Gas Cylinders; Electric Safety - ims PRO PULSEMIG 220 C Manual Del Usuario

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.

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.
Provided that the impedance of the low-voltage public electrical network at the common coupling point is less than Zmax =
0.349 Ohms, this equipment complies with IEC 61000-3-11 and can be connected to public low-voltage electrical mains. It is
the responsibility of the installer or user of the equipment to ensure, in consultation with the distribution netwtork operator if
necessary, that the network impedance complies with the impedance restrictions.
This equipment complies with the IEC 61000-3-12 standard.
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.
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.
All welders should take the following precautions in order to minimise exposure to the electromagnetic fields (EMF) generated by the welding circuit::
• position the welding cables together – if possible, attach them;
• keep your head and torso as far as possible from the welding circuit;
• never enroll the cables around your body;
• never position your body between the welding cables. Hold both welding cables on the same side of your body;
• connect the earth clamp as close as possible to the area being welded;
• do not work too close to, do not lean and do not sit on the welding machine
• do not weld when you're carrying the welding machine or its wire feeder.
