Mac Trode E6918-G
AWS E9018-G
Descriptions & Applications:
This is a low hydrogen electrode using a free, low nitrogen, high purity C:Mn core wire with a concentrically extruded, moisture resistant chemically basic flux with a controlled iron powder addition. It is an easy to use electrode for welding in all positions. Good restriking ability and smooth, easy flowing welds. Pre-heat & interpass temperatures 100°C min. and up to 200°C for thick sections.
