什么是脉冲电源? 大多数电弧焊电源的设计使得电能输出较为稳定,用于各种焊接方法时,可焊出满意的焊缝。对于涂料焊条手工焊或非熔化极气体保护焊,采用基本上是恒定电流输出的电源,而对于熔化极气体保护焊或埋弧焊,用恒定电压电源较易控制焊接过程。输出无脉动是旋转式焊接电源的特有之处。变压器——整流电源的缺点是输出脉动大,一般刚能限制在许可范围内。较昂贵的电源依靠接有滤波网路消除脉动,设计复杂一些的电 What is the pulse power? Most of the arc welding power supply design makes the power output is more stable, for a variety of welding methods, welding out satisfactory welds. For the coating electrode manual welding or non-melting gas welding, the use of a substantially constant current output of the power supply, and for the welding gas arc welding or submerged arc welding, constant voltage power supply easier to control the welding process. Pulse-free output is unique to rotary welding power supplies. Transformer - The disadvantage of the rectified power supply is that the output pulsation is large and can generally be limited within the permitted range. The more expensive power supply relies on the filter network to eliminate pulsation, the design of a number of complex electrical
