Stray welding currents

Risk of injury due to stray welding currents!
Stray welding currents can destroy protective earth conductors, damage machines and
electronic devices and cause overheating of components, leading to fire.
•
Check that all welding current connections are firmly secured and electrical connections are
in perfect condition.
•
Set up, attach or suspend all conductive power source components such as casing,
transport vehicles and crane frames so they are insulated.
•
Do not place any other electronic devices such as drills or angle grinders on the power
source, transport vehicle or crane frames unless they are insulated.
•
Always put welding torches and electrode holders on an insulated surface when they are
not in use.
