Preparation For Welding; Overheating Protection - Leister FUSION 2 Instrucciones De Funcionamiento

Preparation for welding

• The tool rest (8) or handle (9) can alternatively be mounted left of right of the tool.
• When using an extension cable, take care to ensure the minimum cable cross-section:
• Extension cables must be approved for the place of work (e.g. outdoors) and labelled accordingly.
• If a generator is used to supply electricity, the rated power of the generator must be 2x the rated power of the
hand extruder.
The hand extruder must not be operated in inflammable environments or where explosion hazards
exist. Ensure stable positioning during operation. The connecting cable and the welding rod must
remain unimpeded and must not hinder the user or others during operation.
Welding rod
Welding rod, PE / PP Ø 3 or Ø 4 mm
– Only use for the hand extruder without
labeling (see picture A).
Welding rod, PE / PP Ø 4 or Ø 5 mm
– Only use for the hand extruder with
labeling (see picture B).
Switching on
• Connect the hand extruder to the mains supply.
• Switch on the tool at the hot air blower switch (1).
• Adjust the hot air temperature at the air temperature potentiometer (2).
• The operating temperature is reached after approximately 10 minutes
Starting protection
The tool is equipped with current overload protection. The drive switches off automatically if current consumption
is too high. The drive can for example not be started, or only for a brief time, if the material in the screw
is insufficiently plastizised.

Overheating protection

If the drive overheats as a result of external influences or if the melting temperature of the material in the screw
is too low, the internal temperature protection switches off the drive. The overheating protection switches on
again automatically once the drive has cooled down.
