WELDPLAST 600/605
hot air welder extruder
Congratulations on your purchase of the WELDPLAST 600/605.
You have chosen a first-class hot air welder extruder.
It was developed and produced in accordance with the latest state-of-the-art technology in the plastics-process-
ing industry. It has also been manufactured using high-quality materials.
You can find more information on the WELDPLAST 600/605 at www.leister.com
We recommend that you always keep the instruction manual with the device.
1. Important safety instructions
In addition to the safety instructions contained in the individual sections of this instruction manual, the following
regulations must always be observed.
Read through the operating instructions before using for the first time. Always store these operating
instructions with the device.
Do not pass the device on to anyone else without the operating instructions.
Warning
Hazardous voltage, danger to life
There is a danger to life from electric shock due to electrical voltage. The extruder must therefore only
be connected to sockets and extension cables with a protective earth conductor. Protect the extruder
from moisture and wet conditions. Before starting the device, check the power cord, the plug and the
extension cable for electrical and mechanical damage. The extruder may only be opened by instructed,
qualified personnel.
Risk of burning
Do not touch exposed metal parts or escaping material while they are hot. The device should always
first be allowed to cool down. Never point the hot air flow at people or animals.
The local supply voltage must match the nominal voltage specified on the device. In case of doubt,
the responsible power company must be consulted.
The main switch must be switched o in the event of a mains voltage failure.
Risk of glare
Direct eye contact with the LED light beam must be avoided.
The device should only be operated by trained specialists or under their supervision. Children are not
permitted to operate the device.

6.1 Work environment and safety
Warning
Caution
Hazardous voltage, danger to life
There is a danger to life from electric shock due to electrical voltage. The extruder must therefore only
be connected to sockets and extension cables with a protective earth conductor. Protect the extruder
from moisture and wet conditions. Before starting the device, check the power cord, the plug and the
extension cable for electrical and mechanical damage.
Risk of burning
Do not touch exposed metal parts or escaping material while they are hot. The device should always
first be allowed to cool down. Never point the hot air flow at people or animals.
Risk of fire and explosion
Caused by improper use of the extruder (e.g., material overheating), and particularly in the vicinity of
flammable materials and explosive gases.
Never use the hot air welder extruder in explosive or readily inflammable surroundings. Maintain su-
cient distance from combustible materials or explosive gases at all times.
Place the handheld extruder exclusively on fireproof surfaces. Hot metal parts and the warm air jet
must be kept at a sucient distance from the support and walls.
The device must be monitored continuously during operation. Waste heat can come into contact with
flammable materials that are not in view.
Ensure that you are in a stable position while working. The connection cables and welding rod must be
able to move freely and must not hinder the user or third parties while working. (Tripping hazard).
Comply with national statutory requirements regarding occupational safety (securing personnel or
devices).
If the device is being used on construction sites, a fault current circuit breaker must be used to
protect site personnel.
The device should only be operated by trained specialists or under their supervision. Children are not
permitted to operate the device.

Power cord and extension cable
Power supply with autonomous power generators
• The nominal voltage specified on the device (see Technical data [2]) must match the supply voltage.
• The extension cables must be authorized for the utilization site (such as, outdoors) and be marked accordingly.
Take the necessary minimum cross-section for extension cables into account. Recommendation at least 2.5
mm2.
• When using autonomous power generators, they must be grounded and equipped with residual current circuit
breakers.
To prevent possible damage to the electronics, Leister recommends power generators that have a maximum
total harmonic distortion (THD) of 5% or less.
• The formula "2 x nominal power of the hot air extruder" applies to the design of the nominal power of power
generators.
• The device may only be switched on and o when the generator is running, otherwise the electronic compo-
nents may be damaged.
• Disconnect the device from the mains before starting or switching o the generator.
• Place the hot air welder extruder on a suitable surface so that the device is stable and safe. Make sure that
nothing flammable is radiated by the heat of the extruder.
• Check whether the material to be welded is clean.
• Then check whether the welding shoe (9) is clean.
• Check the preheating nozzle (12) is in the right position and tightened.
• Check the power cord (1) and plug for electrical and/or mechanical damage.
6.2 Prepare device
6.3 Starting the device
• Once you have prepared the working area and the hot air welder in accordance with
the description, connect the hot air welder to the supply voltage.
• Use the main switch (18) to switch the hot-air welder extruder on.
After startup, the Start screen will appear briefly in the display with the
version number of the current software release and the device designation.
If the device was allowed to cool down beforehand, this will be followed by a static
display of the setpoints of the most recently used profile (the Basic profile is displayed
when the device is first commissioned).
The heating is not yet switched on at this stage.
• Now select the appropriate welding formula (see 9.3) or set the welding parameters
individually.
• Now control the heating with the Heating On/O button (31).

14
6.4 Welding sequence
Preparing for welding
• Now carry out test welds in accordance with the welding instructions of the material manufacturer and/or
national standards or regulations and inspect the results. Adjust the welding profile as required.
• By pressing the drive on/o switch (16), the plastic drive starts extruding the inserted welding rod.
• Extrude some material without welding before the actual welding process.
• Guide the extruder during the welding process keeping it stable. The preheating nozzle must heat the
surfaces to be welded.
• Never feed the welding rod into both welding rod insertion points (11) at the same time. Always operate the
extruder with the welding rod.
As soon as you have switched on the heating (Button 31 Heating On/O), you will
see adynamic display of the current air and plastic temperature with a prog-
ress bar (setpoint and actual values).
The plastic drive is still locked.
If the ACTUAL temperature of the plastic is 30°C below the DESIRED temperature,
the 5-minute timer starts. When the timer has expired, the plastic drive is enabled.
The plastic and air temperatures have now been reached. The plastic drive is
enabled.

15
6.5 Finishing welding
6.6 Switching off the device/Maintenance
• To stop the plastic output, press the drive on/o switch (16). Slowly swivel the welding shoe away from the
welding seam.
• Pull out any material left over in the welding shoe hole.
• Cut o the welding rod.
• Pull out any remaining material in the welding shoe hole.
Switch o the air/plastic heaters with the button (31). The cool-down mode is
activated.
• Note that the jacket heater (10) remains hot for a certain time after the cool-
down mode has been completed.
• The blower switches o automatically after approx. 6minutes.
• Now switch o the device with the main switch (18) and disconnect the power
cord (1) from the electrical network.
• Wait until the device has cooled down fully.
• Check the power cord (1) and plug for electrical and/or mechanical damage.
