Starting the welding process
• Fit the required welding shoe (8) according to the paragraph "Changing the welding shoe" (see page 27).
• Connect the hand extruder to the mains supply.
• Switch on the tool at the main switch (1).
• Set the potentiometer (3) to max.
• Once the operating temperature is reached («READY*» status), welding can begin.
• Activate the motor on/off switch (2).
• Feed welding rod into the welding rod opening (12) (see chapter welding rod) and allow a small amount
plastizised material to escape.
• The welding rod is automatically drawn in through the welding rod opening (12). The rod should feed in without
resistance.
CAUTION ! Never insert into both welding rod openings simultaneously. Never operate the tool
without welding rod.
• Interrupt the passage of plastizised material with the motor on/off switch (2).
• Direct the pre-heating nozzle (9) towards the welding zone.
• Preheat the welding zone with a fanning motion.
• Place the tool over the prepared welding zone and reactivate the motor on/off switch (2).
• Carry out a test weld according to the welding instruction of the material manufacturer and national standards or
guidelines.
• Check the test weld.
• Adjust the temperature setting and welding output as required (Seite 22).
• For a prolonged welding process, the motor on/off switch (2) can be kept in continuous operation by means of
the locking device (4).
