Weller Soldering Iron Tip, 34.5mm Tip Length, 1.6mm Tip Width - 4ETA-1
This soldering iron tip is a chisel-shaped replacement component designed for professional soldering tools. It provides a defined contact profile for controlled heat transfer in assembly and repair tasks across industrial environments. The tip is intended to be fitted to compatible soldering handles used in routine and precision joining operations.
Features and Benefits:
• Chisel geometry delivers accurate wetting and solder flow
• UPC approval ensures standardised manufacturing traceability
• Compatible with specified older handpieces to extend service life
• Robust construction supports repeated thermal cycling
• Narrow working edge aids fine joint access and control

Which handles will accept this tip?
It fits specific WEP70 and legacy LR20 and LR21 soldering handles that use the matching connection interface.
How does the tip profile affect soldering technique?
The chisel form provides a flat contact for even heat distribution and improved solder bridging on leaded and surface-mounted joints.
What material behaviour should be expected under repeated use?
The tip is manufactured to tolerate normal thermal cycling for routine service life while maintaining shape for consistent performance.
How long is the working portion for access into assemblies?
The usable length of the tip measures 34.5mm which allows reach into recessed areas without impeding handling.
