Helvi AUTOFEED 450 Manuel D'instruction page 13

Power cables, extension leads and welding cables must be fully uncoiled to prevent overheating.
- Check that the metal piece is strongly held and without any electrical problems !
- Attach or hang all the electrically conductive elements,such as the trolley in order to insulate them
- Do not place any non-insulated electrical equipment such as drills on top of the welding machine or its trolley !
- Always place welding torches or electrodes holders on an insulated surface when they're not in use !
ELECTROMAGNETIC 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 may disrupt some medical implants, such as pacemakers. Protection measures must be taken for people using medical implants. For
example, by restricting access to poeple passing by or conducting an individual risk evaluation for the operators.
All welders should follow the instructions below 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 upper body 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 welding area;
• do not work too close to, do not lean on and do not sit on the welding machine
• do not weld when you're carrying the welding machine or its wire feeder.
People wearing pacemakers are advised to consult a doctor before using this device.
Exposure to electromagnetic fields while welding may have other health effects which are not yet identified.
TRANSPORT AND TRANSIT OF THE WIRE FEEDER
The wire feeder can be carried using the handle. Be careful not to underestimate the weight of the machine. The handle cannot be used to hang or
attach the machine on something else. Never lift the machine while there is a gas bottle on the support shelf. The transport rules applying to each
item are different.
Do not carry the unit over people or objects. The removal of the wire reel from the machine is recommended before undertaking any lifting operation.
INSTALLATION
Rules to follow :
• Make sure all the access panels are shut when switching the wire feeder on.
• Put the wire feeder on a floor with a maximum incline of 10°.
• The machine must be placed in a sheltered area away from rain or direct sunlight.
• The equipment's protection level is IP23, which means :
- Protection against acess to dangerous parts from solid bodies of a ≥12.5mm diameter and,
- Protection against the rain inclined at 60° towards the vertical.
The equipment can be used outside in accordance with the IP23 protection certification.
The manufacturer does not accept any liability in relation to damage or harm to objects or people due to an incorrect or careless
use of the equipment.
MAINTENANCE / RECOMMENDATIONS
• Maintenance should only be carried out by a qualified person. A yearly maintenance is recommended.
• Ensure the wire feeder is disconnected from the welding machine, and wait for two minutes before carrying out
maintenance work.
• Remove the casing 2 or 3 times a year and blow any excess dust out. Take this opportunity to have the electrical connections checked by a qualified
person, using an insulated tool.
• Regularly check the condition of the connection cable between the wire feeder and the machine. If found damaged, the interconnection cable must
be replaced.
• Warning ! If the welding machine is transported/handled by another solution than the one recommended by the manufacturer; the wire feeder
casing must be insulated from the transporting/handling solution.
