UN1-75(LP-75)对焊机存在两大缺点:一是机床刚性不够,电极的两个支承架直接装在用角铁焊接的床体上,当对焊时由于受力使机床变形,使两个V形电极中心线不平行,对焊出的零件不直(弯曲);二是两个电极靠斜面调整高低位置,所以焊渣经常掉在电极上或者氧化物使电极斜面接触不良,需要经常清理,给维修工人造成很大麻烦。为此我厂于1966年对
UN1-75 (LP-75) on the welding machine there are two major shortcomings: First, the machine rigidity is not enough, the two electrode support frame mounted directly on the body with angle iron welding, when the welding force due to deformation of the machine , So that the two V-shaped electrode center line is not parallel to the welded parts out of the straight (curved); Second, the two electrodes by the slope adjustment height position, so the slag often fall on the electrode or the oxide electrode slope poor contact , Need to be cleaned regularly, causing great troubles to maintenance workers. To this end I plant in 1966 right
