EQUIPMENT FOR RESISTANCE WELDING FOR INDUSTRIAL AND
PROFESSIONAL USE.
Note:Inthefollowingtexttheterm“spotwelder”willbeused.
1.GENERALSAFETYRULESFORRESISTANCEWELDING
The operator must receive full instructions regarding safe use of the spot welder
and must be informed of the risks related to resistance welding procedures, as
well as the related safety measures and emergency procedures.
The spot welder (only in the versions with pneumatic cylinder operation) is
equippedwithamainswitch,thatcanbelockedatposition“O”(open),with
emergency functions.
The lock key can only be given to operators who are expert or have been trained
on the duties assigned to them and on the possible dangers deriving from this
welding procedure or from the negligent use of the spot welder.
Whennooperatorispresenttheswitchmustbemovedtoposition“O”,locked,
and the key must be removed from the lock.
- Electrical installation must comply with health and safety legislations and
standards.
- The spot welder must be connected only and exclusively to a power supply
with the neutral conductor connected to earth.
- The power supply outlet must be correctly connected to the earth conductor.
- Do not use cables with worn insulation or loose connections.
- Usethespotwelderinanambientairtemperaturerangingfrom5°Cto40°C,
withrelativehumidityequalto50%uptoatemperatureof40°C,and90%for
temperaturesupto20°C.
- Do not use the spot welder in damp or wet conditions or under the rain.
- The connection of the welding cables and any routine maintenance
operations on the arms and/or electrodes must be carried out with the spot
welder switched off and disconnected from the electric and pneumatic (if
present) power supply networks.
The same procedure must be respected when connecting to the hydraulic
network or a closed circuit cooling unit (water cooled spot welders) and
whenever repairs (extraordinary maintenance) are carried out.
- Whenusingspotweldersoperatedwithpneumaticcylinder,themainswitch
mustbelockedat“O”usingthesuppliedlock.
The same procedure must be respected when connecting to the hydraulic
network or a closed circuit cooling unit (water cooled spot welders) and
whenever repairs (extraordinary maintenance) are carried out.
- It is forbidden to use the equipment in environments comprising areas
classed as being at risk of explosion because of the presence of gas, dust or
mist.
- Do not weld containers, receptacles or piping that contain or have contained
ammableliquidsorgases.
- Do not work on materials cleaned with chlorinated solvents or in the vicinity
of such substances.
- Do not weld containers under pressure.
- Remove all ammable substances (e.g. wood, paper, rags etc.) from the
working area.
- Allownewly-weldedpiecestocool!Donotleavethepiecenearammable
substances.
- Make sure there is an adequate air exchange or means suitable for removing
the welding smoke near the electrodes; a systematic approach for evaluating
the welding smoke exposure limits according to composition, concentration
and exposure duration is necessary.
- Always wear suitable protection glasses.
- Wear protection gloves and clothing that is suitable for working with
resistance welding machines.
- Noise level: If particularly intensive welding operations lead to a daily
personal noise exposure (LEP,d) of 85dB(A) or more, the use of suitable
personal protection equipment is obligatory.
- Thepassageof the spotwelding currentgenerates electromagneticelds
(EMF) around the spot welding circuit.
The electromagnetic elds can interfere with some medical equipment (e.g.
Pace-makers, respirators, metal prostheses, etc.).
Suitable measures must be taken to protect those who use this equipment. As
an example, prohibit access to the spot welder use area.
This spot welder complies with the requirements of the technical standard for
products to be used only and exclusively in industrial environments and for
professional purposes. Correspondence with the basic limits regarding human
exposuretoelectromagneticeldsinadomesticenvironmentisnotguaranteed.
The operator must follow the procedures given below in order to reduce
exposuretoelectromagneticelds:
- Fix the two spotting cables (if present) as near to each other as possible.
- Operators must keep their heads and trunks as far away as possible from the
spotting circuit.
- Operators must never wind the spotting cables (if present) around their body.
- Operators must not spot weld with their body in the middle of the spotting
circuit. Operators must keep both cables on the same side of their body.
- Connect the spot welding current return cable (if present) to the piece to be
welded,ascloseaspossibletothejoinbeingmade.
- Never spot weld near, sitting on, or leaning against the spot welder (minimum
distance:50cm).
- Donotleaveferromagneticobjectsnearthespotweldingcircuit.
- Minimumdistance:
-d=40cm(FIG.I);
- ClassAequipment:
This spot welder complies with the requirements of the technical standard for
products to be used only and exclusively in industrial environments and for
professional purposes.
Correspondence with the electromagnetic compatibility in domestic buildings
and in those directly connected to a low voltage power supply network that
supplies buildings for domestic use is not guaranteed.
INTENDED USE
The system must be used for spot welding one or more steel plates with a low
carbon content, having a shape and size that varies according to the work to
be carried out.
RESIDUAL RISKS
RISK OF CRUSHING THE UPPER LIMBS
DONOTPLACEHANDSNEARMOVINGPARTS!
The spot welder operation mode and the variability of shape and size of the
piece to be worked do not allow the realization of an integrated protection
againstthedangerofcrushingoftheupperlimbs(ngers,hands,forearms).
Theriskmustbereducedusingsuitablepreventivemeasures:
- The operator must be an expert on or trained in resistance welding
procedures using this type of equipment.
- A risk evaluation must be performed for each type of work to be carried out;
it is necessary to use equipment and masks that support and guide the piece
to be worked in order to distance hands from the electrode danger area.
- Whenusingaportablespotwelder:solidlygrasptheclampwithbothhands
placed on the relative handles; always keep hands away from the electrodes.
- Whenevertheshapeofthepieceallowsit,adjusttheelectrodedistanceso
that the stroke does not exceed 6 mm.
- Do not allow two or more people to work simultaneously with the same spot
welder.
- Peopleunconnectedwiththejobmustnotbeallowedintheworkingarea.
- Donotleavethespotwelderunattended:inthiscaseitmustbedisconnected
from the mains; with spot welders with pneumatic cylinder operation move
themainswitchto“O”andlockitwiththesuppliedlock;thekeymustbe
removed and kept by the person in charge.
