Peeling Tool -
Scrape (using hand scraper) or peel (using a
rotary peeling tool) the pipe ends to the marked
insertion depth.
It is vitally important that the pipe
surface oxidised layer is removed otherwise good
welding will not be achieved
. Also enough pipe
material must be removed to allow the pipe to fit
into the electrofusion coupler without having to
use excessive force.
Step 3 – Electrofusion Couplers
Remove the electrofusion fitting from its PE bag.
Do not touch or contaminate the internal welding
surfaces. The fusion and cooling times are printed
on the electrofusion coupler label. Terminal pins
are normally 4mm in diameter, and this is stated
on the label. Older fittings may have 4.7mm pins,
if so the label will not state the size.
