D
D
Wear a safety harness if working above floor level.  
Keep all panels and covers securely in place.  
Clamp work cable with good metal-to-metal contact to workpiece  
or worktable as near the weld as practical.  
Insulate work clamp when not connected to workpiece to prevent  
contact with any metal object.  
Do not connect more than one electrode or work cable to any  
single weld output terminal.  
Touching live electrical parts can cause fatal shocks  
or severe burns. The electrode and work circuit is  
electrically live whenever the output is on. The input  
power circuit and machine internal circuits are also  
live when power is on. In semiautomatic or automatic wire welding, the  
wire, wire reel, drive roll housing, and all metal parts touching the  
welding wire are electrically live. Incorrectly installed or improperly  
groundedequipment is a hazard.

welding power sources after removal of input  
power.  
D
Turn Off inverter, disconnect input power, and discharge input  
capacitors according to instructions in Maintenance Section  
before touching any parts.  
D
D
D
FUMES AND GASES can be hazardous.  
D
Additionalsafety precautions are required when any of the follow-  
ing electrically hazardous conditions are present: in damp  
locations or while wearing wet clothing; on metal structures such  
as floors, gratings, or scaffolds; when in cramped positions such  
as sitting, kneeling, or lying; or when there is a high risk of unavoid-  
able or accidental contact with the workpiece or ground. For these  
conditions, use the following equipment in order presented: 1) a  
semiautomaticDC 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 welder  
is recommended. And, do not work alone!  
Welding produces fumes and gases. Breathing  
these fumes and gases can be hazardous to your  
health.  
D
D
Keep your head out of the fumes. Do not breathe the fumes.  
If inside, ventilate the area and/or use local forced ventilation at the  
arc to remove welding fumes and gases.  
D
D
If ventilation is poor, wear an approved air-supplied respirator.  
Read and understand the Material Safety Data Sheets (MSDSs)  
and the manufacturer’s instructions for metals, consumables,  
coatings, cleaners, and degreasers.  
Work in a confined space only if it is well ventilated, or while  
wearing an air-supplied respirator. Always have a trained watch-  
person nearby. Welding fumes and gases can displace air and  
lower the oxygen level causing injury or death. Be sure the breath-  
ing air is safe.  
Do not weld in locations near degreasing, cleaning, or spraying op-  
erations. The heat and rays of the arc can react with vapors to form  
highly toxic and irritating gases.  
Do not weld on coated metals, such as galvanized, lead, or  
cadmiumplated steel, unless the coating is removed from the weld  
area, the area is well ventilated, and while wearing an air-supplied  
respirator. The coatings and any metals containing these elements  
can give off toxic fumes if welded.

1-5. EMF Information  
Considerations About Welding And The Effects Of Low Frequency  
Electric And Magnetic Fields  
1. Keep cables close together by twisting or taping them.  
2. Arrange cables to one side and away from the operator.  
3. Do not coil or drape cables around your body.  
Welding current, as it flows through welding cables, will cause electro-  
magnetic fields. There has been and still is some concern about such  
fields. However, after examining more than 500 studies spanning 17  
years of research, a special blue ribbon committee of the National  
Research Council concluded that: “The body of evidence, in the  
committees judgment, has not demonstrated that exposure to power-  
frequency electric and magnetic fields is a human-health hazard.”  
However, studies are still going forth and evidence continues to be  
examined.Until the final conclusions of the research are reached, you  
may wish to minimize your exposure to electromagnetic fields when  
welding or cutting.  
4. Keep welding power source and cables as far away from opera-  
tor as practical.  
5. Connect work clamp to workpiece as close to the weld as possi-  
ble.  
About Pacemakers:  
Pacemaker wearers consult your doctor before welding or going near  
welding operations. If cleared by your doctor, then following the above  
procedures is recommended.  
To reduce magnetic fields in the workplace, use the following  
procedures:
