Antex
The XS25 is a 25W fixed-temperature pencil iron, made in the UK by Antex since the 1970s — the archetypal simple soldering iron most UK electronics hobbyists learn on.
Strengths
- No menus, no setup — plug in and it heats to a fixed working temperature
- UK-made with widely available replacement elements and tips
- 25W is enough for most light electronics and hobby soldering
Trade-offs
- Fixed temperature — no adjustment for delicate components or heavier joints
- No digital readout to confirm actual tip temperature
Verdict
A reliable, no-frills choice for light electronics work where you don't need adjustable temperature — it's been the default UK hobbyist iron for decades for a reason.
Antex XS25 wattage and temperature explained
The Antex XS25 wattage and temperature describe different parts of how the iron works. The 25W rating describes heating power, while ~370°C (fixed) describes the listed working temperature. A fixed temperature does not mean the tip stays at exactly that figure during every joint. The work draws heat away when the tip makes contact.
A larger joint can cool a tip faster than a small component lead. Good contact and a tinned surface help heat move into the joint. If solder takes too long to flow, check those first. Avoid holding the iron on a PCB pad for a long period, because prolonged heating can damage the pad even with a lower-wattage iron.
Antex XS25 price and replacement tip checks
The Antex XS25 has a typical UK street price of ~£25–30, with replacement tip compatibility needing a separate check. The price is a guide rather than a confirmed offer from a named stockist. The specifications this site has verified do not give current retailer stock.
For a replacement tip, use the exact Antex XS25 model name and ask the seller to confirm fit. The specifications this site has verified do not supply a tip series or part number. Choose a working shape that contacts the joint without touching nearby components. Check what comes with the iron offer, as a price for the iron alone does not confirm a complete bench setup.
