welding rod Mild Steel Electrodes Description:E6013 is of low mild type electrodes with titanium coating and suitable for both AC and DC.It can weld in all position. Manipulates is free and restrike is easy. Application: Used to weld low carbon steel structures,especially suitable for welding thin flat,intermittent shorter welds, as well as some smooth appearance cover.

In case of moisture, dry the electrode at 70-100oC for 30 60 mimutes before use. AWS E7018 Mild Steel Electrodes Description:E7018 is an excellent carbon steel electrode with iron powder low hydrogen potassium coating.It is used on both AC AND DC in all position.As the coating contains iron powder, it has highly efficient welding and can reduce welding layers. Application:Used to weld low carbon structure and low alloy steel structure,such as 16Mn etc. CHEMICAL COMPOSITIN OF MELTING METAL(%) C Mn Si S P ≤0.12 ≤1.60 ≤0.75 ≤0.035 ≤0.040 Reference Current Diameter(mm) 2.53.2 4.0 5.0 Current 90 120 120 150 170 200 210 250 Noto: Before welding, it is necessary to clean the work piece and remove the impurities such as oil, grease rust and moisture,bake the electrode at the temperature of about 350 degree centigrade for one hour.The welding must be carried out under short arc and is suitable for narrow path.When used DC,the electrode must be connected with positive polarity.
