• Wire feeder side connecting cable: connect the red and
blue pipes to their respective bulkhead grommets on the
rear panel of the feeder.
2) Connect up the earthing system cable to the rapid coupling
marked by a - (negative) symbol and then the relevant ground
clamps to the piece being welded or to its support in an area
free from rust, paint and grease. Using particularly long earth-
ing cables reduces the voltage and causes some problems
from increased resistance and inductance of the cables that
could cause faulty welding. Follow instructions to avoid these
problems:
• Use earthing and extension cables with appropriate section.
• Lay out the cables as a flat as possible to prevent them
from coiling up.
2B - Connecting the cables - Welding with a NEGATIVE
POLE TORCH (Fig. B2)
1) Connect the generator - feeder connection cable using the ex-
tension cable in addition to invert the polarity (optional).
WARNING: Do not disconnect the wire-feeder until the ma-
chine has been switched off.
