产品特点

1、三相输入：和单相输入的交流埋弧焊电源相比，输入电流小，三相平衡，功率因数高，对电网容量要求低，而且比单相交流埋弧焊电源节能20%。

2、熔敷率高：通过调节方波占宽比，焊丝熔敷率可比直流埋弧焊机最大提高59%，极大提高焊接效率。

3、无磁偏吹：由于采用交流方波输出， 电弧稳定，焊缝成形美观，不易产生焊接缺陷。

4、极性切换方便：直流焊接时可一健切换焊机输出极性，无需重新连接焊接电缆。

5、可用于单丝、双丝及多丝埋弧焊、带极堆焊、窄间隙埋弧焊、手工电弧焊。

6、额定负载持续率高:在输出1250A额定电流的情况下，负载持续率高达100%。

7、风机节电技术：焊接完成后，风机吹冷焊机后自动停转。重新启动焊接时又开始运行。

Product Features

1. Three phase input: Compared with single-phase input AC submerged arc welding power sources, the input current is smaller, the three phases are balanced, the power factor is higher, the requirements for grid capacity are lower, and it saves 20% energy compared to single-phase AC submerged arc welding power sources.

2. High deposition rate: By adjusting the square wave width ratio, the deposition rate of welding wire can be increased by up to 59% compared to DC submerged arc welding machine, greatly improving welding efficiency.

3. Non magnetic bias blowing: Due to the use of AC square wave output, the arc is stable, the weld seam is aesthetically pleasing, and welding defects are less likely to occur.

4. Convenient polarity switching: During DC welding, the output polarity of the welding machine can be easily switched without the need to reconnect the welding cable.

5. Can be used for single wire, double wire, and multi wire submerged arc welding, strip welding, narrow gap submerged arc welding, and manual arc welding.

6. High rated load duration: With an output of 1250A rated current, the load duration can reach up to 100%.

7. Fan energy-saving technology: After welding is completed, the fan automatically stops running after blowing the cold welding machine. When restarting the welding process, it starts running again.
