Section 2.1: Hot Air Heating System
Nozzle placement is a key component in heat sealing. A properly placed nozzle will be
centered on the weld rollers approximately 1/4 - 1/2 inches away and have a slight whistle
during the welding process.
WARNING!
The Hot Air Heating System near the Nozzle and the Nozzle Clamp is very
hot and will cause burning if not allowed to cool before handling. Turn the
Heat and Power Switches to the off position and allow the Hot Air Heating
System to cool for at least 30 minutes before touching with bare skin.
Length of time may vary depending on ambient temperature and
environmental conditions.
Adjusting Nozzle
When an adjustment is needed, set the desired Weld Roller pressure (or P.S.I.) and turn
the Speed Control to the lowest setting. Make the adjustment, and then check the Nozzle
placement by engaging the Drive Foot Switch.
The angle of the Nozzle must be adjusted after the machine has cooled down to avoid
personal injury. While all other Nozzle adjustments must be made after the machine has
been brought up to welding temperature.
The Weld Roller Pressure and the temperature of the Nozzle both play an important
role in the placement of the Nozzle. Varying Weld Roller Pressure (or P.S.I.) will change the
position of the Weld Roller Pinch Point causing the Nozzle to become misaligned. The
Nozzle placement will also change when welding at different temperatures. As the
temperature increases, the Nozzle expands lowering it’s position on the Weld Rollers. As
the Temperature decreases, the Nozzle contracts raising it’s position on the Weld Rollers.
Check the placement of the Nozzle when the temperature is changed more than 200
degrees F (93 degrees C) or the Weld Roller Pressure is changed more than
10 p.s.i.
NOTE:
Every 200° F change in temperature will require realignment of Nozzle.
