SAFETY PRECAUTIONS WHILE WORKING IN WELDING SHOP-2

 Arc welding

• One should use protective clothing and eye protection devices while performing arc welding operation, otherwise radiation from electric arc will damage the retina of eyes.
• One has to be sure that other people standing nearby also uses eye-protection devices from ultraviolet rays.
• Always use ear protection devices such as muffler because excessive noise caused during the process of arc welding may cause temporary or permanent hearing loss.
• Welder should keep clothing and gloves dry.
• Always keep welding cables free of grease and oil.
• One should prevent the non-insulated portion of the electrode holder from touching the welding ground or job-piece when the current is on.
• Always keep the body insulated from both the work and the metal electrode holder.
• One should carry out the welding process by standing on the insulating material like dry wood rather than on a grounded metal structure.
• It is easier and safer to establish an arc on a clean surface than on a dirty or rusty one.
• Always turn the welding machine off when it is not in use.
• One should not change the polarity switch when the machine is under use. This will burn the surface of the switch and the resulting arc can cause injury to the welder.
• Always avoid using electrode holders with defective jaws or poor insulation.
