VR-315/400/500

性能特點
1、采用的軟開關逆變技術，以進口IGBT和微晶磁芯為核心配件
2、負載持續率高，設有引弧電流和電流推力調節功能
3、具有電壓波動自動補償功能，電弧穩定，熔池均勻，飛濺少，焊縫成型美觀
4、電路板采用進口絕緣脂QC膠，真空封灌，防止灰塵
5、風機采用隔離式結構，以防雨水進入;
6、節電設計，五秒間隔不起弧，自動切斷主電路電源，安全可靠。

用途
1、非常用于礦山、煤礦井下380V及660V電源場合作業。
2、適用于碳鋼、合金鋼、鑄鐵、不銹鋼、銅及合金的焊接。本機如配接觸式氬弧焊槍，即可用于接觸式氬弧焊。

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
