If the data log is enabled the display will display an Abraded/Tight? query
(green for yes, red for no) This acts as a memory jogger to confirm that
this operation has been done. Press the START button and the
temperature and temperature compensated time selected will be shown.
Press START again to begin welding.
During the weld, the display will show the combined welding and cooling
time counting down to zero, and the weld number. The unit will monitor
the welding to make sure it does not go out of limits. Any faults that are
detected will terminate the welding and cause an error message to be
displayed. These are listed later on in this manual.
The fittings must not be touched or disconnected during the cooling
period; doing so will cause a fault to be recorded on the data log and a
faulty joint may result.
At the end of the cooling period the display will ask for the output lead to
be disconnected from the fitting. Doing this will reset the unit back to the
‘connect lead and fittings’ option, ie; in readiness for the next weld to be
progressed.
MULTIPLE CONNECTIONS
The unit can weld multiple joints in series.
Do not exceed the numbers shown in the table below.
Do not mix size 1.5”-4” fittings with size 6” fittings in the same fusion
weld cycle.
Joints can be connected in series using the link cables provided.
