Weller ETSL 0.4 mm Conical 43.5 mm Soldering Iron Tip for use with LR20, LR21 (old generation), WEP70

This soldering iron tip is a conical replacement tip intended for precision soldering and compatible with selected handheld and bench stations. It is designed to provide a fine contact point for detailed electronic work and integrates with legacy and current Weller-compatible equipment used in repair and assembly environments.

• Conical tip shape delivers accurate heat transfer for small joints
• Fine 0.4mm point enables precise component contact and control
• ET tip family design supports consistent thermal performance
• UPC approval indicates adherence to recognised product standards
• Compatible with multiple tool platforms for flexible inventory use

• Suitable for precision electronics soldering and rework
• Ideal for delicate component lead soldering tasks
• Used with LR20 station replacements in maintenance shops
• Can be used on older LR21 generation tools during upgrades
• Used for WEP70 station tip swaps in production lines

The tip is compatible with specific LR20 models, older LR21 generation units and selected WEP70 stations, enabling use across these tool types.

The narrow 0.4mm point concentrates thermal energy at the joint, reducing heat spread to surrounding components and improving precision.

The conical profile and ET-style construction provide a predictable contact geometry that maintains consistent wetting behaviour during repeated cycles.

It is intended for precision electronics tasks where a fine point and controlled heat delivery are required rather than broad soldering work.
