Weller Soldering Iron Tip, 34.5mm Tip Length, 3.2mm Tip Width - 4ETC-1


This soldering iron tip is a chisel‑shaped replacement designed for precision heat transfer in professional soldering stations. It fits older handheld and bench units and is intended for tasks requiring controlled solder distribution and repeatable joint formation in industrial and laboratory environments.

Features and Benefits:


• Chisel profile improves solder wetting and joint coverage
• 3.2mm width delivers consistent thermal contact area
• 34.5mm length offers extended reach in confined assemblies
• UPC approval ensures adherence to recognised safety marking
• Compatible with legacy tool interfaces for straightforward swaps

Applications


• Suitable for repetitive through‑hole assembly in electronics production
• Ideal for maintenance of automation control boards and connectors
• Used with WEP70‑compatible soldering stations in repair benches
• Can be used for refurbishment of older LR20 handpieces in workshops
• Used for component replacement on legacy LR21 equipment

How does the tip affect heat delivery during precision soldering?


The chisel geometry concentrates thermal mass along a broad edge, enabling even heat transfer across joint surfaces while maintaining temperature stability under typical bench soldering loads.

Will it fit different tool handles without modification?


It is intended for direct insertion into compatible older‑generation handpieces and bench irons constructed to the same interface, allowing replacement without adaptor parts when matched correctly.

What maintenance practice preserves performance?


Regular cleaning of oxidised residues and periodic re‑tinning after use reduces thermal resistance and prolongs effective thermal conduction.

How does the tip assist in working within tight component arrays?


The combination of its elongated profile and flat working face permits access between closely spaced parts while still presenting sufficient contact area for reliable solder flow.
