How do you ignite Cadweld?
YOU MUST SQUEEZE THE BOTTOM OF THE CONTAINER AND/OR HIT IT ON THE EDGE OF THE MOLD TO GET THE FINE POWER ( COMPACTED UNDER PRESSURE IN BOTTOM OF BLUE TUBE) TO FALL OUT….. This fine powder is the material that will ignite the other powder.
What is Cadweld powder made of?
Specifying the Cadweld Process in your construction plans will dramatically extend the lifespan of infrastructure systems. Cadweld connections are made with a semi-permanent graphite mold, which holds the conductors to be welded. Weld metal (a mixture of copper oxide and aluminum) is dumped into the top of the mold.
How does a Cadweld work?
nVent ERICO Cadweld is the brand name of an exothermic weld, which means that it uses molten metal to permanently join conductors. Typically, thermite powder (powdered aluminum and iron oxide) is poured into a graphite mold, then ignited. The thermite becomes molten, reaching temperatures in excess of 2500°F.
How long does a Cadweld mold last?
Q: How long does a Cadweld mold last? The factory spec’s their semi-permanent molds to last approx. 50 connections. This number can be greatly affected by the amount of care taken while using and cleaning the mold.
Is it legal to make thermite?
Thermite has many legitimate uses in industry, such as welding railroad tracks and construction/demolition work. Many sites sell thermite ingredients and kits and many videos of thermite reactions are featured on YouTube, so it generally isn’t illegal to make thermite in the United States.
Can you ignite thermite with a sparkler?
Apart from magnesium ignition, some amateurs also choose to use sparklers to ignite the thermite mixture. This can be a dangerous method, as the iron sparks, like the magnesium strips, burn at thousands of degrees and can ignite the thermite, though the sparkler itself is not in contact with it.

What do you need to make a Cadweld welding unit?
1. CADWELD engineered mold. 2. Welding material required by your mold. 3. Handle clamps and or frame. 4. CADWELD PLUScontrol unit or flint ignitor. 5. Lugs, sleeves, packing material listed on the page with the mold as required.
What should I do before making a CADWELD connection?
The conductors should be clean and dry before the connection is made. Use a propane torch to dry wire conductors and remove remaining cleaning residue, solvent, or water before making the CADWELD® connection. Next, use a wire brush to further prepare the surface of the conductors (CADWELD T-313 or T-314 brush).
