5.1.6  Stray welding currents 

 

 

 WARNING 

 

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, trans-

port 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.
