Operate extrusion presses to encase electric wire and cable in lead sheath.
What does a Lead Press Operator do?
Operates extrusion press to encase electric wire and cable in lead sheath: Bolts die in head of press, fills melting pot with lead, and mounts reel of cable on machine spindle. Threads cable through die and cooling chamber, fastens end to takeup reel, and starts machine. Adjusts controls to regulate speed of cable through machine, temperature and flow of metal, pressure of hydraulic ram, and pressure of water spray in cooling chamber to ensure uniform sheathing of lead on cable. Measures thickness and diameter of sheath with micrometers and calipers to verify conformity to size and surface specifications.
