Nozzle Heater Temperature, Flow Rate and Temperature:
The nozzle heater temperature
(TempºC) (B) can be programmed from 0ºC to 450ºC.
The nozzle flow rate
(Rate%) (A) can be programmed from 15% to 110% (100% represents 2.75 scfm).
A flow rate range between 15% and 19% allows a maximum temperature of 325ºC.
Air / Nitrogen Option:
The pressure source connection for the upper heater can be Air or Nitrogen (D) . Selecting the Air option
automatically connects to the upper heater to the main air source (large blue hose). The main air source
is also used by the vacuum and cooling systems. Selecting the
Nitrogen option automatically connects
the upper heater to the secondary pressure connection (smaller blue hose or yellow/black hose). This
secondary pressure source is generally connected to nitrogen. If nitrogen is not available, this required
connection must be made to air.
Note: The secondary pressure connection typically provides a more stable flow rate environment and
should be considered for all placement/soldering events.
Note: If nitrogen conservation is a critical facilities issue, applications can be programmed to only use
the nitrogen option during process steps where stabile flow rate is essential.
