Heat source for heat shrink

  1. What do people here use for heat shrink tubing?

    I'm tired of using matches, and a butane pencil torch seems like overkill.

    I run the tip of my soldering iron over it if it small - otherwise I use a
    heat gun
  3. I use a heat gun..

    an electric heat gun.
    Harbor Freight sells them VERY inexpensively.
    I imagine some better hair dryers would also work.

    I find one of those long nozzled butane lighters used to light outdoor
    BBQ's etc. works well in most situations . Big flame to cover a good
    size area, but not too hot.

    I have one of those HF guns. Also works fine but of course you have to
    plug it in somewhere ;-)

  7. Dan spake thus:
    I thought about a heat gun; we're talking about those things that are
    basically glorified blow dryers, right? Isn't that a little much just to
    heat a little bitty piece of tubing? Are there any "mini heat guns"
    available to heat smaller things?

    Not that I'm aware of, the size doesn't matter, that's exactly what
    they're designed for amoung other things, it works better than anything
    else I've ever tried.

    I think the real heat guns are considerably hotter than a hair dryer.
    They're the best thing in most circumstances. Someone suggested the tip
    of a soldering iron, which works, but I find the barrel works better.
    The tip is a tad *too* hot sometimes.

    I use a heat gun that was designed for heat shrik tubing.

    I use a Black and Decker two heat paint stripper gun for the big stuff, and
    a butane flameless mini heatgun, for the small stuff, and have used both for
    years. The butane gun is actually a pencil gas torch, of the type that often
    has a catalytic soldering tip available for it. The heatgun accessory, is
    basically the same, in that the gas passes over a platinum wire catalyser,
    which glows red hot, and then exits as a stream of hot gas, from the nozzle.
    Intensity of the jet, and temperature, can both be controlled by the setting
    of the gas valve. It refills from a normal can of butane cigarette lighter
    gas. There are dedicated heatgun only tools as well. Look at

    for examples

  13. Cheapest way is to get a dual heat setting hot air paint stripper gun from
    a DIY shed. They're often on offer for a very small sum. Only use on low
    power setting. Don't get a single heat setting one as they're rather too

    The pro types are expensive. They're smaller so might be better if using
    heat shrink inside an amp etc and they don't produce so much heat.

    But for cables etc, a paint stripper type on 1Kw or less output is fine.
    Some hairdriers can also be used if they have a nozzle to direct the

    I have an Ungar. You can probably buy one for $300. I also have a Weller station
    for about $900. The Ungar has been wonderfull and I bought it over 20 years ago for about $80.

    Ahh, Electronix Express has two models probably cheaper than anybody but
    Harbor Freight, but these are for heat shrink.

    A heat gun is the ideal choice and is quite inexpensive. But for quick
    jobs or when I'm away from the bench I often use a butane cigarette
    lighter (then give the heatshrunk a quick wipe to remove the soot).

  17. I think they are basically a blow dryer with the element closer to the
    end of the blower tube...blow dryers have pretty-well maxed out the
    wattage of a 120 VAC circuit.

  18. I think the major difference between a hair dryer and a heat gun is
    airflow.. A heat gun doesn't move nearly the volume of air that a hair dryer

    Not a butane pencil torch (sounds like a blowlamp!) but I use the side
    "exhaust port" of an Oryx Portasol butane soldering iron. Usually because
    I can't be bothered to change the (hot) soldering iron tip for the proper
    hot air blower attachment! In either case, you get a good stream of hot
    air, with no flame. Does just fine for small sleeving, might take a while
    for larger stuff though!

    The Ungar has a narrow opening and has different tips to control the flow
    some more. Its about 600 watts. Will melt solder at about 600 to 700 degrees.
