天津市电焊机厂广大革命职工在党的“九大”精神鼓舞下,去年试制成 GM—1000型自动氩弧焊机。此焊机可以代替苏修氩弧、埋弧的二种焊机,在抛帝甩修的道路上迈进了一大步。GM—1000型自动弧焊机的电源部份由硅整流元件组成。焊车的速度及送丝速度均采用可控硅进行控制,其中送丝速度由电弧电压反馈控制。该焊机可以对8—40毫米铝、铜、
The vast number of revolutionary workers in Tianjin Electric Welder Factory, encouraged by the spirit of “the 9th National Congress of the CPC”, made trial production of GM-1000 automatic argon arc welding machine last year. This welding machine can replace the Su-repair argon arc, submerged arc welding of two kinds, in the process of throwing the emperor to shake off a major step forward. GM-1000 automatic arc welding power supply part of the silicon rectifier components. Welding speed and wire feeding speed are controlled by silicon controlled rectifier, in which wire feeding speed is controlled by arc voltage feedback. The welder can 8-40 mm aluminum, copper,
