There are possible hazardswith this procedure! The possible hazards are shown inthe adjoining a special safety Note ; not safety group of symbols means Warning! Watch Out! possibleELECTRIC SHOCK, MOVING PARTS, and HOT PARTS symbols and related instructions below for necessary actionsto avoid the Arc Welding HazardsYThe symbols shown below are used throughout this manual tocall attention to and identify possible hazards. When you seethe symbol, watch out, and follow the related instructions toavoid the hazard.

7 The safety information given below is onlya summary of the more complete safety information found inthe Safety Standards listed in Section 1-5. Read and follow allSafety qualified persons should install, operate, maintain, andrepair this operation, keep everybody, especially children, SHOCK can 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 automatic wire welding, thewire, wire reel, drive roll housing, and all metal parts touching thewelding wire are electrically live. Incorrectly installed or improperlygrounded equipment is a not touch live electrical dry, hole-free insulating gloves and body yourself from work and ground using dry insulating matsor covers big enough to prevent any physical contact with the workor not use AC output in damp areas, if movement is confined, or ifthere is a danger of AC output ONLY if required for the welding AC output is required, use remote output control if present 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.

8 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. 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!DDisconnect input power or stop engine before installing orservicing this equipment. Lockout/tagout input power according toOSHA 29 CFR (see Safety Standards).DProperly install and ground this equipment according to itsOwner s manual and national, state, and local 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 making input connections, attach proper grounding conduc-tor first double-check inspect input power cord for damage or bare wiring replace cord immediately if damaged bare wiring can off all equipment when not in not use worn, damaged, undersized, or poorly spliced not drape cables over your earth grounding of the workpiece is required.

9 Ground it directlywith a separate not touch electrode if you are in contact with the work, ground,or another electrode from a different not touch electrode holders connected to two welding ma-chines at the same time since double open-circuit voltage will only well-maintained equipment. Repair or replace damagedparts at once. Maintain unit according to a safety harness if working above floor all panels and covers securely in work cable with good metal-to-metal contact to workpieceor worktable as near the weld as work clamp when not connected to workpiece to preventcontact with any metal not connect more than one electrode or work cable to anysingle weld output DC VOLTAGE exists in inverter-typewelding power sources after removal of Off inverter, disconnect input power, and discharge inputcapacitors according to instructions in Maintenance Sectionbefore touching any produces fumes and gases.

10 Breathingthese fumes and gases can be hazardous to AND GASES can be your head out of the fumes. Do not breathe the inside, ventilate the area and/or use local forced ventilation at thearc to remove welding fumes and ventilation is poor, wear an approved air-supplied and understand the Material Safety Data Sheets (MSDSs)and the manufacturer s instructions for metals, consumables,coatings, cleaners, and in a confined space only if it is well ventilated, or whilewearing an air-supplied respirator. Always have a trained watch-person nearby. Welding fumes and gases can displace air andlower the oxygen level causing injury or death. Be sure the breath-ing air is not weld in locations near degreasing, cleaning, or spraying op-erations.
