Note: Combined elements of Mn + Ni + Cr + Mo + V shall not exceed a total combined limits of 1.50 max.

Description:

DURAMAX E7024 electrode coverings contain large amounts of iron powder in combination with ingredients similar to those used in E6013 electrodes. The coverings on DM7024 are very think and usually amount to about 50% of the weight of the electrode, resulting in higher deposition efficiency. The DM7024 electrodes are well suited for making fillet welds in the flat or horizontal position. Weld face is slightly convex to flat, with a very smooth surface and a very fine ripple. These electrodes are characterized by a smooth, quiet arc, very low spatter, and low arc penetration. They can be used with high travel speeds. Electrodes of this classification can be operated on AC, DCEP or DCEN.
DM7024 is an excellent choice for earthmoving equipment, railroad cars, mining machinery, structurals, plate fabrication, shipbuilding, and mobile trailers.

RE-DRY CONDITIONS: Re-Dry the electrode at 250°C for one hour before use.

POLARITY: DCEP, DCEN or AC
DCEP: DC, Electrode Positive (reverse polarity) has the most weld penetration
DCEN: DC, Electrode Negative (straight polarity) has the least weld penetration
AC: medium weld penetration (can be more spatter)
WELDING POSITIONS: Flat, Horizontal, Overhead, Vertical-up and Vertical-down positions
USE LESS AMPS ON THIN METAL; MORE AMPS ON THICK METALS
