[Anshan lightning protection and grounding exothermic welding mold material] exothermic welding mold long life is the ability to re-use, and solder powder is disposable, like welders and welding. Exothermic welding mold life in general in more than 100 times longer life models, such as the word welding (especially welding wires, rods and other cylindrical shape of the conductor), and some models slightly shorter life expectancy, for example, cross-shaped molds, buy put Please verify before heat welding appliances welding what shape the specific needs of the conductor, the specification is what? (copper is 40 × 4? 50 × 5? 40 × 5?, or other specifications? Copper is 70mm2? 95mm2? 120mm2? 150mm2? 185mm2?, or other specifications? ground rod diameter Φ14.2? Φ17.2? Φ20? Φ22?, or other specifications?), solder joint shape is what? (word then? T word then? Phillips then? level? three-dimensional?), these problems can be found in HOTWELD selection lists.
