CAUTION: Allow 15 seconds for mold cooling after the
reaction. This will permit the molten metal to solidify.
7. Carefully open the mold and remove the expended steel cup
— no special disposal required.
8. Break up the slag in the crucible using the blade on the
mold cleaning tool.
9. Unlock clamp and remove welder by pulling the mold straight
back from the rail. Failure to observe this may result in mold
damage and its premature scrapping. Molds can generally be
re-used up to 50 times.
10. Dump the slag from the crucible and remove the slag from
the taphole using the curved end of the mold cleaner. Dump
slag in the ballast, not onto the ties.
11. Check the molds for breakage or residual slag before
proceeding with the next weld.
