soldering, welding or cutting when using these
products can contain chemicals known to the
State of California to cause cancer, birth defects
or other reproductive harm. Some examples of
these chemicals are:
• lead from lead-based soldering wire,
• fl ame retardants from fl ame resistant insula-
tion Styrofoam.
Your risk from these exposures varies, depen-
ding on how often you do this type of work. To
reduce your exposure to these chemicals: work
in a well-ventilated area, and work with appro-
ved safety equipment. For more information go

1. The device is only to be used, installed and
serviced by personnel familiar with it.
2. It must not be used by children.
3. Keep the device and its cable away from
the reach of children.
4. Children must not be allowed to play with
the device.
5. WARNING: When not in use, the tool must
be on its supporting stand.
6. Take care when using the device at locations
where combustible materials are on hand.
7. When working, constantly guide the device
through the work piece!
8. Do not use it in an explosive environment.
9. Bear in mind that heat can be directed to
combustible materials beyond one's fi eld of
vision.
10. Place the device on its supporting stand
after use and allow to cool before storing.
11. Do not leave the device unattended when
switched on.
12. The manufacturer, his after-sales service or
those similarly qualifi ed are to replace any
damaged cable so as to avoid any hazards.
13. Always disconnect the device from the po-
Some fumes or
gases created by
wer supply when left unattended and befo-
re it is installed, disassembled or cleaned.
14. Note that the wire is still warm after use!
15. Warning: Incorrect usage can result in injuries.
16. Only use the supplied heating wires and
original replacement wire
17. Use only in dry locations.
Note: Electrical appliances should not be used
uninterruptedly for more than 15 minutes. Gi-
ven overloading, the power unit shuts itself
down (pull out the mains plug). Allow the power
unit to cool for some 3 to 5 minutes. It is then
ready to be operated again.
1 Description of the device
With its hot wire, Thermocut 650 cuts through
styrofoam, Styrodur and many other aerated
plastics. The cutting wire technique is superior
to all other techniques - and particularly the pu-
rely mechanical ones - such as cutting off with
knives and the like. It provides a high degree
of fl exibility and an optimum cut for a host of
applications.
Wire of only a 0.2 mm thickness is electrically
heated to a maximum 350°C for cutting off
purposes. For this, 40 V is provided by a switch-
mode power unit. This voltage is absolutely
harmless from the safety angle and together
with the electronically controlled power supply of
the cutting wire ensures a universal non-critical
cutting temperature. A practical rotary button on
the ergonomically designed housing is for pre-
selecting the temperature as required conditio-
nal upon the material and cutting speed.
During cutting, the mechanical tension of the
cutting wire - irrespective of its temperature - is
kept constantly by an moveable and spring-loa-
ded clamping bar. This effectively compensates
for a thermally-induced expansion of the wire
during the work. The clamping bar is adjustable
over a wire length of 400 to 650 mm. The ma-
ximum cutting depth is 200 mm. The device is
thus more than adequately dimensioned for lar-
