SAFETY PRECAUTIONS FOR ELECTRICAL SHOCK
Touching live electrical parts can cause fatal shocks or severe burns . The input power circuit and
the internal circuits of the Orion welder are live when the power switch is turned on . Additionally
the internal capacitors remain charged for a period of time after the Orion is turned off and/or
power is disconnected . Incorrectly installed or improperly grounded equipment is a hazard . This
device was designed to operate indoors only . Do not operate welder in a wet/damp environment .
Holding the hand pieces connected to the front of the welder is okay and will not generate an
electrical shock .
• Remove personal jewelry before welding (i .e . rings, watches, bracelets, etc) .
• Do not touch live electrical parts .
• Wear dry, hole-free insulating gloves and body protection .
• Properly install and ground this equipment according to this manual and national,
state, and local codes .
• Do not weld with wet hands or wet clothing .
• Always verify the supply ground – check and be sure that the input power cord
ground wire is properly connected to a ground terminal in the disconnect box or that
the input power cord plug is connected to a properly grounded receptacle outlet . Do
not remove or bypass the ground prong .
• Keep cords dry, free of oil and grease, and protected from hot metal and sparks .
• Frequently inspect the input power cord and ground conductor for damage or
bare wiring – replace immediately if damaged – bare wiring can kill . Check ground
conductor for continuity .
• Turn off all equipment when not in use .
• Use only well-maintained equipment and repair or replace damaged parts at once .
PERSONAL PROTECTIVE EQUIPMENT RECOMMENDATIONS FOR FLYING SPARKS AND ARC RAYS
It is essential for every person in the immediate work area to wear/utilize proper
Personal Protection Equipment . Arc welding gives off infrared and UV rays that can
burn the retinal tissues within the eyes and cause surface burns to exposed skin,
