FIRE AND EXPLOSION RISKS

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 spatter and sparks, even through cracks. It can be the source of fire or 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.

Ensure that cables and torches are replaced by a qualified and authorised person if they are damaged. 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 insulating shoes, regardless of the workplace/environment in which you work in.

INSTALLATION OF THE REEL AND LOADING OF THE WIRE

 Isolation of the welder at the arc in relation to the welding voltage !

Not all the different parts involved in the welding current can be protected against direct human contact. The welder must therefore avoid the risks 

by following the relevant safety regulations. Even a contact at low current may take the operator by surprise and cause an incident.

- Wear dry and intact protective equipment (shoes with rubber soles/baked welder’s protective gloves without rivets or staples)!

- Avoid direct contact with non-insulated or connecting sockets!

- Always place the welding torch or electrode holder on an insulated support!

 Risk of burns where the welding current is connected!

If the connectors are not safely locked in place, the connectors and the cables may become hot and cause burns !

• Check the welding connectors daily and lock them in place if needed by turning them clockwise.

 Risk of electrocution !

If the weld is performed using different processes while the torch and the electrode holder are connected to material, a no-load voltage or welding 

voltage is applied to the circuits ! 

At the beginning of a job and during interruptions, always isolate the torch and the electrode holder !

ELECTRO-MAGNETIC EMISSIONS

The electric current flowing through any conductor causes electrical and magnetic fields (EMF). The welding current generates an 

EMF around the welding circuit and the welding equipment.

The EMF electromagnetic fields can interfere with certain medical implants, such as pacemakers. Protective measures must be taken for people having 

medical implants. For example, by restricting access to passers-by or conducting an individual risk evaluation for the welders.
