Care 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. The cylinders must be in a vertical position secured to a support or trolley.
Do not weld in areas where grease or paint are stored.
FIRE AND EXPLOSIONS RISKS
Protect the entire welding area. Compressed gas containers and other inflammable material must be moved to a
minimum safe distance of 11 meters.
A fire extinguisher must be readily available.
Be careful of spatter and sparks, even through cracks. It can be the source of a fire or an explosion.
Keep people, flammable objects and containers under pressure at a safe distance.
Welding of sealed containers or closed pipes should not be undertaken, and if opened, the operator must remove any inflammable
or explosive materials (oil, petrol, gas...).
Grinding operations should not be directed towards the device itself, the power supply or any flammable materials.
GAS BOTTLE
Gas leaking from the cylinder can lead to suffocation if present in high concentrations around the work area.
Transport must be done safely: Cylinders closed and product off. Always keep cylinders in an upright position
securely chained to a fixed support or trolley.
Close the bottle after any welding operation. Be wary of temperature changes or exposure to sunlight.
Cylinders should be located away from areas where they may be struck or subjected to physical damage.
Always keep gas bottles at a safe distance from arc welding or cutting operations, and any source of heat, sparks
or flames.
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.
ELECTRIC SAFETY
The machine must be connected to an earthed electrical supply. Use the recommended fuse size.
An electrical discharge can directly or indirectly cause serious or 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 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 in good condition, in order to be insulated from
the electrical circuit. Wear insulating shoes, regardless of the environment in which you work in.
EMC CLASSIFICATION
These Class A devices are not intended to be used on a residential site where the electric current is supplied by the
public network, with a low voltage power supply. There may be potential difficulties in ensuring electromagnetic
compatibility on these sites, because of the interferences, as well as radio frequencies.
MULTIWELD 250T-C / 320T-C / FV 220M-C :
This equipment complies with the IEC 61000-3-11 standard.
MULTIWELD 250T-C / 320T-C / FV 220M-C :
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 supply only at the medium- or high-voltage level. On a public low-voltage
power grid, it is the responsibility of the installer or user of the device to ensure, by checking with the operator
of the distribution network, which device can be connected.
ELECTROMAGNETIC INTERFERENCES
The electric currents flowing through a conductor cause electrical and magnetic fields (EMF). The welding current
generates an EMF field around the welding circuit and the welding equipment.
12
The EMF fields may disrupt some medical implants, such as pacemakers. Protection measures should be taken for people wearing
medical implants. For example, access restrictions for passers-by or an individual risk evaluation for the welders.
