(2500oF) and a localized release of smoke. These materials are not explosive. Ignition temperatures are in excess of 900oC
(1650oF) for welding material.
H. Adhering to the ERICO CADWELD PLUS welding procedures will minimize risk of burns and fire caused by hot molten
material spillage. In case of fire, use of water or CO2will aid in control of burning containers. Large quantities of water will aid
in controlling a fire should the exothermic materials become involved. Water should be applied from a distance.
1. Make sure there is proper mold fit and assembly of equipment.
2. Avoid moisture and contaminants in mold and materials being welded. Contact between hot molten metal and
moisture or contaminants may result in spewing of hot material.
3. Base material thickness must be sufficient for the size and type of connection being made to prevent melt-through
and leakage of hot molten metal.
I. Applications or conditions may exist which require special considerations. The following are examples, but are not intended to
be a complete listing of applications/conditions.
Do not overreach. Keep proper footing and balance at all
times. Proper footing and balance enable better control in
unexpected situations.
Use safety equipment. Always wear protective
eyewear and gloves during operation.

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 may 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

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.

OPERATION
User must be familiar with and follow all applicable statutes, codes and regulations governing the workplace and personnel. Also
refer to AWS Z49.1 Safety In Welding And Cutting And Allied Processes.
NOTICE. Only ERICO CADWELD PLUS products should be used to make ERICO CADWELD PLUS connections. Follow
details in these instructions as well as the ERICO CADWELD PLUS WELDING PROCEDURE Instructions (IPX). Only properly
trained personnel should use this product. Failure to comply with ERICO procedures can result in inferior connections or
damage to conductors.
1. Dry Control Unit Termination Clip, case and hands.
If the ERICO CADWELD PLUS Control Unit case has
moisture on it, dry the case with a clean, dry towel prior
to operation.
2. Place the ERICO CADWELD PLUS Steel Cup into the
mold.
The ignition strip and termination clip should be positioned
perpendicular to the opening in the mold cover to minimize
exposure to the reaction.
3. Connect the Control Unit Termination Clip to the
ERICO CADWELD PLUS Ignition Strip. Push the Control
Unit Termination Clip onto the ERICO CADWELD PLUS
Ignition Strip until the end of the clip stop. (must push a
little past the initial resistance felt).
Figure 1
4. Keep hands and body clear of the leads and
ERICO CADWELD PLUS Ignitor Strip and mold while
making a connection. Press the OPERATE
pushbutton switch and hold down with constant
pressure. The READY light flashes for 5 to 7 seconds
as the ERICO CADWELD PLUS Control Unit charges.
Once the unit is fully charged, the READY light becomes
steady. Initiation of the reaction occurs 1 second after
the READY light is on steady. Maintain constant
pressure on the OPERATE switch until the ERICO CADWELD
PLUS reaction has been initiated. Letting go of the switch
before prior to reaction initiation will result in an internal
discharge without ignition of the welding material.
5. Internal Discharge. The ERICO CADWELD PLUS Control
Unit has an internal discharge feature. Releasing the
OPERATE pushbutton switch prior to completing the
full charge cycle discharges the unit within 5 seconds.
6. Batteries. The ERICO CADWELD PLUS Control Unit must
have sufficient battery charge for operation. As the
end of battery life approaches, the 5 to 7 second
charge time will increase. Once this charge time
increases (and the READY light flashes) to 15 seconds
or more, the batteries may need to be replaced. At 20
seconds, the Control Unit circuit automatically times
out and will not operate until the batteries are replaced.
Fully charged batteries should provide approximately
400 operations.
7. Disconnect Lead. Allow 30 seconds for the
completion of the reaction and the solidification of the
molten metal. Remove used Control Unit Ignitor Strip
from Control Unit Termination Clip.
