一种可望取代我国现普遍使用的夹钳式电焊钳的DJ型全绝缘式节能电焊钳,最近由浙江省瓯海县巨溪恒力机械工具厂研制成功,通过了轻工部工具五金质量监督检测中心的鉴定。这种新型电焊钳与夹钳式电焊钳相比,具有以下优点:重量、体积仅为后者的一半,操作灵便,可大大减轻工人的劳动强度;结构为全封闭绝缘式,使用时不会产生二处起弧事故,焊条夹持拉力为后者的两倍,安全可靠;电缆接角电阻比后者小一半以上,因而省电,升温低,利于连续焊接,提高工效;耐电弧性能及抗冲击力强,另件各部位不易老化损坏,使用寿命较后者高一倍以上,而价格略低。特别适合于高空、罐体容器、管道 A kind of DJ type full-insulated energy-saving welding clamp which is expected to replace the clamp clamp welding torch widely used in our country recently was successfully developed by Juxi Hengli Machinery Tools Factory in Ouhai County of Zhejiang Province and passed the hardware quality Supervision and Testing Center of identification. Compared with the clamp-type welding clamp, this new type of welding clamp has the following advantages: the weight and volume are only half of the latter, the operation is flexible, which can greatly reduce the labor intensity of workers; the structure is fully enclosed and insulated and can not be used Resulting in two arcing accidents, the electrode clamping tension for the latter two times, safe and reliable; cable connection angle resistance than the latter more than half, so power, low temperature, conducive to continuous welding, to improve work efficiency; arc resistance and Impact resistance, the other parts of the aging damage is not easy, the service life more than double the latter, while the price is slightly lower. Particularly suitable for high altitude, tank containers, pipes
