| DC-315/400/500 
性能特点
1、采用的软开关逆变技术，以进口IGBT和微晶磁芯为核心配件
2、负载持续率高，设有引弧电流和电流推力调节功能
3、具有电压波动自动补偿功能，电弧稳定，熔池均匀，飞溅少，焊缝成型美观
4、电路板采用进口绝缘脂QC胶，真空封灌，防止灰尘
5、节电设计，五秒间隔不起弧，自动切断主电路电源，安全可靠 用途
1、可以利用矿井电机车直流架线电源进行轨道、管道、矿车等焊接。使用时将焊机的电源引线直线上一搭即可烧焊，使用十分方便
2、适用于碳钢、合金钢、铸铁、不锈钢、铜及合金的焊接。本机如配接触式氩弧焊枪，即可用于接触式氩弧焊。 Performance
Adopt advanced soft swich inverting technology;take the imported IGBT and micro-crystalline magnetic core focus fittings
A high load duration rate;striking arc current and current push adjustment function are equipped
Bear voltage fluctuation automatic compensation function, stable electric arc, evenm olten pool, little splash and beautiful welding line;
The circuit board adopts imported insulating resin QC glue and the vacuity sealed design can prevent dust
The air blower adopts isolated structure to prevent rain water
With energy-saving design, if it can not do arc start at the interval ot 5 seconds, it will cut off the power of the main circuit to ensure satety and reliability Functions
It can be used to weld the orbit, pipeline and mine car by adopting the DC power ge nerated by the mine electric locomotive. It can be conveniently operated by contacting the power source lead wire with the DC wire to begin welding
Applincable for the welding for carbon steel, alloy steel, cast iron, stainless steel, cop per and alloy, When equipped with contact argon arc welding gun, the machine can be used in contact argon arc welding | 产品型号 Product model | DC-315 | DC-400 | DC-500 | | 电源电压（V） Power supply（V） | 直流（DC）250V或550V | | 额定输入电源容量（KVA） Rated input power capacity（KVA） | 13 | 18 | 25 | | 空载电压（V） No load voltage（V） | 74±5 | 74±5 | 74±5 | | 电流调节范围（A） Current adjustment scope（A） | 20~315 | 20~400 | 20~500 | | 负载持续率（%） Rated duty cycle（%） | 60 | 60 | 60 | | 重量（kg） Weight（kg） | 35 | 38 | 40 | | 外形尺寸：长×宽×高（mm） External size：L×W×H（mm） | 645×325×585 | | |
