Storage储存：Electrodes should be stored in dry conditions. Should the electrodes  become damp, re-dry for one hour at 150°C before use. 焊条应储存在干燥环境中。如果焊条受潮，应在150°C下重新干燥1小时后再使用。  

使用注意事项：

For best results when using this rod try to keep the arc length as short as possible and keep the weave tight. Put simply keep the bead bbbbb within 2.5 times of diameter of the core wire.

为了获得理想效果，在使用这种焊条时，尽量保持弧长尽可能短，并保持编织紧密。简单地说，将焊道宽度保持在焊芯直径的2.5倍以内。
