| Characteristics | CM-90 is a low hydrogen type electrode for all-position welding, which provides the weld metal of 9%Cr-1%Mo. |
| Notes on usage | (1) Dry the electrodes at 325~375℃ for about one hour before use. (2) Preheat at 250~350℃ and posheat at 720~780℃. (3) Adopt back step method or strike the arc on a small steel plate prepared for this particular purpose to prevent blowholes at the arc starting. (4) Keep the arc as short as possible. |
