(b) Check to be sure gap is centered under
tap hole.
NOTE: In some cases, the run (thru) conductor
must be cut and gapped. Follow instructions for
same or use CADWELD
® Heavy Duty molds.
Problem F
The welding material leaks around the
conductor.
Remedy:
1. Use packing material around the conductor after
the mold is closed.
2. Use molds with wear plates (which also act as
chill plates).
3. Check for the proper mold. Mold must be sized
for the cable being welded.
4. If the mold is excessively worn, replace with a
new mold.
Problem G
The connection has “fins”— metal is lost.
Check for:
1. Mold not completely closed.
2. Mold worn beyond useful life and needs
replacement.
Problem H
The cables pull out of the mold during welding.
Remedy:
1. Use a clamp (CADWELD
® B-265) or other means
to prevent movement of conductors when
welding.
Problem I
Insufficient fill material to cover conductors
Check for:
1. Use of proper welding material size
(see mold tag).
2. Too large a gap between conductors
(see positioning instructions).
3. Mold leakage.
