电焊机是现代工业重要的工艺装备，已广泛应用于冶金、建筑、机械、汽车、轻工、电力等不同领域。然而爬墙式电焊机在作业过程中意外断电时，从空坠落，造成严重不安全事故。该文第二代移动升降式电焊机采用多级伸缩式气缸作为升降系统，可对高为0～4.5m的三维空间结构实施焊接，从根本上解决了第一代爬墙式电焊机作业过程中不安全的弊端。此外，对气缸进行计算、校核工作过程分析以及防尘结构的创新设计，提高了升降式电焊机的可靠性和使用寿命，从而保证了电焊机安全、高效的工作。

Electric welder is one of the most important technological devices in modern industry and has been applied in diverse kinds of fields including metallurgy, construction, machinery, automobile, light industry, electric power etc. However, electric welder with climbing type will fall and lead to serious security incidents when interrpution of power supply occur. In this paper, electric welder with elevator type, the second generation welder using multi-telescopic cylinder as the lifting system, can safely accomplish welding in three-dimensional space with the height ranging from 0 to 4.5 metre and avoids the deffects appearing in electric welder with climbing type radically. Moreover, com-putation, verification and creative design in dustproof structure can enhance the reliability and lifetime in electric welder with elevator type in order that safety and high efficiency enssured in electric welder work.
