Product Details

Weller Straight Conical Soldering Iron Tip

The 4ETSL-1 is a soldering iron tip which can be used with the WEP 70 (RS 173-7304) and the LR 21 (RS 162-6518) soldering iron. These tips provide optimal performance and the micropoint tip is suitable for delicate fine electronic work which other tips are unable to do.

Features and Benefits:

  • ET tips for use with WEP 70 and LR 21 soldering iron

  • Designed for universal soldering jobs

  • Durability and long-life

  • Affordable

  • Easy tip change – no additional tool needed

  • High quality performance

  • Width: 0.3 mm

  • Length: 43.5 mm

  • Tip shape: long conical tip

Typical Applications:

Soldering is the process used to build a soldering connection by using the heated tip of a soldering iron to melt soldering wire. The soldering tips are available in many different sizes and tip shapes, dependant on the application they are being used for. They are used to melt solder wire to connect two elements or components together to create a permanent connection and are often utilised in an electronics or manufacturing capacity as they often need to be conductive. The process of soldering is most commonly used by:

  • DIY enthusiasts

  • Plumbers

  • Electricians

  • Vehicle technicians

Soldering is often used for:
  • General wiring applications

  • Electrical repair work at home, in factories or for vehicles

  • Audio systems

  • Cable assembling

  • Indoor lighting

  • Low-voltage wiring

  • PCBs

  • Radio-controlled

  • Repairs

  • Small appliances and engines


How long do soldering iron tips last for?

If high quality iron tips are used, they can last for years with the proper care and cleaning.
