  • Caution ① The preheat temperatures vary in accordance with the size, kind and shape of the base metal. 150℃(302℉) is appropriate in general.

    ② Gradual cooling recommended after welding

    ③ Keep the weld metal length less than 50mm(2 inch) to disperse welding heat. Adopt back stepping stone or symmetry method by turns.
  • Purpose ① Repairing of cast iron
  • Attribute ① Machining impossible (As welded)

    ② Easy to remove slag

    ③ Preheat at 200~350°C (392~662°F)

    ④ Stable arc and good bead appearance
