Weller PTO8 (425°C) 0.8 mm Round 44 mm Soldering Iron Tip for use with TCP (series (old generation)

This soldering iron tip is a replacement component designed for precision soldering tasks within older TCP handheld irons. It functions as a round-profile tip for detailed work, compatible with legacy TCP equipment and intended for operations requiring a fine contact point and consistent heat delivery.

• Round profile ensures precise wetting and controlled solder flow
• Tip width 0.8mm provides fine-point accuracy for small joints
• Operating capability up to 425°C supports high-temperature soldering
• Length 44mm offers extended reach into confined assemblies
• Compatible form factor for older TCP handpieces enables easy swap-out

• Suitable for delicate component soldering on compact boards
• Ideal for rework of fine-pitch connectors and leads
• Used with legacy TCP irons in repair workshops
• Can be used for small-scale production soldering tasks
• Appropriate for precision electronics maintenance and modification

The round geometry concentrates heat at a small contact area, improving solder transfer and minimising thermal spread to adjacent components.

Ensure the replacement matches the original contact profile and length to maintain heat transfer characteristics and fit the ferrule correctly.

A maximum operating temperature of 425°C permits use with common leaded and lead‑free solders, though flux selection and dwell time must be adjusted for alloy melting points.

Regular tinning, controlled temperature use, and avoiding excessive mechanical abrasion will extend functional life and maintain thermal performance.
