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 spatter and sparks, even through cracks. It can be the source of fire or explosion.
Keep people, flammable materials/objects and containers 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 cylinder valve, it is necessary to remove the tip of the valve and make sure that the gas meets your welding requirements.
ELECTRICAL SAFETY
The electrical mains used must have an earth terminal. Use the recommended fuse size.
An electrical shock can directly or indirectly cause serious and potentially deadly accidents.
Do not touch any live part of the machine (inside or outside) when it is plugged in (torches, clamps, 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 authorised person.
Make sure that the cable cross section (extension lead and welding cables) is in accordance with the application.
Always wear dry clothes which are in good condition in order to be isolated from the welding circuit. Wear insulating shoes, regardless of the
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.
EMC CLASSIFICATION
This Class A machine is not intended to be used on a residential site where the electric current is supplied by the domestic
low-voltage power grid. There may be potential difficulties in ensuring electromagnetic compatibility at these sites, due to
conducted interferences as well as radiation.
This equipment does not comply with IEC 61000-3-12 and is intended to be connected to private low-voltage systems interfacing
with the public power grid only at the medium- or high-voltage level. If it is connected to a public low-voltage power grid, the
installer or user of the machine has to ensure, by checking with the operator of the distribution network, that the device can
be connected.
This equipment complies with the IEC 61000-3-11 standard.
