PHYHOO Jewelry Spot Welder | CNC Argon Arc TIG 50A–150A

Professional CNC argon arc TIG spot welder engineered for jewelry repair shops and dental labs — delivering laser-quality welds at a fraction of the cost, with 50A–150A adjustable power and 5 factory metal presets.

Key Selling Points

• Pulse Dense Arc Technology — rivals laser welding precision at a fraction of the investment, delivering clean and invisible welds on delicate jewelry pieces
• 50A–150A Adjustable Welding Current — precise power control for every metal type and thickness, from ultra-thin gold foil to 5 mm (0.2") stock
• 5 Factory Metal Presets — optimized programs for gold, silver, platinum, titanium, and cobalt-chromium, reducing setup time and operator error
• Auto Safety Shutoff — powers down automatically after 5 minutes of inactivity, protecting the machine and reducing energy consumption
• Dual Voltage 110V and 220V — compatible with workshops worldwide, no external converter required
• Compact Bench Footprint — 42 x 30 x 26 cm (16.5" x 11.8" x 10.2"), fits any jeweler's workbench without sacrificing workspace

About This Product

The PHYHOO CNC Argon Arc TIG Spot Welder uses pulse dense arc technology to produce concentrated, high-energy welds that minimize heat distortion on precious metals. The argon gas shielding prevents oxidation during welding, resulting in clean joints that require minimal post-weld finishing — critical for fine jewelry repair and dental prosthetics work.

Designed for both professional jewelers and experienced hobbyists, the machine offers independent control over penetration depth and solder joint diameter. The low-noise operation and stable arc make it suitable for extended work sessions in small studio environments.

Pro Tips

• Set argon flow to 3–5 L/min for most precious metal work. Higher flow wastes gas without improving weld quality; lower flow risks oxidation on platinum and gold.
• Start with the factory preset for your metal type and adjust current in 10A increments. Test on scrap material of the same thickness before working on the actual piece.
• Shorten pulse duration (3–8 ms) for thin stock under 1 mm (0.04") to prevent burn-through. Increase to 15–25 ms for thicker sections above 3 mm (0.12").
• Replace the tungsten needle when the tip becomes rounded or contaminated. A sharp, clean tip produces a focused arc and cleaner weld joints. Keep spare needles on hand for uninterrupted workflow.
• Clean the welding area with isopropyl alcohol before each session to remove oils, flux residue, and oxidation. Contaminated surfaces cause arc instability and weak weld joints.

Frequently Asked Questions

Is this machine the same as a laser welder?
No. This is a pulse argon arc TIG spot welder, not a laser welder. It uses pulse dense arc technology to achieve similar weld quality on precious metals at a significantly lower cost. It is not suitable for applications that specifically require a laser welder's non-contact operation.

Does it require argon gas to operate?
Argon gas is required for oxidation-free welding on precious metals such as gold, silver, and platinum. The machine can operate without argon for general-purpose applications, but weld quality on precious metals will be significantly reduced. Argon gas and regulator are not included and must be sourced locally.

Can it weld stainless steel or iron?
No. This machine is optimized for non-ferrous precious metals and dental alloys including gold, silver, platinum, titanium, and cobalt-chromium. It is not designed for ferrous metals such as steel, iron, or stainless steel.

What is the maximum material thickness it can weld?
The maximum welding thickness is 5 mm (0.2"). For best results on jewelry repair, most applications fall within 0.3–2 mm (0.01"–0.08"), where the machine delivers the most precise and controllable welds.

Is the machine compatible with both 110V and 220V power supplies?
Yes. The machine supports dual voltage (110V and 220V, 50/60 Hz) and can be used in workshops worldwide without an external voltage converter. Select the correct voltage setting before first use.
