UPP® PIPE ELECTROFUSION WELDING: B R I D G I N G
A maximum of three primary couplers or primary electrofusion fittings may be welded
at the same time by using bridging leads. Most electrofusion couplers and fittings have
a resistance index number marked onto them inside a circle: i.e. 6. The total value of
the index number of the three items to be welded must not exceed 10. If the fitting
lacks a resistance index number then it must be treated as having an index number of
3. The 303 entry fittings have a resistance number of 3, so 3 can be welded at one time.
A list of resistance numbers can be seen in the following table.
