In semiautomatic or automatic wire welding, the electrode, electrode reel, welding head, 
nozzle or semiautomatic welding gun are also electrically “hot”. 

 

Always be sure the work cable makes a good electrical connection with the metal being 
welded. The connection should be as close as possible to the area being welded. 

 

Maintain the electrode holder, work clamp, welding cable and welding machine in good, 
safe operating condition. Replace damaged insulation. 

 

Never dip the electrode in water for cooling. 

 

Never simultaneously touch electrically “hot” parts of electrode holders connected to two 
welders because voltage between the two can be the total of the open circuit voltage of 
both welders. 

 

When working above the floor level, use a safety belt to protect yourself from a fall 
should you get a shock.

 

 

 

FUMES AND GASES CAN BE DANGEROUS. 

 

Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes 
and gases. When welding, keep your head out of the fume. Use enough ventilation and/or 
exhaust at the arc to keep fumes and gases away from the breathing zone. When welding 
with electrodes which require special ventilation such as stainless or hard facing or on 
lead or cadmium plated steel and other metals or coatings which produce highly toxic 
fumes, keep exposure as low as possible and below Threshold Limit Values using local 
exhaust or mechanical ventilation. In confined spaces or in some circumstances, outdoors, 
a respirator may be required. Additional precautions are also required when welding on 
galvanized steel.  

 

Do not weld in locations near chlorinated hydrocarbon vapors coming from degreasing, 
cleaning or spraying operations. The heat and rays of the arc can react with solvent 
vapors to form phosgene, a highly toxic gas, and other irritating products. 

 

Shielded gases used for arc welding can displace air and cause injury or death. Always use 
enough ventilation, especially in confined areas, to insure breathing air is safe. 

 

Read and understand the manufacturer’s instructions for this equipment and the 
consumables to be used, including the material safety data sheet and follow your 
employer’s safety practices. 

 

 

ARC RAYS CAN BURN. 

 

Use a shield with the proper filter and cover plates to protect your eyes from sparks and 
the rays of the arc when welding or observing open arc welding.  

 

Use suitable clothing made from durable flame-resistant material to protect your skin and 
that of your helpers from the arc rays.
