PRINCIPALS OF HEAT SEALING
Heat
Hot Air Heating System
The Heat required for the welding operation is created electrically by one heating element
located inside the Heat Element Housing. The Internal Air Compressor pumps air over the heat
element and carries the heat through the Hot Air Nozzle, applying the heat to the material to be
welded. The hot air temperature ranges from 25 to 730 Degrees Celsius (100 to 1350 Degrees
Fahrenheit).
Hot Wedge Heating System
The Hot Wedge heat system uses four cartridge heat elements to electrically heat the Wedge.
The Hot Wedge temperature ranges from 25 to 490 Degrees Celsius (100 to 915 Degrees Fahr-
enheit).
Speed
The Speed of the Weld Rollers determines the amount of time the heat is applied to the material
being welded. The slower the speed setting, the more the material will be heated. The faster the
speed setting, the less the material will be heated. To achieve the best weld, a minimal amount
of heat should be applied to the material while still achieving a full weld. Too much heat will
cause distortion of the material; while not enough heat will prevent the material from welding.
Pressure
The pressure of the weld roller is the final step when creating a weld. The pressure of the weld
roller compresses the heated material together completing the welding process.
Summary
When heat sealing, the correct combination of heat, speed, and pressure will allow you to
achieve a properly welded seam.
