Remedy:
(a) See Problem F.
(b) See Problem G.
(c) See Problem H.
4. Conductor movement.
Problem J
The riser is too high.
Check for:
1. Use of proper welding material size (see mold
tag).
2. Moisture in mold or conductor.
Remedy:
(a) See Problem D.
Problem K
The mold wears out quickly.
(molds should produce an average of 50 connections.)
Remedy:
1. Use CADWELD
® B-265 cable clamp for
hard-drawn copper or DSA Copperweld ® .
2. Clean the mold with a soft brush, clean cloth,
or newspaper. DO NOT USE A WIRE BRUSH.
3. Use care in removing the mold from a finished
connection to prevent chipping of mold.
Problem l
When welding to steel, the weld does not
“stick” to the steel.
Remedy:
1. Clean the steel with a rasp or grinder to bright
metal. When grinding, use an ERICO approved
grinding wheel only. All mill scale, paint, and/or
other coating must be removed. Wire brushing
will NOT suffice. Grease must be removed with
safety solvent before cleaning.
2. Clean galvanized surfaces with a wire brush or
emery cloth. However, extra heavy galvanized
steel must be cleaned with a rasp.
3. If the steel is moist, heat with a torch (from the
back side if possible). Any carbon deposit from
the flame must be removed.
4. If conductors are not in proper position, check
the instruction sheet.
