产品规格 Shielded metal arc welding (Stick electrode welding) is most broadly used in shipboard maintenance and repair welding. In welding two pieces of metal together, an electric arc is established the end of the coated electrode and the base metal in the joint. When the electric arc is struck between the tip of the electrode and the work piece (Base metal), molten droplets from the electrode are transferred to and mixed with the molten metal in the joint. As the arc progresses along the joint the molten weld metal cools and solidities forming a strong, integral bond in the joint. Arc welder converts shipboard power – usually 220, 380 or 440 volts, alternating currents (AC) to an output in the form of AC (Transformer) or DC (Rectifier) current. Typical welding currents may range from 30 to 400 amperes at voltage of 22 to 32 volts. Most electrodes used for shipboard maintenance welding operate at less than 200 amperes. So a current output of 400 amperes will suffice for most carbon arc applications. The output AC/DC type will be more flexible and better suited to a wide range of conditions. Please specify the following points when ordering: 1. Type of welder required; 1) Transformer (AC) 2) Rectifier (DC) 3) Transformer/Rectifier (AC/DC) 2. Main supply: Voltage and Frequency 3. Maximum output capacity: Current amperes
中文汉化 851051 弧焊机 电弧焊（棒极电极焊接）在船舶维修和焊接中最常用。当将两块金属焊接在一起时，会在带涂层电极的末端和接缝处的基材之间建立电弧。当电弧在电极尖端与工件（基材）之间点燃时，电极上的熔融液滴会转移到接缝处的熔化金属中并混合。随着电弧沿接缝移动，熔化的焊缝金属冷却并固化，形成接头处强大且连续的连接。弧焊机将船上的电源——通常为220伏、380伏或440伏交流电流（AC），转化为输出形式为交流（变压器）或直流（整流器）电流。典型的焊接电流范围可能在22到32伏电压下从30安培到400安培。船上维护焊接大多数使用的电极电流小于200安培。因此，400安培的电流输出足以满足大多数碳弧应用。输出的交流/直流类型将更加灵活，更适合各种条件。下单时请指定以下内容： 1. 需要的焊机类型； 1) 变压器（交流） 2) 整流器（直流） 3) 变压器/整流器（交流/直流） 2. 主电源：电压和频率 3. 最大输出容量：电流安培数
