Safety regulations
General safety rules when working with welding:

1) Constantly monitor the formation of the weld seam.


2) Protect the work area with a 1.8 meter high shield to prevent the
welding arc from harming bystanders.
3) Make sure that the workplace is free of debris and flammable objects.
4) Use eye and face protection

5) When working at height, use safety harnesses.

6) Move welding only after the power supply has


completely stopped.
7) Make sure that the welding cables do not become twisted during operation.

8) When performing body work on vehicles, be sure to disconnect the battery.

9) Be sure to wear special clothing: leggings made of fire-resistant materials,


shoes made of leather and felt, a protective mask and, if necessary, respirators
and a hard hat.
