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:
OPERATING
Leister FUSION 3
Length
Minimum cross-section (at ~230V)
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.
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 auto-
matically if current consumption is too high. The drive can for example not be star-
ted, 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.
