Fully unroll welding current leads, torch hose packages and intermediate hose packages. Avoid
loops!
Always keep leads as short as possible!
Lay any excess cable lengths in meanders.

Stray welding currents can destroy protective earth conductors, damage equipment and
electronic devices and cause overheating of components leading to fire.
• Make sure all welding leads are securely connected and check regularly.
• Always ensure a proper and secure electrical connection to the workpiece!
• Set up, attach or suspend all conductive power source components like casing, transport
vehicle and crane frames so they are insulated!
• Do not place any other electronic devices such as drillers or angle grinders, etc., 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!
