2.1 Manual Electrode Holders

Only manual electrode holders which are specifically designed for arc welding and cutting, and are of a capacity capable of safely handling the maximum rated current required by the electrodes, may be used.

Any current-carrying parts passing through the portion of the holder that the operator grips in his hand, and the outer surfaces of the jaws of the holder, must be fully insulated against the maximum voltage encountered to ground.

2.2 Welding Cables and Connectors

Cables in need of repair may not be used. When a cable, other than the cable lead becomes worn to the extent of exposing bare conductors, the portion thus exposed must be protected by means of rubber and friction tape or other equivalent insulation.

2.3 Operating Instructions

Employees must follow these safe means of arc welding and cutting:

When electrode holders are to be left unattended, the electrodes must be removed and the holders placed or protected so that they cannot make electrical contact with employees or conducting objects.

Hot electrode holders may not be dipped in water; to do so may expose the arc welder or cutter to electric shock.

The power supply switch to the equipment must be turned off whenever the welder has to leave his work or stop for any appreciable length of time, or whenever the arc welding or cutting equipment needs to be moved.

Any faulty or defective equipment must be reported to the shop maintenance manager, instructor, or equipment technician.

2.4 Shielding

Whenever practical, all arc welding and cutting operations must be shielded by non combustible or flameproof screens, which will protect employees and other persons working in the vicinity from the direct rays of the arc.
