• The
handle (11)
can alternatively be mounted left, right or bottom of the tool.
• Ensure the minimum cross-section when using extension cables. The extension cable must be approved for the
site of use (e.g. in the open air) and marked correspondingly. When using a power unit for power supply, it’s
nominal power rating is: 2 x nominal power rating of the hand extruder.
Starting the welding process
• Fit the required WELDY
welding shoe (1) according to the paragraph “change of the welding shoe”.
• Welding can begin once the operating temperature has been attained.
Operate the tool drive on/off switch (10) for this purpose, operate the tool only when feed welding rod of 3 or
4 mm diameter into the welding rod opening (4) and allow a small amount plasticized material to escape.
• Adjust the heat of the tool until it reaches the ideal temperature to start the work.
Starting protection
The tool is equipped with current overload protection fuse (8). In case of too high current consumption,
the drive will switch off automaticaly if the material in the screw is insufficiently plasticized. Wait for 1
minute; press the overload protection fuse (8), the tool will re-start again.
• Connect the WELDY hand extruder to the mains supply.
• Switch on the tool at the
hot air blower switch (13).
• Adjust the hot air temperature by the
air temperature potentiometer (12) to position 7.
Switching on
In order to reach the operating temperature the tool needs to heat up
for at least 10 minutes.
DANGER!
Never feed welding rod into both welding rod openings at the same time.
Keep the welding rod feed clean and dry.
