Notes on usage:
1. E.S.O. (Electrode Stick Out) must be kept between 15-25mm.
2. Proper welding conditions must be adopted according to the purpose as the bead appearance and penetration are both varied widely.
3. Use 100% Co2 or Ar + Co2 gas mixture as shielding gas.
4. Control within the optimal range of welding conditions for this wire as possible.
