The safety guards and moving parts of the covering of the welding machine and
of the wire feeder should be in their proper positions before connecting the
welding machine to the power supply.
- The flow of the welding current generates electromagnetic fields (EMF) around
the welding circuit.
Electromagnetic fields can interfere with certain medical equipment (e.g. Pace-
makers, respiratory equipment, metallic prostheses etc.).
