Use the shortest possible lengths of hose to avoid damage, reduce pressure drop, and prevent
possible volume flow restriction. Let the hose lie as straight as possible to prevent kinks when
interconnecting system components. Coil excess hose and place it out of the way to prevent
damage and reduce tripping danger.
Check hose regularly for wear, leaks, loose connections, or damage from heat, flames or sparks.
Immediately replace damaged or unreliable hose!
Pressure Regulators - Maintain all pressure regulators used on the Plasma Unit of the Vulcan in
proper working order to avoid failure and danger to operating personnel. Do not use any regulator
that leaks, creeps excessively, or is otherwise damaged. It is strongly recommended that any
malfunctioningequipmentbeservicedonlybytrainedtechnicians,atit’smanufacturer’sdesignated

NOISE PREVENTION -Theplasmacuttingprocesscangeneratehighlevelsofnoise. Depending
upon the arc current, material being cut, acoustics, and size of the cutting room, distance from the
torch, and other factors, acceptable noise levels as defined by national, state, or local codes may
be exceeded by your plasma system.
GROUNDING - Before operating the plasma system:
InputPower-Besurethepowercordispluggedintoaproperlygroundedoutletorthatthepowercord
ground wire is properly connected to the ground in the disconnect box. If installation of the plasma
system involves connecting a power cord to the power supply, ensure that the power cord ground
wireisproperlyconnected. Conformtonational,state,andlocalstandardwhenfasteningthepower
ground wire to the power supply chassis. CSA standards recommends placing the power cord

Make sure that all electrical connections are tight to avoid excessive heating.
Input Power - Connect ground lead of power input cable to both electrical system ground in
disconnectbox,andtogroundstudinPlasmaUnitpowersupply. Becertainallgroundlugsarelarge
enough to carry rated current load and make all connections tight to prevent resistance heating.
Output Power - Connect all positive output ground leads to cutting table Star Ground (referred to,
and illustrated in Section 1). Connect Star Ground to reliable Earth Ground. Refer to National
Electrical Code, Grounding Electrode System or other appropriate source for suitable Ground
specifications.
WorkTable - Clamptheworkcable withgoodmetal-to-metalcontact totheworkpiece(not thedrop
off portion) or to the work table itself.
Connecttheworktabletoagoodearthground. ConsulttheU.S.NationalElectricalCode,Article250,
Section H Grounding Electrode System, or other appropriate national, state, or local codes.
