VR-315/400/500
性能特点
1、采用先进的软开关逆变技术，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、风机采用隔离式结构，以防雨水进入;
6、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、非常用于矿山、煤矿井下380V及660V电源场合作业。
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 adiustment 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 of 5 seconds, it will cut off the power of the main circuit to ensure safety and reliability
Functions
It is applied very well in the work site of 660V and 380V dual-purpose power operations in mines and coal mine undergroung
Applincable for the welding for carbon steel, alloy steel, cast iron, stainless steel, copper and alloy, When equipped with contact argon arc Welding gun the machine can be used in contact argon arc welding
