Weller Soldering Iron Tip, 34.5mm Tip Length, 1.6mm Tip Width - 4ETR -1
This soldering iron tip is a replaceable screwdriver-style tip designed for use with compatible Weller soldering tools. It functions as the working end for thermal soldering tasks, providing a shaped contact point for transferring heat and solder to joints. The tip is intended for integration into handheld soldering stations and irons in professional and workshop settings where interchangeability and specific tip geometry are required.
Features and Benefits:
• Screwdriver-shaped tip delivers broad contact for confident solder flow
• UPC-approved component ensures consistent manufacturing traceability
• Compatible with legacy and current handheld units for flexible replacement
• Hardened construction supports repeated thermal cycling without distortion
• Narrow width provides precise orientation for through-hole and leaded work

• Narrow width provides precise orientation for through-hole and leaded work
Applications
• Suitable for replacing worn tips on LR20 units
• Used with WEP70 irons for routine electronics assembly
• Ideal for retrofitting older LR21 equipment in service workshops
• Can be used for general-purpose leaded solder joints requiring broad contact

Which tools will accept this tip mechanically and thermally?
It fits designated compatible Weller handles and stations that use the same tip interface, allowing correct thermal transfer and secure mounting during soldering.
How does the screwdriver shape affect soldering technique?
The flattened, blade-like geometry increases contact area, improving heat distribution for filling larger leaded joints and aiding solder wetting across straighter edges.
What should be considered when replacing an old tip with this one?
Ensure the handle or iron uses the matching mounting system and that the tip is seated fully to maintain thermal conduction and mechanical stability.
How does interchangeability benefit workshop maintenance?
Using a replaceable tip simplifies upkeep by reducing downtime
technicians can swap worn tips quickly without replacing the entire iron, preserving tool investment.
