Supratherme (Spl) Mod is a basic coated iron powder type, high yield, and hydrogen- controlled electrode. Easy to operate in all conventional welding positions. Radiographic quality welds having excellent cracking resistance. Ideally suited for welding carbon steels used in the construction of equipment subjected to heavy dynamic load, impact, and severe service conditions in sour gas service.
1. Ensure the electrodes are dry. Re-dry the electrodes at 300°C for one hour.
2. Use short are, minimize heat input.
