WARNING  

1. ERICO products shall be installed and used only as indicated in ERICO product instruction sheets and  

  training materials. Instruction sheets are available at www.erico.com and from your ERICO customer  

  service representative. 
2. ERICO products must never be used for a purpose other than the purpose for which they were designed  

  or in a manner that exceeds specified load ratings. 
3. All instructions must be completely followed to ensure proper and safe installation and performance. 
4. Improper installation, misuse, misapplication or other failure to completely follow ERICO’s instructions  

  and warnings may cause product malfunction, property damage, serious bodily injury and death.

GENERAL AND SAFETY INSTRUCTIONS:

 

A. Only ERICO manufactured equipment and materials should be used to make CADWELD

®

 connections. 

B. Do not connect items except as detailed in instruction sheets. Failure to comply with these instructions  

  may result in improper and unsafe connections, damage to items being connected, bodily injury and  

  property damage. 
C. Do not use worn or broken equipment which could cause leakage. 
D. Do not alter equipment or material without ERICO authorization. 
E. When using CADWELD

®

 do not use welding material package if damaged or not fully intact.  

  When using CADWELD

®

 PLUS, do not tamper with or disassemble the welding material unit. 

F.  Make connections in conformance with CADWELD instructions and all governing codes. 
  1. Personnel should be properly trained in the use of this product and must wear safety glasses  

    and gloves. 
  2. Avoid contact with hot materials. 
  3. Advise nearby personnel of welding operations in the area. 
  4. Remove or protect fire hazards in the immediate area. 
  5. Provide adequate ventilation to the work area. 
  6. Do not smoke when handling starting material. 
  7. Avoid direct eye contact with “flash” of light from ignition of starting material. 
G. Welding material is an exothermic mixture and reacts to produce hot molten material with temperatures  

  in excess of 1400°C (2500°F) and a localized release of smoke. These materials are not explosive.  

  Ignition temperatures are in excess of 900°C (1650°F) for welding material. 
H. Adhering to the CADWELD welding procedures will minimize risk of burns and fire caused by hot molten  

  material spillage. In case of fire, use of water or CO

2

 will 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.

  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 CADWELD  

  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 CADWELD  

  connections, pressure (temperature) build-up and fire/chemical decomposition hazards.

  CONNECTIONS TO REBAR

 

  Application of the CADWELD 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 CADWELD 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.

WARRANTY

 

ERICO products are warranted to be free from defects in material and workmanship at the time of  

shipment. NO OTHER WARRANTY, WHETHER EXPRESS OR IMPLIED (INCLUDING ANY WARRANTY OF 

MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE), SHALL EXIST IN CONNECTION WITH THE  

SALE OR USE OF ANY ERICO PRODUCTS. Claims for errors, shortages, defects or nonconformities

All other claims must be made in writing to ERICO within 6 months from the date of shipment or  

transport. Products claimed to be nonconforming or defective must, upon ERICO’s prior written  

approval in accordance with its standard terms and procedures governing returns, promptly be returned  

to ERICO for inspection. Claims not made as provided above and within the applicable time period will  

be barred. ERICO shall in no event be responsible if the products have not been stored or used in  

accordance with its specifications and recommended procedures. ERICO will, at its option, either repair  

or replace nonconforming or defective products for which it is responsible or return the purchase price  

to the Buyer. THE FOREGOING STATES BUYER’S EXCLUSIVE REMEDY FOR ANY BREACH OF ERICO  

WARRANTY AND FOR ANY CLAIM, WHETHER SOUNDING IN CONTRACT, TORT OR NEGLIGENCE,  

FOR LOSS OR INJURY CAUSED BY THE SALE OR USE OF ANY PRODUCT.

of ERICO’s employees. Should ERICO be held liable its liability shall in no event exceed the total purchase  

price under the contract. ERICO SHALL IN NO EVENT BE RESPONSIBLE FOR ANY LOSS OF BUSINESS OR  

PROFITS, DOWNTIME OR DELAY, LABOR, REPAIR OR MATERIAL COSTS OR ANY SIMILAR OR DISSIMILAR 

CONSEQUENTIAL LOSS OR DAMAGE INCURRED BY BUYER.
