- Fasten the two welding cables as close together as possible.
- Keep head and trunk as far away as possible from the welding circuit.
1. GENERAL SAFETY CONSIDERATIONS FOR ARC
- Never wind welding cables around the body.
- Avoid welding with the body within the welding circuit. Keep both cables on the

INSTALLATION AND USE OF EQUIPMENT FOR ARC WELDING).
- Do not leave objects in ferromagnetic material in proximity of the welding
circuit.
- Minimum distance d= 20 cm (Fig. M).
- Avoid direct contact with the welding circuit: the no-load voltage supplied by
the welding machine can be dangerous under certain circumstances.
- When the welding cables are being connected or checks and repairs are
carried out the welding machine should be switched off and disconnected
