2. Welding power leads
- must be kept as short as possible
- must run close together (to avoid EMF problems)
- must be kept well apart from other leads
3. Equipotential bonding
4. Earthing of the workpiece
- If necessary, establish an earth connection using suitable capacitors.
5. Shielding, if necessary
- Shield off other nearby devices
- Shield off entire welding installation
Electromagnetic fields may pose as yet unknown risks to health:
- effects on the health of others in the vicinity, e.g. wearers of pacemakers
and hearing aids
- wearers of pacemakers must seek advice from their doctor before ap-
proaching the device or any welding that is in progress
- for safety reasons, keep distances between the welding cables and the
welder's head/torso as large as possible
- do not carry welding cables and hosepacks over the shoulders or wind
them around any part of the body
The following requirements with regard to shielding gas quality must be met if
the welding system is to operate in a correct and safe manner:
- Size of solid matter particles < 40 μm
- Pressure dew point < -20 °C
- Max. oil content < 25 mg/m³
Filters must be used if necessary.
NOTE! There is an increased risk of soiling if ring mains are being
used
Shielding gas cylinders contain gas under pressure and can explode if dam-
aged. As the shielding gas cylinders are part of the welding equipment, they
must be handled with the greatest of care.
Protect shielding gas cylinders containing compressed gas from excessive
heat, mechanical impact, slag, naked flames, sparks and arcs.
Mount the shielding gas cylinders vertically and secure according to instruc-
tions to prevent them falling over.
Keep the shielding gas cylinders well away from any welding or other electrical
circuits.
Never hang a welding torch on a shielding gas cylinder.
Never touch a shielding gas cylinder with an electrode.
Risk of explosion - never attempt to weld a pressurised shielding gas cylinder.
Only use shielding gas cylinders suitable for the application in hand, along with
the correct and appropriate accessories (regulator, hoses and fittings). Only
use shielding gas cylinders and accessories that are in good condition.
Turn your face to one side when opening the valve of a shielding gas cylinder.
Close the shielding gas cylinder valve if no welding is taking place.
