Notes
For satisfactory welding quality, the following instructions must be observed.
• Before the automatic welder is used, test welds are to be carried out in accordance with the welding instruc-
tions of the material manufacturer and with national standards or guidelines. The test welds must be checked.
• The maximum overlap width of the lower and upper membranes is 125 mm.
• The sealing sheets must be clean and dry between the overlaps and on the upper and lower side.
• Welding is not permitted in case of precipitation or through puddles.
• Wait until the device has cooled down.
• Check the
power cord (1)
and plug for electrical and/or mechanical damage.
• Clean the
hot wedge (15)
and the
drive/pressure rollers (9/11)
as well as the
contacting sys-
tem (13/14)
with the brass brush.
Do not touch moving parts
There is a risk of inadvertently becoming caught and being pulled in. Do not wear loose articles of
clothing such as scarves or shawls. Tie up long hair or protect it by wearing headgear.
Risk of burns
Do not touch hot wedge and surrounding parts when hot. Only touch the device at the handles and
operating units and always let it cool down.
12.3. Welding process
• Unlock the
clamping lever lock (5)
and open the
clamping lever (4)
shortly before the end of the welding
seam. The
upper drive/pressure roller (9)
and the
lower drive/pressure roller (11)
must never run directly
on one another.
• Switch the drive and heating off using the
Drive on/off (37)
and
Heating on/off (38)
keys. The
Heating on/off
(38)
key must be held down for 2 seconds.
• Switch off the device with the
main switch (17)
and disconnect the
power cord (1)
from the electrical mains.
If the drive is switched on, then the welding parameters in the
working display (42)
are set as follows:
• The drive speed and hot wedge temperature welding parameters can be changed at any time during welding
• Once you have set all welding parameters in line with your requirements, start the heating. The
Heating on/off
(38)
key must be held down for 2 seconds.
• As soon as the heating switches on, the
status LED
of the
Heating On/Off
(38)
key lights up. An arrow point-
ing upwards appears next to the setpoint value of the hot-wedge temperature in the
display fields (42)
. The
hot-wedge temperature increases.
• Make sure that the hot-wedge temperature has been reached before commencing work. The heat-up time is
2 to 3 minutes.
• Insert the hot wedge welding machine into the overlapping plastic sheets.
• Start the drive using the
Drive on/off (37)
key.
• Close the
clamping lever (4),
so that the
clamping lever lock (5)
engages.
• During the welding process, the hot wedge welding machine can be guided along the overlap using the
handles (2)
or the optional guide bar.
