Leister Welding-Pen A User manual

The LEISTER Welding-Pen A and S are hot air tools that can be installed for continuous
operation. They have an ergonomic shape and are light weight what makes them
suita
ble as hand tools as well as for the installation into machines and vent constructions.
The cooled heater tube as well as the LEISTER screw-on drawing nozzle with
taking tip make the Welding Pen to a very efficient tool for plastic welding.
• Welding of thermoplastic materials and also single-ply flexible plastics in the
form of boards, tubes, profiles, foams, tiles and sheets.
•
The following procedures are possible:
Rod and melt welding by means of LEISTER nozzles
• The hot air tools Welding Pen A and S need an external air-supply
(LEISTER blower or compressed air).

TEST SIGNS
TECHNICAL DATA
Danger to life when opening the tool, as live components
and connections ar exposed. Unplug the tool before
opening it.
Incorrect use of hot air blowers can cause fire and
explosion hazard, especially near combustible materials
and explosive gases.
The tool must be operated with supervision. Warmth can
reach combustible materials, which are out of sight.
For personal protection on building sites we strongly
recommend the tool be connected to a GFCI (Ground
Fault Circuit Interrupter) or a RCCB (Residual Current
Cir
cuit Breaker) .
The voltage rating stated on the tool must correspond to
the line/mains voltage.
Do not touch the element housing and nozzle when they
are hot as they can cause burns. Let the tool cool down.
Do not point hot air flow in the direction of people or
animals.
Protect tool from damp and wet.

USAGE Welding-Pen
Welding-Pen S
Welding-Pen A

Blower
• Use an air filter, if air is dusty.
• Air flow can be adjusted by the LEISTER air flow adjuster.
Compressed air
• When using compressed air, an oil and water filter must be connected.
• Air flow can be adjusted by air flow adjuster.
Operating conditions LEISTER Welding-Pen A
Fit appropriate nozzle as required.
Connect air supply with corresponding hose connection (7).
Adjust air flow by means of air flow adjuster or pressure reducing valve.
ATTENTION: Keep minimum required air flow according to data on page 2
Connect tool to the mains.
Set hot-air temperature by adjusting of air flow.
(Temperature must not exceed 600°C)
Heat up tool for about 5 minutes.
Let the tool cool down after use!
Operating conditions LEISTER Welding-Pen S
Fit appropriate nozzle as required.
Connect air supply with corresponding hose connection (7).
Adjust air flow by means of air flow adjuster or pressure reducing valve.
ATTENTION: Keep minimum required air flow according to data on page 2
Connect tool to the mains.
Adjust hot-air temperature by use of the potentiometer.
Heat up too for about 5 minutes.
Let the tool cool down after use!
Change of nozzle
• Let the tool cool down before changing the nozzle.
• Do not touch hot nozzle and only lay it on heat resistant surface because of fire
hazard.
• Nozzles can easily be screwed (M14) onto the heat protection tube.
• Use only LEISTER nozzles.

USAGE Welding-Pen
Function of heat protection Welding-Pen A
• Heating element switches off automatically if there is no or not sufficient air flow
(temperature >600°C)
Function of heat protection Welding-Pen S
• Heating element switches off automatically if there is no air flow.
• If there is not sufficient air flow, power will be electronically reduced and the
temperature keeps steady at about 600°C. If the air flow falls below a certain
value, the heating switches off automatically.
• Disconnect tool from the mains. There is an automatic reset of the circuit board
after 5 seconds.
• Check air flow
• Check hose connections
• Increase air flow
• Connect tool to the mains
• Only use LEISTER accessories
• LEISTER air flow adjuster
• PVC air hose
• Hose clamp for air hose
• Tubular nozzle ø 5 mm
• Draw nozzles with tacking tip for: rod ø 3 mm
rod ø 4 mm
profiled rod 90 – 5.7 mm
