Pulse Jewelry Spot Welder | Gold Silver Platinum Welding Machine
This bench-top pulse spot welder is designed for fine jewelry welding tasks on gold, silver, platinum and steel. With dual coarse and fine power adjustment, a foot-switch trigger, and a confirmed 0.4-1.0 mm welding range, it gives the operator precise control for delicate repair and making work at the bench.
The front panel provides two adjustment knobs, a power switch and connection points for the welding accessories. The operator connects the welding clip and tungsten needle holder, sets the output level, positions the workpiece near the tungsten needle and triggers each short weld pulse with the foot switch — keeping both hands free to hold and align the piece.
Voltage Selection Guide
This welder is available in two voltage versions. Select the correct version for your local power supply before purchase.
- 110V — North America, Japan, and other 110V regions
- 220V — Europe, Australia, Asia, and other 220V regions
Best For / Not For
| Best For | Not For |
|---|---|
| Fine jewelry wire and small connection points within 0.4-1.0 mm | Large metal fabrication, heavy structural welding or thick parts outside the confirmed range |
| Gold, silver, platinum and steel jewelry repair tasks | Users expecting automatic welding without manual alignment and parameter testing |
| Jewelry benches, repair counters and small studio workstations | Workflows without proper eye protection or stable workpiece holding |
| Ring mouths, small clasps, fine wire and small jewelry components | Continuous foot-switch operation or long-duration arc holding |
| Operators who can test settings and adjust by material and joint size | Applications requiring certified weld performance or guaranteed appearance results |

Pro Tips
- Test the output on compatible scrap material before welding a finished jewelry piece.
- Start with a lower setting and increase gradually using the coarse and fine controls.
- Keep the tungsten needle clean and correctly shaped for more consistent discharge behaviour.
- Clean the joint area before welding to reduce contamination at the weld point.
- Use appropriate eye protection and release the foot switch immediately after each short weld pulse.
Frequently Asked Questions
What materials can this spot welder be used on?
The confirmed compatible materials are gold, silver, platinum and steel jewelry components.
What wire or joint size is it intended for?
The confirmed welding range is 0.4-1.0 mm, making it most suitable for fine jewelry work rather than heavy parts.
Does it include a foot switch?
Yes. The package contents include one foot switch for hands-free pulse triggering.
How do the two front knobs work?
The machine uses coarse and fine power adjustment. Use the coarse knob for broad output changes and the fine knob for smaller setting adjustments.
Can I hold the foot switch down continuously?
No. The foot switch should be pressed briefly and released immediately after each weld pulse. Continuous pressing can damage internal circuits.
What should I do if the weld result is inconsistent or the machine is not performing as expected?
First check that the tungsten needle is clean and correctly shaped, and that the joint area is free of contamination. Verify the accessory connections are secure and test on scrap material at a lower setting.
