High-Deposition Welding
High deposition applications includes groove, fillet, lap and corner welds in 3/16” and thicker plate welded with the work level or slightly downhill. These joints are capable of holding a large molten pool of weld metal as it freezes.
These welds are made with Jetweld electrodes because the high iron powder content in the coating produces high deposit rates to fill joints in the shortest time for economical welding.

Alternate Electrodes
When desired, the following alternate electrodes can be used with similar procedures:
Recommended | Alternate |

Jetweld Operating Techniques
Polarity and Current – Use AC for fast welding speeds, high deposit rates, and good arc characteristics. DC can be used but the resulting arc blow may complicate control of the molten puddle.
Optimum current for most jobs is
Use a Drag Technique – Tip the electrode 10 to 30° in the direc- tion of travel and make stringer beads. Weld with the electrode end lightly dragging on the work to force the molten metal out from under the electrode tip allowing adequate penetration. The smooth welds look almost like automatic welds.
