Important Safety Instructions

Warning
Risk of death from electric shock due to dangerous electrical voltage

The device is only to be connected to sockets and extension cables with a protective earth conductor.
Protect the device from moisture and wet conditions.
When used on a construction site, a residual current circuit breaker is mandatory.
Before using the device for the first time, check the power cord, the plug, and the extension cable for electrical and mechanical damage.
Pull the mains plug from the outlet before opening the device.

Danger of fire and explosion with improper installation and use

Avoid overheating of the material.
Never place the device near combustible materials and/or explosive gases.
Never place the device close to combustible materials and/or explosive gases while it is running and/or hot.
Secure the device in a resting position against falling/rolling.

Risk of burns due to hot equipment parts and hot air jet

Do not touch the heating tube and nozzle when they are hot. The device should always be allowed to cool down first.
Never point the hot air flow at people and/or animals.

Caution

Ensure that the local supply voltage matches the nominal voltage specified on the device.
Only operate the device under supervision. Waste heat can come into contact with nearby flammable materials.
The device should only be operated by trained specialists or under their supervision. Children are not permitted to operate the device.

Application

Intended use
The PENWELD external air-operated hot-air welder is always equipped with an air source (e.g. AIRSTREAM ST or AIRSTREAM 100 from Leister – for requirements/limit values, see Chapter 3).

Applications:

Welding, shrinking, and deforming of plastics
Drying of aqueous-moist surfaces
Shrinking of heat shrink hoses, films, tapes, soldering connectors and molded parts
Soldering of copper pipes, soldering connectors, and metal foils
Activating and dissolving solvent-free adhesives
Removing plastic press burrs

Non-intended use
Any other use or any use beyond the type of use described is deemed non- intended use.

Technical Data

Subject to change without prior notice.

Values were determined at an air volume flow of 80 l/min (outlet of heating tube device).
Values determined together with AIRSTREAM 100
The air volume at the nozzle is smaller because around 20 % of the supply air volume is required for protective tube cooling.

Dimensions

Terminal box
Only attach the connection box to the points provided for this purpose.

Using PENWELD For the First Time

Risk of death from electric shock due to dangerous electrical voltage

The device is only to be connected to sockets and extension cables with a protective earth conductor.
Protect the device from moisture and wet conditions.
When used on a construction site, a residual current circuit breaker is mandatory.
Before using the device for the first time, check the power cord, the plug, and the extension cable for electrical and mechanical damage.

Danger of fire and explosion with improper installation and use

Avoid overheating of the material.
Never place the device near combustible materials and/or explosive gases.
Never place the device close to combustible materials and/or explosive gases while it is running and/or hot.
Secure the device in a resting position against falling/rolling.

Fire and explosion hazard in the event of a grid interruption

Note that depending on the configuration/setting, the heater starts automatically after a mains interruption and the device regulates itself to the last set temperature.
Place the device in a correct resting position during power mains interruption: not near flammable materials and/or explosive gases; never pointed at objects, people or animals).

Tripping hazard when air hose is not carefully placed

Note that there is a risk of tripping if the air hose is not carefully placed.
Ensure that hoses/lines are free to move and do not interfere with users or third parties at work.

The danger of glare due to the work light of the PENWELD A

Avoid direct eye contact with the work light.

Risk of poisoning when working with plastics, paints, and similar materials

Note that when working with plastics, paints, and similar materials, aggressive and/or toxic gases may be produced.
Avoid breathing in vapors, even if they seem to be harmless.
Consider the material specifications and use the correct welding parameters.
Always ensure good ventilation of the workplace when working.
Wear a respirator.

Air supply

To protect the unit and heating element, do not fail to meet the minimum air volume and do not exceed the maximum supply air temperature (see technical data). If the minimum air volume is no longer present, then the heating output must be interrupted at once.
Note the flow direction.
The maximum air pressure must never be exceeded in the compressed air connection (see technical data).
Use an air filter if there is dusty air. In cases of particularly critical dust (e.g. metal, electrically conductive, or moist dust), special filters must be used to avoid short circuits in the device.

Caution

Always operate the device with an air supply.
At the end of each unit use, turn off the heating.
After turning off the heater, hold the air supply for a few minutes to cool the unit.

**Install nozzle***

Danger of burns when touching the hot nozzle
- Before installing or changing the nozzle, allow the unit to cool completely or use suitable tools.
Fire hazard due to hot nozzle
- Note that the hot nozzle can ignite flammable materials.
- Place the hot nozzle on a fireproof surface.
Risk of equipment damage due to hot air jam
- Note that an incorrect or defective nozzle can cause hot air to jam, which damages the device.
- Only use suitable original Leister nozzles for the device.

Operating Instruction

Operating the PENWELD S
The control unit of the PENWELD S consists of the rotary knob (5.2). Using the scale (1–10), use the rotary knob (5.2) to continuously adjust the target temperature. The following graphic shows the temperature curve by adjusting the rotary knob.

These are guide values determined using an air source of 80l/min. None of the data is guaranteed.

Turning on the PENWELD S

Caution
