Thepossible hazards are shown in the adjoining symbolsor explained in the a hazardous situation which, if not avoided,could result in death or serious injury. The possiblehazards are shown in the adjoining symbols or ex-plained in the Indicates statements not related to personal injury. Indicates special group of symbols means Warning! Watch Out! ELECTRICSHOCK, MOVING PARTS, and HOT PARTS hazards. Consult sym-bols and related instructions below for necessary actions to avoid Arc Welding HazardsThe symbols shown below are used throughout this manualto call attention to and identify possible hazards.

7 When yousee the symbol, watch out, and follow the related instructionsto avoid the hazard. The safety information given below isonly a summary of the more complete safety informationfound in the Safety Standards listed in Section 1-7. Read andfollow all Safety qualified persons should install, operate, maintain, andrepair this operation, keep everybody, especially children, live electrical parts can cause fatal shocksor severe burns. The electrode and work circuit iselectrically live whenever the output is on. The inputpower circuit and machine internal circuits are alsolive when power is on. In semiautomatic or automat-ic wire welding, the wire, wire reel, drive roll housing,and all metal parts touching the welding wire areelectrically live.

8 Incorrectly installed or improperlygrounded equipment is a SHOCK can kill. Do not touch live electrical parts. Wear dry, hole-free insulating gloves and body protection. Insulate yourself from work and ground using dry insulating matsor covers big enough to prevent any physical contact with the workor ground. Do not use AC output in damp areas, if movement is confined, or ifthere is a danger of falling. Use AC output ONLY if required for the welding process. If AC output is required, use remote output control if present onunit. Additional safety precautions are required when any of the follow-ing electrically hazardous conditions are present: in damplocations or while wearing wet clothing; on metal structures suchas floors, gratings, or scaffolds; when in cramped positions suchas sitting, kneeling, or lying; or when there is a high risk of unavoid-able or accidental contact with the workpiece or ground.

9 For theseconditions, use the following equipment in order presented: 1) asemiautomatic DC constant voltage (wire) welder, 2) a DC manual(stick) welder, or 3) an AC welder with reduced open-circuit volt-age. In most situations, use of a DC, constant voltage wire welderis recommended. And, do not work alone! Disconnect input power or stop engine before installing orservicing this equipment. Lockout/tagout input power according toOSHA 29 CFR (see Safety Standards). Properly install, ground, and operate this equipment according toits Owner s Manual and national, state, and local codes. Always verify the supply ground check and be sure that inputpower cord ground wire is properly connected to ground terminal indisconnect box or that cord plug is connected to a properlygrounded receptacle outlet.

10 When making input connections, attach proper grounding conduc-tor first double-check connections. Keep cords dry, free of oil and grease, and protected from hot metaland sparks. Frequently inspect input power cord and ground conductor fordamage or bare wiring replace immediately if damaged barewiring can kill. Turn off all equipment when not in use. Do not use worn, damaged, undersized, or repaired cables. Do not drape cables over your body. If earth grounding of the workpiece is required, ground it directlywith a separate cable. Do not touch electrode if you are in contact with the work, ground,or another electrode from a different machine. Use only well-maintained equipment. Repair or replace damagedparts at once.
