my tests on a computer motherboard I found that small
resistors and components could be individually removed
quite easily with the Cold Heat tool. However, the use
of solder wick to remove small IC chips or components
did not work. The wick appeared to be too much of a heat
sink for the Cold Heat tool. Slightly larger components
also could not be removed. I tinned some small speaker
wires, but found that soldering and splicing wires is
questionable depending on the size of the wire. A PC
board from Radio Shack— the type used in building
electronic kits—and a couple of quarter watt resistors
were also used in some of my testing. The resistors soldered
to the board contacts quickly and with good conductivity.
marketing materials, TV ads and the infomercials all
emphasize that the working tip cools instantly. Some
of the advertising shows people touching the tip immediately
after a soldering operation. In reality it does cool
quickly, but not exactly instantly. If you've had the
iron hot for a couple of minutes while soldering wires
or trying to desolder a medium or large sized component,
don't touch the tip immediately. It will still be very
hot depending on how long you've been powering the unit.
Power and heat are power and heat even though the tip
does cool incredibly fast compared to traditional soldering
guns or irons.
of us who have soldered for years using either the big,
powerful Weller Soldering Station or similar temperature
controlled irons know that power is the big thing. It
takes power to generate enough heat to melt solder, especially
when connecting or desoldering large components and when
using solder wick. So it doesn't take a genius to figure
out that the four AA batteries powering the Cold Heat
tool can only supply a comparatively limited amount of
energy (however hot the tip gets). Consequently, the
Cold Heat tool is good only for small tasks such as those
suggested by the manufacturer.
works. Although the usage list is somewhat limited, it
gets the job done. The Cold Heat tool is also portable
and wireless, will fit into your tool box and carry easily,
and it certainly cools quickly, all of which are definite
pluses especially for quick, small, emergency repairs.
Besides the tasks listed above, the Cold Heat tool can
be used on remote controlled (RC) cars, to repair or
make jewelry, on fishing gear, car stereo wiring and
repair, repairs to amplifiers, radios, computers, audio
cables and building Christmas ornaments.
