FULL FLEXIBILITY
FOR PORTABLE HEAT SHRINKING
HOT TIPS FOR PERFECT HEAT SHRINKING
Start the shrinking process in the middle of the tube.
From there, move outwards to one end and then again
from the middle to the other end. This way you avoid
trapping air under the tubing.
Shrink tubing also shrinks in the longitudinal direction,
i.e. it becomes shorter overall when shrunk. You should
take this shrinkage rate into account when cutting
sections.
If the object to be wrapped is heat conductive, make
sure to preheat the object to avoid “cold spots“. This
will ensure a tight and smooth fit.
When cutting heat shrink tubing to the desired length,
take special care to cut the ends smoothly. Poorly cut
and irregular ends can cause heat shrink tubing to tear
during shrinking.
When selecting the tubing size, it is important to follow
the 80:20 rule. Select the size so that it can shrink by at
least 20% and at most 80%.
DON‘T FORGET
With the brand new CHG900 cordless heat gun, shrinking
on the go is a joy.
FASTER RESULTS WITH THE CORDLESS ALL-ROUNDER
The CHG900 is a gas hot air blower designed for shrink
applications where no power source is available or full
mobility is desired. It is also suitable for soft soldering,
plastic moulding or defrosting.
The handy tool generates instant, adjustable heat from
190 °C up to 900 °C and produces no open flame. It provides
1.5 hours of operation per cartridge, even at low
air temperatures around -8 °C. Only after 60 minutes of
continuous operation is a short rest period of 15 minutes
required to allow the internal components to cool
down and avoid damage.
No battery-powered hot air tool offers this much autonomy
for heat shrinking. Its operating time depends
on the number of shrinking processes, the shrinking
temperature and the shrinking time.
But with a full gas cartridge, the CHG900 works reliably
for about 90 minutes regardless of the number, temperature
and duration of the shrinkages. The charging
time of a battery-powered device usually takes longer
than the cooling time of the CHG900.
LIGHT AND HANDY
The CHG900 weighs only 555 g including a full P445 gas
cartridge. This makes it one of the lightest hot air guns
on the market. The gas cartridges, as well as critical
spare parts such as the piezo ignition and the gas nozzle,
can be replaced quickly and without additional tools.
The empty cartridges are also fully recyclable.
The CHG900 can be placed securely in a stable position
for horizontal or vertical heat flows. The integrated
stand frees up both hands for maximum control when
shrinking.
During shrinking, always ensure that the workplace is
well ventilated and that you wear personal protective
equipment such as gloves and safety goggles.
Use a heat gun that has a secure stand on the workbench
so that you can work on the shrink application
with both hands.
