Weller W100PG Soldering Iron
A classic 100-watt iron that regulates temperature through its compatible tips.
The W100PG remains popular for stained glass because it is uncomplicated and holds a working temperature through the tip itself. Once the right CT6 tip is installed, there is no dial to bump and very little to learn.
Reasons to choose it
- Simple high-heat foil work
- 100 W output
- CT6 tip family
Consider before buying
- Temperature changes need another tip
- Confirm included tip
- Choose the HAKKO FX-601 if you expect to adjust temperature often or want a lighter published handpiece.

What ownership is actually like
Changing temperature means changing tips, which is slower than turning a dial but also highly repeatable. Let the iron recover in a proper stand between long seams and keep the working face of the tip clean and tinned.
Who it suits
This is a strong shortlist candidate for simple high-heat foil work. The useful question is whether that describes most of your work, not merely one future project.
When another tool makes more sense
Choose the HAKKO FX-601 if you expect to adjust temperature often or want a lighter published handpiece.
