LT·J507 2.0/2.5/3.2/4.0/5.0 mm Carbon Steel Electrodes
E7015 welding electrode is a kind of carbon steel electrode with low-hydrogen natrium type coating. DCRP (Direct Current Reversed Polarity). All-position welding. It has excellent welding performance, stable arc, fewer spatters and good slag detachability. The deposited metal has excellent mechanical properties, crack-resistance and low temperature impact roughness.

Notes:
1. The electrode must be preheated at the temperature of 350°C for 1 hour. Preheat the rod whenever it is used.
2. The impurities such as rust, oil stains and moisture must be cleared off of the work piece.
3. Short arc is required to perform welding. Narrow weld path is preferred.
