Frequently Asked Questions
Is the Zapp Plus 2 a stick welder?
No. It is a pulse arc welder designed for jewelry, especially permanent jewelry such as chain bracelets and anklets. It delivers short, controlled bursts of energy to tiny joints, not the continuous current used by stick, MIG or TIG machines on structural metal.
Do I need argon gas with the Zapp Plus 2?
The listing describes optional argon shielding, which reduces oxidation and can give cleaner, brighter welds. Whether you need it depends on the metal and the finish you want. If you add argon, secure the cylinder, use a regulator and flow meter, and follow the manufacturer’s setup instructions.
Can a beginner learn permanent jewelry welding on it?
The listing highlights a single dial and training resources such as a QR code, and Sunstone offers training options. Even so, plan on practice time with scrap chain and jump rings, and learn safe handling around client skin and jewelry before you offer welding to customers.
What safety gear should I use?
Wear appropriate eye protection or the optics the manufacturer recommends, keep flammable material away, and never weld directly on a client’s skin without following the maker’s instructions and protective methods. Ventilate the work area and keep any argon cylinder secured upright.
Verdict
The Zapp Plus 2 is a niche tool that makes sense if permanent jewelry is your goal. Confirm the specifications, compatible metals and any add-on costs with the seller and plan for practice and training.
