Adjustment of the gas pressure at the
operating panel
Size and energy of the burner flame can be adjusted at the
valve of the burner hand piece or set at the operating panel by
pre-selecting the gas pressure.
When the unit is ready for operation the display shows 2
different operating pressure values (see illustration 4.8)
First part of display top line: shows the actual value (mbar)
measured in the unit.
Second part of display top line: shows the actual reactor power
required to produce the set gas pressure. The display shows a
value between 0% and 100%.
Shows the actual set pressure value (mbar) in the unit.
The set pressure value can be changed during operation by the
keys
or
The actual pressure is adjusted to the set value within a very
short time.
The maximum operating pressure is limited to 200 mbar, the
minimum gas pressure is limited to 50 mbar.
The display shows the actual operating pressure in the top line,
e.g. 120 mbar. If the set pressure value is changed, e.g. to 140
mbar, the reactor will go on full power immediately (100%)
power to reach this value.
120 mbar 100%
140 mbar (set)
As soon as the gas pressure has reached the set value, the gas
output is reduced to the value, which is required for keeping the
gas pressure stable at level of the set gas pressure, e.g. at
75%. The required gas output depends on the applied nozzle
size and the set gas pressure.
140 mbar 75%
140 mbar (set)
The gas pressure should be between 50 and 150 mbar
depending on the soldering or welding job. It may be necessary
to reduce the number of burners used at the same time or to
reduce the nozzle size.
The flame becomes „harder“ with increasing gas pressure, and
„softer“ with decreasing gas pressure. The Lötstar unit allows
the perfect adjustment of the flame to each soldering or welding
job.
