exothermic powder features: 1. UL listed 2. Good production capacity 3. Various amounts packing ANCHOR exothermic welding in under the high temperature caused by the alumino-thermic reaction to realize the high quality weld connection. This alumino-thermic reaction is carried out in the high temperature resistant graphite CAD weld mold. In normal conditions, more than 100 points can be welded with same mould and the reaction will spend about 4-5 seconds only.
Advantages: 1. Safty, no need professional skill or special protection. 2. No external power or heat is required, easy to operate. 3. The purity of welded point≥97%, so it has high conductivity and anti-corrosion.
