Safety and Scheduled Maintenance Protect Your Welding Assets
Q: What can I do to avoid electrical shocks?
A: Wet working conditions must be avoided, because water is an excellent
conductor and electricity will always follow the path of least resistance. Even
a person's perspiration can lower the body's resistance to electrical shock.
Poor connections and bare spots on cables further increase the possibility of
electrical shock, and therefore, daily inspection of these items is
recommended. Equipment operators should also routinely inspect for proper
ground connections.
