在水下焊接过程中，脉冲电源输出高电平时，停止送丝，电弧稳定燃烧并形成熔滴；
During the welding process, when underwater welding power outputs high level, the system stops feeding wires and wires burn upwards with forming molten droplets.
在停止送丝阶段，单片机令电源输出电压为峰值，焊丝在此电压下返烧并形成熔滴。
When the wire feed is pausing in each oscillating cycle, the output voltage of power source is a peak value and the wire is melted under the welding voltage, forming a droplet metal.
开始送丝后，焊接电源输出低电平，熔滴依靠送丝动量向熔池过渡。
When the wire being stopping, the welding power outputs high level voltage with wire burning back and forming a liquid weld metal drop.
