Safety Regulations

You, as the welder, must have a thorough knowledge of the safety precautions relating to the job. That is not all; you should also consider it your responsibility to observe all of the applicable safety precautions. When welding, carelessness can cause serious injury to your-self as well as others.

Bear in mind the safety precautions for operating welding equipment can vary considerably because of the different types of equipment involved; therefore, only general precautions on operating metal arc-welding equipment are presented here. For specific instructions on the operation and maintenance of your individual equipment, consult the equipment manufacturer’s instruction manual. In regards to general precautions, know your equipment and how to operate it. Use only approved welding equipment, and ensure that it is maintained properly.

Before you start welding, ensure that the welding machine frame is grounded, that neither terminal of the welding generator is bonded to the frame, and that all electrical connections are secure. The ground connection must be attached firmly to the work, not merely laid loosely upon it.

  • Keep welding cables dry and free of oil or grease.
  • Keep the cables in good condition and always take appropriate steps to protect them from damage. When it is necessary to run cables some distance from the ma-chine, lay them overhead, if at all possible, using adequate support devices.
  • When you are using portable machines, make sure that the primary power cable is separate from the welding cables so they do not become entangled. Any portable equipment mounted on wheels should be securely blocked to prevent accidental movement during welding operations.
  • When stopping work for any appreciable length of time, be sure to de-energize the equipment. When the equipment is not in use, you should completely disconnect it from its source of power.
  • Keep the work area neat and clean. If at all possible, make it a practice to dispose the hot electrode stubs in a metal container.
