SAFETY

2

  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 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.
