How to shrink heat shrink tubing?
in [Repair]
|
From: Geoffrey S. Mendelson on 10 May 2010 12:24 I've recently started doing electronic repairs (mostly wiring) and need to shrink heat shrink tubing. A long time ago I bought a heat gun used for removing paint and used that. It was 120 volt, so I left it when I moved here. I've never had much luck (or is it patience?) shrinking it by holding it over a soldering iron tip. Using a flame, like a cigarette or stove lighter ends up with burnt plastic. :-) Is there such a thing as a small heat shrink tube shrinker that does not toast the things around it? The largest thing I need to shrink over is about 1/2 an inch most of them are small (20awg or less) wires. Thanks in advance, Geoff. -- Geoffrey S.

Wrap the tip of (old) soldering iron with some plumber's PTFE tape and then apply the iron directly to the tubing or use a replacment tip , so adapted. -- Diverse Devices, Southampton, England electronic hints and repair briefs , schematics/manuals list on http://diverse.4mg.com/index.htm

We use Weller's #6966C, which is a small, lightweight gun that comes with an assortment of heat focusing attachments. There are many, many heat guns available in a huge array of styles and sizes, check your solder and tools supplier's catalog.

DuPont studies show that the Teflon offgases toxic particulates at 446°F. At 680°F Teflon pans release at least six toxic gases, including two carcinogens, two global pollutants, and MFA, a chemical lethal to humans at low doses >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> > -- > Diverse Devices, Southampton, England > electronic hints and repair briefs , schematics/manuals list onhttp://diverse.4mg.com/index.htm- Hide quoted text - > > - Show quoted text - |
