2.49 The two sheets of the H-Pack are joined together using the pre-heated
welding tool. This tool is to be used as follows.
2.49.1 The tool should be plugged into a suitable mains outlet and left to
heat up on setting three for 5-10 minutes to allow the tool to stabilize.
2.49.2 Test welds are to be carried out on a piece of sample H-Pack to
ensure the tool is at the correct temperature and is functioning
correctly.
Test the welds by gently pulling the welded edges apart. They must
be firmly welded to each other. Repeat if in doubt. Avoid pleats if
possible.
WARNING: THE TOOL AND WELDED AREAS ARE VERY HOT, IT IS
IMPERATIVE TO TAKE CAUTION WHEN USING THE SEALING
TOOL TO AVOID INJURY.
2.49.3 Starting at the left corner of the H-Pack, place the two sheets inside
the tool and clamp the jaws of the tool together. Squeeze the tool
handles together firmly for 10 seconds, then release hand pressure,
(FIGURE A2-24).
2.49.4 Seal the two sheets together along the 150 mm section, (the length
of the tool). Slide the tool along the length of the sheet and clamp
again to seal the next section.
NOTE: Each weld should be overlapped by minimum 10 mm
lengthwise to ensure there are no unsealed gaps left
between the sheets.
2.49.5 The heat seal should be completed so that it leaves 15 mm nominal
weld width (minimum 10 mm) from the edge of the H-Pack.
NOTE: Take care when sealing the corners of the H-Pack.
2.49.6 The heat-sealing tool should be worked around the perimeter of the
H-Pack until it is completed enclosed.
2.49.7 Test the welds by gently pulling the welded edges apart. They must
be firmly welded to each other. Repeat if in doubt.
