Switching Off - WELDY booster EX2 Instrucciones De Funcionamiento

Starting the welding process
• Direct the welding shoe (1) to the welding zone.
• Preheat the welding area by moving the hand extruder back and forth.
• Place the handheld extruder in the prepared welding area and press the on/off switch (10).
• Perform a welding test and check the result.
• Correct the hot air temperature on the air temperature controller (12), if necessary.
• In case of a prolonged welding process, locking device drive on/off switch (9) can be held in the active state
with the locking tool.
• Make sure there is enough clean welding rod on your unwinding unit.
• The welding rod is automatically drawn through the welding rod opening (4) after starting. The infeed of the
welding rod must not be hindered. Keep the welding rod clean and dry.

Switching off

• Release the locking device on/off switch (9) by briefly pressing the on/off switch (10). Remove the
welding material from the welding shoe (1) in order to prevent damage to the welding shoe the next time
it is started.
• The handheld extruder may only be placed on the tool support (3).
Risk of burning:
Do not touch exposed metal parts or molten material
while hot. Allow the device to cool down first after
operation or before mechanical settings. Never point
the hot air flow at people or animals.
• Set the air temperature controller (12) to "0" and wait until the handheld extruder has cooled down.
• Switch off the hot air blower switch (13).
Checking the temperature of the extrudate and the prewarming air
The temperature of the extrudate and the hot air flow must be checked regularly during extended periods of
welding work: Fast-indicating electronic temperature probes with suitable temperature sensors must be used for
this purpose. The highest temperature in the hot air jet between the nozzle outlet and at a depth of 5 mm must be
determined. For temperature measurement, the temperature sensor must be inserted in the welding shoe in the
middle of the extrudate.
Welding direction
• The welding shoe (1) can be turned infinitely
to the desired welding direction by loosening the
clamp screws (18).
• The clamp screws (18) must be well tightened
again.
The welding shoe may only be changed if the handheld extruder has reached its
operating temperature. Work only with heat-resistant gloves.
