Overview
A garage workbench or an electrical job site suits this Weller heavy duty iron, which plugs straight into the wall with no base station. The tip itself sets the working temperature, and closed-loop control holds it from running too hot.
High power and a simple plug-in design handle thick wires and large joints that small pencil irons struggle with. Temperature is fixed by the tip, so changing heat means changing tips.
Who it's for
Electricians, hobbyists and metalworkers soldering thick connectors and heavy parts. Electronics builders working on circuit boards need a smaller, adjustable station.
Pros and cons
- High power for large joints
- No base station needed
- Temperature limited by tip
- Fast heat up
- No temperature dial
- Bulky for circuit boards
- Other temperature tips not clearly included
Performance notes
The tip controls the maximum temperature through a closed loop, so the iron cannot drift above the tip's rating. The nichrome element recovers heat quickly between joints on heavy work.
