Welding of Polycord round belts
Process:
Engineering manual 1260
Cut Polycord round belt to length at right angles with cutting device S-16 (-> available accessories).
For determination of belt length -> manual 1260
Lock locking spring (3) in appropriate position -> label (8).
Open guiding tongs (5) and secure them by closing the bracket (4)
Open guide heads (11) by turning the knurled nuts (12).
Introduce belt ends laterally into guide heads (11) and let ends protrude 2-4 mm /
0.08-0.16 in.
,
depending on diameter (larger diameters to protrude more).
Fix belt ends by turning knurled nuts (12).
INDICATION
Fix belt without twisting, i.e. according to its „inner disposition“!
Introduce welding tool (2) with heating plate (1) between guide heads (11).
Free securing bracket (4) and carefully close guiding tongs (5).
Let belt ends melt until the bead measures about 1-2 mm /
0.04-0.08 in.
, depending on belt diameter.
Then block the handles of the guiding tongs (5) by hand, so that the guiding tongs (5) can not close
any further. This makes the belt ends stay in contact with the welding plate but without pressure
(about 5-10 s, depending on the diameter of the belt). This permits the belt ends to melt to the core
without further enlarging the bead.
WARNING
Do not inhale vapors generated during welding. Join Polycord round belts only with
good ventilation!
Slightly open the guiding tongs (5) by pressing the handles.
Pull out the welding tool (2) and place it on a flat table. At the same time, carefully close guiding
tongs (5) (joining the two melted sections).
WARNING
Do not touch the hot zone of the welding tool!.
Keep device away from water and meltable substances.
Let joint cool in guiding tongs (5) for about 1-2 min.
Open guide heads (11) by loosening the knurled nuts (12) and remove joined belt.
Open guiding tongs (5) and lock securing bracket (4).
Whenever the welding tool is not in use, pull out mains plug.
Remove bead with pliers, file or grinding disk.
Æ
see illustrations 2 and 3
The Polycord round belt is now ready for use.
WARNING
After use, disconnect the welding device from the power supply and allow it to cool
completely before storing it.
