可控硅直流弧焊电源,实质上是恒流电源,具有陡降特性,适合于一般的不熔化电极气体保护焊,例如氩弧焊,等离子焊。还可以作为等离子堆焊,等离子喷镀,等离子切割等方面的电源。本电源具有电流调节范围宽,电流稳定,并具有电流递增和衰减特性,所以特别适合于园形工件的等离子焊接。主要技术数据:交流输入:三相、280伏、50赫;电流调节范围:6～300安;自动稳定流范围:当电弧电压变化在10～40伏时,电流变化<3%;当网路电压变化范围在-15%到+10%时,电流变化<2%;暂载率50%;电流递增时间:1秒;电流衰减时间:3～15秒。
SCR DC arc welding power supply, in essence, constant current power supply, with steep drop characteristics, suitable for general non-melting electrode gas shielded welding, such as argon arc welding, plasma welding. Can also be used as plasma surfacing, plasma spraying, plasma cutting and other aspects of power. The power supply has a wide range of current regulation, current stability, and current increase and attenuation characteristics, it is particularly suitable for plasma welding park-shaped workpiece. The main technical data: AC input: three-phase, 280 V, 50 Hz; current adjustment range: 6 ~ 300 A; automatic stability of the flow range: when the arc voltage changes in 10 to 40 V, the current change <3% Current variation <2%; duty cycle 50%; current rise time 1 second; current decay time 3-15 seconds at -15% to + 10%.
