Generalinformation
Warning!
This is a class A equipment which may cause radio
interferences in residential areas. In such a case the
operator may be asked to take adequate steps on his
account.
TheGLC 353/503/553MC3 machine withCK 98A is
built according to EN 60 974-1. It corresponds to the
latest "state of the art" engineering and its reliability
isproven.Itmustbeoperatedbytrainedpersonnel in
accordancewiththefollowinginstructionstoprovide
safeandefficientoperation.
The machine is not suitable for thawing
pipelines due to Fire risk !
Flammable gases or gases which induce a chemical
reaction,such asAcetylene, Propane, pureHydro-
gen,pureOxygenareprohibited.

Thiswelding machineisintended forindustrialuse
and must not be used in residential buildings.
As >16 Amp are required per phase, this machine is
subjectto the IEC 61000-3-4 standardor EN61000-3-
12,when it isavailable.In ordertoavoid
electromagnetic interference (EMI), certain conditions
must exist (size of mains impedance) for connection
tothe publiclowvoltage network.Please informthe
relevant electricity supplier about this machine’s
connection. Please do not hesitate to contact your
Electricitysupplier or the manufacturer if you need
helpor information.

Personalprotection(rays,gases,vapours)
—Whenwelding,dryprotectiveclothing,apron,
helmet and gloves as well as solid work shoes
shouldbeworn.
—Use a protective shield or helmet with glass, with
DINmarking,outsideclear,insidetinted.
—Protectother personsin thevicinity of the
weldingarea fromUV raysand spatter by
suitable,non-flammablepartitionwalls.
—Always wear safety glasses if you are in an area
whereweldingtakesplace.
—Wear safety glasses with side protection when
youareweldingorwhenremovingslag.
—Caution!UVraysarereleasedduringwelding.
Protect body and particularly the eyes. Keep
protectiveointmentandeyedropsavailable.
—Allmetalvapoursaretoxic!Becarefulwith
alloys whichcontainlead,cadmium,copper,
zinc,nickle,chrome,berillium.
—Parts, cleaned with chlorinated agents, cause the
toxic gas phosgen to form in the arc.
Caution Risk of poisoning in narrow places !
If shielding gas hoses are not tight or the
shieldinggas valvegetscaught unintentionally,
shielding gas may escape to such an extent that
the oxygen content of the inhaled air decreases;
symptoms of poisoning appear which may lead to
unconsciousnessand suffocation.Sufficient fresh
airmust be provided! Please check the gas
supplyingpartsat regular
intervals.
Fire prevention (explosion)
—Removeallflammablematerialsaroundthe
weldingplaceorcoverthesewithanon-
flammablematerial.
—Hot slag or spatter might cause fires if in contact
withflammablematerials.
—Onlyuse shielding gasessuitablefor welding,
such as Argon, CO2and Argon and CO2or
Argon,CO2andO2mixtures.
NeveruseflammablegaseslikeAcetylene,
Propane,Hydrogenorfiresupportinggasessuch
