High Performance Thermiting Exothermic Welding Metal Powder

Product Name: High Performance Thermiting Exothermic Welding metal Powder Model NO.: 90# 115# 150# 200# 250# Grounding Materials,Pure Copper,Bron: Eathing Products, Earthing Accessories Usage: Protection Earthin Working Voltage: High Voltage Application: High Voltage Transmission Line Earthing Method: Direct Earthing Method Material: Cu, Al, Fe Certification: ISO9001, SGS Product Description PRODUCT PARAMETERSMaterialCu,Al,FeSizeCustom madeLife50~100timesCharactersEasy to use and safe PRODUCT DETAILSWelding metal Powder:We mix the powder comply with your conductor's material and size with reasonable ratio ,so the joint is more strong and more lasting.Tool box:We offer the full sets tools to meet your demand ,including ignition gun ,brush ,wrench ,screwdriver and glove . It is a package box to meet your whole demand. CHARACTERS l 1).Good current loading ability:The welding point current loading ability is same to that of conductor;l 2). Good mechanical performance:The connection is a molecular connection. It is a permanent connection ,no loss or corrosion result to high resistance;l 3). Stable dash current resistance:The test shows that in the surge of big current in short time, and the conductor melts earlier than the connection point, no damaged by surge current.l 4). Good resistance to corrosion:The welding joint is covered by copper and more strong than copper, it provides good resistance to corrosion.l 5). Simple and safe connection:Neither outside power nor facility is required. It take very little time to finish one welding both indoor and outdoor.l 6). Free control the reaction temperature: Different welding powder is provided according to the metal features, so the welding powder can be very solid. WELDING FLUX Welding metal Powderis also called aluminium heat welding powder.Use proper exothermic fluxes to make the connection joints more solid and extend the using life.

Ignite the propane torch and dry out the inside of the mold thoroughly on both sides, heating the mold .l Use a soft cotton cloth or a soft bristle brush to clean inside the mold cavity and coverl Check to ensure the graphite mold is not worn or broken, which could cause leakage of molten weld metal during the reaction.l The clamp is used for open-closing mould ,so the tightness of clamp is very important to the welding quality ,please carefully check and adjust the clamp before welding as following: (a)Keep the clamp open (b)Loosen the fixing buckle of clamp (c)Pick out gim peg (d)Adjust the regulating screw and contrarotate (Loosen ) (e)Pin the gim peg and buckle (f)Open clamp and check the resultl Close the grips to tightly lock the mold. Check for an appropriate seal on the mold.If the mold does not seal properly, make adjustments to tighten/loosen the handle clamp.l The mould is made of graphite and very gentle ,so don't throw or impact .Meanwhile the mold must be correct for the conductor size and application. Don't remove the residue with hard tooll If the conductor size is smaller than specified ,there will be copper liquid omitting .The following remedy for reference : (1)Use proper thickness copper pipe or copper bush (2)Use copper piece or copper tape (3)Use seal (4)Use Pyrocotton tapeOPERATION INSTRUCTION l Check to ensure the graphite mold and conductor is clean ,no residue before making the connectionl Use a propane torch to dry wire conductors and remove remaining cleaning residue, solvent, or water before making the connection.l Close the graphite mold lid before ignition ,and close the lid tightlyl Insert the conductors and position them for the connection.Ensure them in the center of cavity.l Keep the irrelevant personnel 1.5M away when weldingl Keep the inflammable goods 1-2M away when weldingl The operator must be equipped thermal barrier glovel Don't face to the mould opening when weldingl The operator keep 1.5M away mould is must after ignitionl Don't touch the mould and connected parts directly after weldingl Open the mould and take the joint out with wrench 10-20S later after reaction .l Insulate the joint after the conductor cooling completely .Company brief profileLonghui Plating Company is established in Oct 2013, and completed infrastructure in Dec 2014. The former company was Jinhua Li'an Electronic factory(Founded in Jan2010).Because of the government's policy of environment protection,we moved toLongyou County,Quzhou City from Jinhua city,and changed the company name toLongyou Longhui Plating Co.,Ltd.After moving to new place,we bought some advanced equipment,assembled 3product lines,capacity increase more than 5times. The whole factory covers an area of58.6 acres, investment amount of USD24,000,000 in first stage, the factory formallyput into operation in Mar 2015.To meet government's policy about environment protection,Longhui's brother company-Huaying was built in 2013.It's focus on managing plated waste water.After a series of treatment,the waste water can be directly discharged into sewer.There is no worry about be suspended to consolidate due to fail of government's environmental protection inspection every year,so that we could assure clients smoothly delivery time.Contact infos
