Never use an oxygen hose for any gas other than oxygen.
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 to eliminate tripping danger.
Checkhoseregularlyforwear,leaks,looseconnections,oranydamagefromheat,flameorsparks.
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

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.

ELECTRIC AND MAGNETIC FIELDS (EMF)
Plasma arc cutting and gouging systems create electric and magnetic fields that may interfere with
the correct operation of electronic health support equipment, such as pacemakers or hearing aids.
