POTENTIAL HAZARDS When any of the welding processes are used, the molten puddle should be shielded from the air in order to obtain a high quality weld deposit. In shielded metal arc welding, shielding from the air is accomplished by gases produced by the disintegration of the coating in the arc. With gas shielded arc welding, shielding from the air

In addition to using portable screens to protect other personnel, screens should be used, when necessary, to prevent drafts of air from interfering with the stability of the arc. c. Arc welding operations give off an intense

Ordinary household voltage (115 V) is higher than the output voltage of a conventional arc welding machine. b. Although the ac and dc open circuit voltages are low compared to voltages used for lighting circuits and motor
Read more →a. Do not allow hoses to come in contact with oil or grease. These will penetrate and deteriorate the rubber and constitute a hazard with oxygen. b. Always protect hoses from being walked on or run over. Avoid kinks and tangles. Do not leave hoses where anyone can trip over them. This could result in personal injury, damaged connections, or
