iv)Alwayswearthecorrectprotectiveclothingforprotectionfromsparks,molten

particlesandarcrays.

v)Whenweldinginconfinedspaces,alwaysensureadequateventilationandconstant

observationoftheoperator.

vi)Keepcombustiblematerialsawayfromtheweldingarea.Havea suitablefire

3.1Environment

TheTransmig180isNOTdesignedforuseinenvironmentswithincreasedhazardofelectricshock

asdennedinAS3195-1990.

a)Examplesofenvironmentswithincreasedhazardofelectricshockare-

i)Inlocationsinwhichfreedomofmovementisrestricted,sothattheoperatoris

forcedtoperformtheworkina cramped(kneeling,sittingorlying)positionwith

physicalcontactwithconductiveparts;

ii)Inlocationswhicharefullyorpartiallylimitedbyconductiveelements,andinwhich

thereisa highriskofunavoidableoraccidentalcontactbytheoperator,or

iii)Inwetordamphotlocationswherehumidityorperspirationconsiderablereducesthe

skinresistanceofthehumanbodyandtheinsulationpropertiesofaccessories.

b)Environmentswithincreasedhazardofelectricshockdonotincludeplaceswhere

electricallyconductivepartsinthenearvicinityoftheoperator,whichcancauseincreased

hazard,havebeeninsulated.

3.2Location

BesuretolocatethePowerSourceaccordingtothefollowingguidelines:

a)Inareas,freefrommoistureanddust.

b)Ambienttemperature0°Cto40°C.

c)Inareas,freefromoil,steamandcorrosivegases.

d)Inareas,notsubjectedtoabnormalvibrationorshock.

e)Inareas,notexposedtodirectsunlightorrain.

f)Placeata distanceof30cmormorefromwallsorsimilarthatcouldrestrictnaturalairflow

g)Theminimumgroundclearanceforthisproductis65mm.

3.3Ventilation

Sincetheinhalationofweldingfumescanbeharmful,ensurethattheweldingareaiseffectively

ventilated.

3.4MainsSupplyVoltageRequirements

TheMainssupplyvoltageshouldbewithin± 10%oftheratedMainssupplyvoltage.Toolowa

voltagemaycausepoorweldingperformanceorthewirefeedertomalfunction.Toohigha supply

voltagewillcausecomponentstooverheatandpossiblyfail.

TheTransmig180issuppliedwitha 15Ainputlead(and15Aplug)toconnecttoa 15Apower

outletandisfactorysetfor240Voperation

CAUTION 1: CIGWELD advises that you should avoid the use of extension leads as this can

reduce the Mains supply voltage below 10% of the rated Mains supply voltage.

3.5AlternativeMainsSupplyVoltageConnection

TheTransmig180canberewiredtooperateona Mainssupplyvoltageof220V.

WARNING 1: CIGWELD advises that a qualified electrical tradesperson rewire your Transmig

180 for 220V operation.

a)DisconnecttheTransmig180fromtheMainssupplyvoltage.

b)DisconnectwireNo7 fromterminalL3thenreconnectittoterminalL2onthecontactor.

RefertoFigure2.
