5. GENERAL WELDING CRITERIA
The quality of the joint depends on your scrupulous compliance
with the following recommendations.
HANDLING THE PIPES AND COUPLERS
During welding, the pipes and couplers must be at
near-ambient temperature, as detected by the
welder’s temperature probe. They must
consequently be protected from direct sunlight
both before and during welding, since they could
otherwise become much warmer than the
ambient temperature, with a consequent
negative effect on the electro-melting process
(i.e. excessive melting of the pipe and coupler).
In the case of excessively high temperatures,
move the pipes and coupler to a cool, shady
place and wait for their temperature to return to
near-ambient values.
Cut the ends of the pipes
being prepared for welding
at right-angles, using
suitable pipe-cutting tools.
Pay attention to avoid both
bending and ovalizing of
the pipe.
Make sure to obtain an
even, overall scraping
action extending over at
least 1 cm for each half of
the coupler.
Scraping with sandpaper,
rasps, or emery grinding
wheels is absolutely
unsuitable.
Smoothly scrape off the
oxidized surface layer from
the pipe using suitable tools.
Remove the coupler from its packaging only just before it is
used and clean the inside of the coupler in compliance with
the manufacturer’s instructions.
Slide the ends of the pipes into the coupler. It is advisable to
align the pipe and couplers in order:
• to ensure that the parts remain in a stable position
throughout the welding and cooling phases;
• to avoid any mechanical strain on the joint during the
welding and cooling phases.
An aligning device can be used to achieve optimal aligning.
The welding must be performed as soon as possible after the
cleaning Pipes and fittings must be made of the same polymer
or compatible substances. Compatibility between polymer has
to be stated by the manufacturer.
Never weld a coupler twice.
Check that no water has accumulated in the product and, if
necessary, turn the machine so that the water comes out of
the ventilation grille.
The cooling time varies, depending on the diameter of the
couplers and the ambient temperature. Always comply with
the cooling-time recommendations given by the couplers’
manufacturer.
The removal of the aligning devices and disconnection of the
welding cables must be done only after the cooling phase has
come to a complete end.
6. OPERATING INSTRUCTIONS
PREPARATION
Prepare the pipes and the coupler for welding in compliance
with the recommendations given in the “General Welding
Criteria” section of this manual and furthermore the
recommendations of the coupler’s manufacturer.
SETUP
Connect the equipment to the mains and turn on the main
switch.
when the Elektra is
switched on for the very first time,
the picture on the right-side will
show up, as some settings will be
requested (Language, Time and
Date format STARTUP Seite 109).
Connect the leads to the coupler.
The terminal leads above must ensure a
good electric conductivity to avoid overheating and
eventually irreversible damages. Make sure that the terminal
leads are not dirty nor clogged. Clean them if necessary.
