Safety requirements for welding cables
2013-09-03 by xiugai
welding cable should have good electrical conductivity and insulating outer layer , general welding copper ( multi-strand thin ) line, outsourcing insulating sleeve made ​​of rubber , insulation resistance of not less than 1MΩ. 2 soft, lightweight , can be any bending and torsional easy to operate. 3 welding cables should have good mechanical damage ability , oil, heat and corrosion resistance properties. 4 welding cable length should be determined depending on the circumstances , the voltage increases too big , too short for working inconvenient, generally take 20-30 m cable length . 5 have appropriate cross-sectional area , welding cable cross-sectional area should be based on the size of Tungsten Welding Electrodes current , selected according to the provisions in order to ensure wires from overheating and burning insulation. 6 welding cable applications in the middle of the whole root there should be joint, take a long time for a short-term , the joint should not exceed two connectors made ​​of copper , to be strong and reliable good insulation . 7 prohibit the use of metal construction factory operators , pipes or other metal wire used as a lap together . 8 welding cables shall not be placed on or near electric hot side of the weld metal to avoid burn insulation layer , while avoiding rolling wear. 9 welder welding cable and wiring must be copper or lead line the nose , in order to avoid secondary terminal board burn cause a fire. 10 welding cable insulation should be checked every six months . 11 welder and power strips connected to power lines, due to high voltage, in addition to ensure good insulation , but its length should not exceed 3m, if it proves necessary long lead time , safety measures should be taken to the interval , which should from the ground 2.5 m or more along the wall with porcelain cloth laying, laying along the power cord is strictly prohibited , not to fall into the mud .
