我局水电安装队技师马玉琢创造成一部铁丝电阻电焊机(本刊8期跃进消息已有报导——编者按)。这种电焊机结构非常简便,制造方便,功率大,使用效果比水阻电焊机好,完全可以代替弧焊机。制造时,用25×25×4公厘角铁作支架,用低压茶台瓷瓶每台40个分为四串作为绝缘支持物。电阻丝是用8号镀锌铁丝100公尺,作成盘簧式,外径为27公厘,间距10公厘,每一路上下悬挂10挡(高度70公分)。铁架底角用低压3号直立磁瓶四个作为绝缘。机身外围 I hydroelectric installation team technician Ma Yuzhuo into a wire resistance welding machine (Newspaper 8 Yuejin news has been reported - Editor’s Note). This welding machine structure is very simple, easy to manufacture, power, the use of water resistance than the welder, can replace the arc welder. Manufacture, with 25 × 25 × 4 mm angle iron as a stent, each with a low-pressure tea table porcelain 40 is divided into four strings as insulation support. Resistance wire is galvanized wire No. 8 100 meters, made of coil spring, the outer diameter of 27 mm, spacing 10 mm, each hanging from top to bottom 10 (height 70 cm). Iron bottom corners with low pressure 3 upright magnetic bottle four as insulation. Body periphery
