The Best Soldering Iron for Stained Glass
Researched by Johnny Alto · last updated July 27, 2026
Short answer: The best soldering iron for stained glass is the Hakko FX601-02. The most-recommended iron for copper-foil stained glass. The main things to weigh are wattage, temperature control, tip, and weight & balance.
Hakko FX601-02
The most-recommended iron for copper-foil stained glass. It has an on-handle temperature dial (roughly 310 to 540°C), heats to working temperature fast, and makers consistently note it's noticeably lighter on the wrist than the old 100W irons. That matters a lot over a long soldering session.

Representative image.Ask in almost any stained-glass group and the same answer comes back: you want a temperature-controlled iron in the 80 to 100W range with a ¼-inch tip for copper-foil work. Here's the one that comes up more than any other, plus the classic heavy-duty alternative.
How do the best options for soldering iron for stained glass compare?
| Pick | Product | Why it makes the list |
|---|---|---|
| Top pick | Hakko FX601-02 | The most-recommended iron for copper-foil stained glass. |
| Heavy-duty classic | Weller 100W Iron | The long-time standard for large panels and long seams. Its heavy tip holds heat beautifully on big work. The trade-off is that it's less nimble for tiny, detailed foil lines, and heavier over time. |
What should you look for in soldering iron for stained glass?
A few things separate a good soldering iron for stained glass from a frustrating one: wattage, temperature control, tip, and weight & balance. Weigh these before you buy.
- Wattage: 80 to 200W. Below about 80W it struggles to keep up on foil seams.
- Temperature control: an adjustable iron lets you dial heat to the solder and the job.
- Tip: a ¼-inch tip suits most copper-foil and lead-came work; smaller tips for decorative detail.
- Weight & balance: you'll hold it for hours, so lighter, well-balanced irons win.
What are the best alternatives?
Weller 100W Iron
The long-time standard for large panels and long seams. Its heavy tip holds heat beautifully on big work. The trade-off is that it's less nimble for tiny, detailed foil lines, and heavier over time.
Bottom line: for most hobbyists and pros doing foil work, the temperature-controlled Hakko is the safe default; step up to a 100W-class iron only if you're regularly soldering big panels.
