Standard Wiring Pencil (QSE) RRP-103

£12.55

This Standard Wiring Pencil (QSE) RRP-103, without Brake, is preloaded with a Solderable Enamel Wire Bobbin or wire spool.

The original Roadrunner® Wiring Pencil prototyping wiring tool, is well balanced and easy to handle, with a long-life stainless-steel tip for high speed accurate wiring, even in the most confined areas.

Wire feed tension is varied by gently adjusting the bobbin supports or adjusting the angle of the device during the wiring process. A full, ready to use wire spool, is supplied with each pencil.

This wiring tool, is recommended for: beginners or advanced students, technicians, engineers or hobbyists for the assembly and wiring of Dual In Line logic and microprocessor circuits or discrete electronic circuits using the Roadrunner Rapid Wiring System, Surface Mount Technology (SMT) and the wiring of Surface Mount Devices (SMD’s); for end of line or Field Service for PCB or PWB track repair, rework, shorting links or modifications.

The coloured Solderable Enamel Wire (QSE) bobbins are interchangeable with the TCW Wiring Pencils (RRP-104 and RRP-124).

Frequently Asked Questions

What is the RRP-103 Standard Wiring Pencil (QSE)?
The RRP-103 is a wiring pencil preloaded with a bobbin of solderable enamel wire (QSE), featuring a stainless-steel tip for high-speed, precise wiring without a built-in brake.

How do I control wire tension on the RRP-103?
Adjust the bobbin support friction or change the pencil angle during use to vary feed tension, ensuring a smooth and consistent wire flow.

What applications is the RRP-103 suited for?
Ideal for wiring DIL logic and microprocessor circuits, discrete electronics, SMT/SMD assemblies, PCB track repairs, shorting links, and field-service modifications using the Roadrunner Rapid Wiring System.

Which QSE bobbins are compatible and how are they replaced?
Compatible bobbins include 0.15 mm (RRP-C-105, RRP-G-105, RRP-P-105, RRP-V-105, RRP-A-105) and 0.19 mm (RRW-C-105, RRW-G-105, RRW-P-105, RRW-V-105, RRW-A-105). Unscrew the cap, swap the bobbin, and reassemble.

Are there any safety considerations when using solderable enamel wire?
Yes. The insulation is burnt off at 400–430 °C, releasing toxic toluene diisocyanate vapor. Always ventilate or use fume extraction, wear eye protection, and follow safe soldering practices.
