Part A: Guidelines
17. For the correct handling of welding machines the following must
be observed:
General Regulations for Protection of Labour and Prevention of Ac-
cidents and particularly the Regulations of the Employers’ Liability
Insurance Asso-ciation of the Chemical Industry regarding Ma-
chines for the Processing of Plastics, chapter: „Welding Machines
and Welding Equipment“.
18. For the handling of aquatherm- welding machines, devices and
tools please observe General Regulations DVS 2208 Part 1 of the
German Association for Welding Engineering, Registered Society
(Deutscher Verband für Schweißtechnik e. V.).
Part B: Checking of devices and tools
1. Check, if the aquatherm- welding devices and tools comply with to
the guidelines “Fusion Part A”.
2. All used devices and tools must have reached the necessary
operating temperature of 260 °C. This requires acc. to “Fusion Part
A, item 8” a separate test, which is indispensable (DVS - Welding
Guidelines):
Suitable measuring instruments have to measure a temperature of up
to 350° C with a high accuracy.
NOTE
:
aquatherm recommends the original aquatherm temperature measu-
ring device art.-no. 50188
PART B: PREPARATION FOR THE FUSION
3. Cut the pipe at right angles to the pipe axis. Only use aquatherm
pipe cutters or other suitable cutting pliers. Take care that the
pipe axis is free from burrs or cutting debris and remove where
necessary.
4. Mark the welding depth at the end of the pipe with the enclosed
pencil and template.
5. Mark the desired position of the fitting on the pipe and / or fitting.
The markings on the fitting and the uninterrupted line on the pipe
may be used as a guide.
