Please note!
If the set gas pressure value is too low for the
selected nozzle size, so that the gas burning speed is higher
than the gas escaping speed, the flame backfires into the
nozzle. In most cases, this will destroy the nozzle. The backfire
of the flame is stopped by the backfire protection device inside
the handle. In the process the backfire protection device is
contaminated and the gas flow-through capacity of the handle
piece is reduced. If this process is repeated several times the
handle piece can be choked.

Regulation of the burner flame at the burner
hand piece
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.
Do not control the burner flame down until the flame touches
the nozzle tip, as this may damage the nozzle.
6.8
Operating stops
If operation of the Lötstar is stopped for a short period of time
the burner hand piece can be hooked into the holder (delivered
with the unit) with burning flame. Ensure that the burner flame
cannot ignite any flammable substances even if the position of
the burner tip changes. It may be safer to extinguish the flame
and to shut the burner valve at the hand piece.
Always extinguish the flame and shut the burner hand piece
valve for prolonged operating stops. Switch off the gas
production at the key
I/O
at the operating panel.
The unit now automatically switches into stand-by mode. In this
operating mode, the ventilation device cools down the principal
components reactor, rectifier and main transformer at reduced
speed, so that there is no risk of overheating. When the unit has
sufficiently cooled down, the control system automatically
switches off the ventilation device.
In stand-by operating mode with cooled-down unit the current
consumption is reduced to a minimum.
6.9
After operation
The unit must be switched off at the mains switch only for
prolonged operating stops (overnight, over the weekend, over
holiday periods).
Depending on how long the unit had been operated, the reactor
inside the unit can be very hot. Therefore, switch off the unit
