WELDING FUMES AND GAS
Fumes, gas and dust produced during welding are hazardous to health. It is mandatory to ensure ade-
quate ventilation and/or extraction to keep fumes and gas away from the work area. Using an air fed
welding helmet is recommended in case of insufficient ventilation in the workplace.
Check that the air supply is effective by referring to the recommended safety regulations.
Precautions must be taken when welding in small areas, and the operator will need supervision from a safe distance.
Welding certain pieces of metal containing lead, cadmium, zinc, mercury or beryllium can be extremely toxic. The user
will also need to degrease the workpiece before welding.
Gas cylinders must be stored in an open or ventilated area. They must be stored vertically and held by a support or
trolley to limit the risk of falling. Do not weld in areas where grease or paint are stored.
FIRE AND EXPLOSION HAZARDS
Protect the entire welding area. Flammable materials must be moved to a minimum safe distance of 11
meters.
A fire extinguisher must be readily available near the welding operations.
Be careful of weld spatter and sparks, even through cracks. If not careful then this could potentially lead to a fire or an
explosion.
Keep people, flammable materials/objects and containers that are under pressure at a safe distance.
Welding in closed containers or pipes should be avoided and , if they are opened, they must be emptied of any
flammable or explosive material (oil, fuel, gas ...).
Grinding operations should not be carried out close to the power supply or any flammable materials.
GAS CYLINDERS
Gas leaking from the cylinders can lead to suffocation if present in high concentration around the work
area (ventilation required).
Transport must be done safely: cylinders closed and welding machine switched off. They must be
stored vertically and held by a support to limit the risk of falling.
Close the cylinder between two uses. Beware of temperature variations and sun exposure.
The cylinder must not be in contact with a flame, electric arc, torch, earth clamp or all other sources
of heat.
Always keep gas cylinders away from electrical circuits, and therefore never weld a cylinder under
pressure.
Be careful when opening the valve on the gas bottle, it is necessary to remove the tip of the valve and
make sure the gas meets your welding requirements.
ELECTRICAL SAFETY
The electrical mains used must have an earth terminal. Use the recommended fuse size.
An electric shock could cause serious injuries or potentially even deadly accidents.
Do not touch any live part of the machine (inside or outside) when it is plugged in (Torches, earth cable, cables,
electrodes) because they are connected to the welding circuit.
Before opening the device, it is imperative to disconnect it from the mains and wait 2 minutes, so that all the capacitors
are discharged.
Do not touch the torch or electrode holder and the earth clamp at the same time.
Damaged cables and torches must be changed by a qualified and skilled professional. Make sure that the cable cross
section is adequate with the usage (extensions and welding cables). Always wear dry clothes which are in good condition
in order to be isolated from the welding circuit. Wear insulated shoes, regardless of the workplace/environment in which
you work in.
