Type of Current: Direct Current Electrode Positive (DCEP) or AC
Recommended Welding Techniques:
- Arc Length: Less than half the diameter of the electrode
- Flat: Angle electrode 10 – 15 from 90
- Horizontal: Angle electrode slightly toward top plate
- Vertical-Up: Use weaving technique
- Vertical-Down: Not recommended
- Overhead: Use slight weaving motion within puddle
- Storage: To ensure a low hydrogen weld deposit, storage in an oven at 220F to 350F (104C to 117C) is recommended.
- Reconditioning: If exposed to atmosphere for extended periods, the electrode should be reconditioned for one hour at 575F (302C).
