Safety specifications for MIG/MAG welding machines
1 = Welding power source, 2 = Electric tool,
3 = Workpiece 1, 4 = Workpiece 2
The welding current flows via the protective conductors of the two electric
tools, if by mistake welding takes place on tool 4 without having changed
connections (earth) of the welding current return line from workpiece 3 to
workpiece 4 .
The protective conductor in the mains cable and in the building installation
are hereby destroyed.
If possible, use a potential compensating line with a high cross-section!
Please observe the following points to prevent stray currents.
• Fasten workpiece clamp as close as possible to the welding spot.
• Please take care that the torch not in use is stored with a sufficient insula-
tion.
• Please take care that the torch not in use is protected against unintended
triggering of the start command.
• Switch off welding equipment which is not in use to avoid electric acci-
dents.
