Weller Soldering Iron Tip, 43.5mm Tip Length, 0.4mm Tip Width - 4ETSL-1
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.
Features and Benefits:
• 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
• 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
Applications
• 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
• 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
Will it fit a variety of soldering stations?
The tip is compatible with specific LR20 models, older LR21 generation units and selected WEP70 stations, enabling use across these tool types.
How does the tip affect fine soldering performance?
The narrow 0.4mm point concentrates thermal energy at the joint, reducing heat spread to surrounding components and improving precision.
What design aspect ensures repeatable results?
The conical profile and ET-style construction provide a predictable contact geometry that maintains consistent wetting behaviour during repeated cycles.
Is this tip intended for general-purpose or specialised tasks?
It is intended for precision electronics tasks where a fine point and controlled heat delivery are required rather than broad soldering work.
