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 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. 

  Shielding 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. 

 Protect other nearby personnel with suitable, non-flammable screening and /or warn them not to 

watch the arc nor expose themselves to the arc rays or to hot spatter or metal. 

 

SELF-PROTECTION   

 Keep all equipment safety guards, covers and devices in position and in good repair. Keep hands, 

hair, clothing and tools away from V-belts, gears, fans and all other moving parts when starting,
