# Adjust the temperature with the regulator 2. The table on the front of the device serves as a guide. The best way to find the ideal temperature is to try different temperatures yourself. For simple, straightforward cuts you use a high temperature, for complicated shapes a lower temperature.

# Now move the workpiece through the wire with a light pressure and even speed. Be aware that too high pressure in the direction of the cut when cutting complicated shapes will tend to bend the wire.

Note:
Note: It is normal that the wire extends somewhat after being heated for the first time. Stretch the wire slightly by the first heating and tension it again. The wire will now retain its length.

''Miter cutting''
''Miter cutting''<br>
Miter cutting can be done in two ways with the THERMOCUT: by adjusting the spool carrier on the overarm or with the adjustable angle gauge.

# To adjust the spool carrier, loosen the screws 1 and 2 (Fig. 3) and select the required angle by sliding the spool carrier. Tighten the screw 1 again and tension the wire as usual.

Note:
Note: Adjusting the spool carrier will lengthen the heated part of the wire and thus increase the electrical resistance. The temperature must be adjusted accordingly.

Note:
Note: The stop can be fixed for parallel cutting. Turn the screw 1 (Fig.5) to clamp the stop in the slot. Guide the workpiece past the cutting wire along the stop.

====Demonstration====
Pick an angle between 45 and 80 degrees, and set the hot wire to your desired angle by adjusting the spool carrier.
Turn on the Thermocut and perform a miter cut on a scrap piece of foam.
Reset the angle of the hot wire perpendicular to the table top.
====General Procedure====
====General Procedure====
The tabletop foam cutter is best for performing straight, miter, and parallel cuts. Odd shapes and rounded features may be better cut with the handheld foam cutter. Only the handheld foam cutter can have its hot wire bent into odd shapes. Loosen the adjustment knobs and bend the wire to your liking.
When you finish using a foam cutter, turn it off. The hot wire should cool down in a few seconds. Gently wipe down the hot wire with a soft cloth or paper towel to remove any leftover residue.
If you are gluing foam together, cut the foam before the glue dries. The foam cutters will not work well through dried glue.

Clearly, getting burned by the hot wire is a safety concern. Don’t touch the hot wire. However, a much greater risk is the potential for dangerous fumes when cutting foams - especially foams other than polystyrene. It is very important that you verify that any other foams are safe to be cut.,

* The wire has a higher temperature at the exit side of the workpiece, which may cause surface melting. To prevent this, the wire can be cooled by blowing on it.

* Small sections of long profiles can best be cut by laying a waste piece 1 (Fig. 6) between the stop and the work piece and then cutting against the stop. The cutting wire then cuts into the waste piece and the edges remain clean.

* You can make a simple device yourself for cutting circular segments. Fix a drawing-pin at the center of the required circle on the working table with a piece of tape. Fix the workpiece onto the pin and turn the workpiece around the pin (Fig. 7).

* The cutting wire normally breaks above the guide bushing. Insert the wire a few inches further in the lower wire guide and fasten it again at regular intervals to prevent the wire from breaking.

If the wire breaks, loosen the clamping knob and remove the broken piece. Then loosen the spool screw, pull out more wire and place it into the wire hole. Re-tighten all of the screws.
