WELDY booster EX2 Notice D'utilisation page 6

Starting the welding process
• Carry out test welding and analyse.
• For interrupting material extrusion use the tool drive on/o switch (10).
• Direct the welding shoe (1) to the welding zone.
• Pre-warm the welding zone with back and forth movements.
• Position the tool on the prepared welding zone and operate the tool drive on/o switch (10).
• Carry out test welding and analysis.
• Adjust the hot air temperature using the air temperature potentiometer (12).
• In case of a prolonged welding process, locking device drive on/o 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 pulled in through the welding rod opening (4) automatically after starting. The welding rod
pull-in must not be impeded.
Switching o
• Release the locking device drive on/o switch (9) by briefly pressing the tool drive on/o switch (10)
and then letting go. Remove welding material from the welding shoe in order to avoid damage on the
welding shoe when starting the next time.
• The tool must only be laid down on the tool rest (3).
Front metal of tool and welding material is of
high temperature while tool is working, do not
touch them to avoid burning.
The hot air jet must not be directed towards
persons and objects.
• Adjust the air temperature potentiometer (12) to «0», let the tool to be cool down.
• Switch off the hot air blower switch (13).
Checking the temperature of the extruded material and the pre-heating temperature
The temperatures of the extruded material and the hot air jet are to be checked at regular intervals when carrying
out welding work over an extended period: Fast display electronic temperature measuring tools with the appro-
priate temperature probes have to be used. The highest temperature in the hot air jet between the nozzle outlet
plane and a depth of 5 mm is to be determined. The measurement probe must be inserted in the welding shoe in
the middle of the extruded material to measure its temperature.
Welding direction
• The welding shoe (5) 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 must only be changed when the tool has attained its operating
temperature. Work with temperature resistant gloves only.
