CONNECTIONS TO PIPE/VESSELS
For use with cast iron pipe or heavy casting meeting ASTM A47-84, A48-83, A126-84, A278-85, or A377-89. DO NOT USE ON
CAST IRON SOIL PIPE (ASTM A74-93). Evaluate possible effects of ERICO CADWELD PLUS connections to structural
members and thin-wall materials; vessels/piping systems that are pressurized, closed or containing (or having contained)
flammable / explosive / hazardous materials. Evaluation should be made prior to use, based on conditions of use and applicable
codes, and should incorporate as a minimum, effects of melt-through of hot material; structural/metallurgical effects of ERICO
CADWELD PLUS connections, pressure (temperature) build-up and fire/chemical decomposition hazards.
CONNECTIONS TO REBAR
Application of the ERICO CADWELD PLUS connection m
ay have an effect on the rebar’s structural integrity. The rebar’s
chemistry and the location of the weld should be considered before making any welds to the rebar. For lapped rebar splices, it is
recommended that the connections be made near the bar end at an area of minimum stress. If ERICO CADWELD PLUS Rebar
Splices are used, the grounding connection can be made to the splice sleeve with minimal effect on the structural characteristics
of the splice.
SAFETY INSTRUCTIONS: All governing codes and regulations and those required by the job site must be observed. Always
use appropriate safety equipment such as eye protection, hard hat, and gloves as appropriate to the application.
SPECIFIC SAFETY RULES
DANGER! High voltage electrical shock hazard. Keep hands and body clear of the conductors while operating.
Failure to do so can result in death or serious injury.
WARNING! Operation and maintenance of the ERICO CADWELD PLUS Control Unit should only be performed by
qualified personnel.
CAUTION! Read, understand and follow all safety instructions prior to performing any ERICO CADWELD PLUS
connection. Refer to the
ERICO
CADWELD PLUS WELDING PROCEDURE, Instructions (IPX) prior to making any
ERICO CADWELD PLUS connection.
Electrical Safety
. Do not abuse the lead. Never use the
lead to carry the Control Unit. Keep the lead away from
sharp edges or moving parts. Replace damaged leads
immediately. Damaged leads may create a safety hazard.
Control Unit Use and Care.
If damaged, have the Control
Unit serviced before using. The Control Unit service must
be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel may
result in a risk of injury. Follow the instructions in the
Maintenance section of this manual. Use of unauthorized
FUNCTIONAL DESCRIPTION
The ERICO CADWELD PLUS welding system replaces the
conventional method of using starting material and a flint
gun to ignite welding material to initiate the ERICO CADWELD
PLUS process. This is accomplished by using pre-sealed,
drop-in welding material crucible cup packages which are placed
into existing molds and using the ERICO CADWELD PLUS
Control Unit to discharge current into a pre-installed crucible
cup ignitor strip.
The ERICO CADWELD PBPLUSCU Control Unit uses
8 AA lithium batteries, a charging circuit, an output capacitor
parts or failure to follow Maintenance Instructions may
create a risk of shock or injury.
Storage.
The Control Unit lead should be wrapped around
the case prior to storage. When storing Control Unit, store
the Control Unit in such a manner as to prevent accidental
push button OPERATE switch activation.
Avoid accidental activation.
Be sure OPERATE switch
is not being pressed during insertion of ignition strip into
Control Unit termination clip.
and an electronic switch to initiate the discharge. The
charging commences once the OPERATE membrane
push button is pressed and held. The READY light
flashes to indicate charging is in process. If the
pushbutton is released, the charging ceases and the
capacitor discharges internally. In the event the lead
is not connected to the ERICO CADWELD PLUS
crucible cup ignitor strip, the capacitor discharges
internally. Once the output capacitor is fully charged
the READY light changes to steady state and then goes
out when the capacitor discharges into the crucible cup
ignitor strip to initiate the ERICO CADWELD PLUS
process.
