SHIELDING
The selective shielding of other cables and equipment present
in the surrounding area may reduce the problems due to inter-
ference. The shielding of the entire welding installation can be
taken in consideration for special applications.

- Connect the signal cable (1) to the appropriate connector.
- Connect the power cable (2) to the appropriate fastening.
- Tighten the cable clamps and close the left-hand side cover.
- Connect the gas pipe to the rear hose fitting.
2.5 Commissioning
- Check that the roller groove coincides with the diameter of
the wire you wish to use.
- Unscrew the ring nut (1) from the coil reel and insert the
coil.
Fit the reel metal pin into its housing, replace the ring nut
(1) and adjust the friction screw (2).
- Release the feed support of the gearmotor (3), sliding the
end of the wire into the wire guide bush and, passing it over
the roller, into the torch fitting.
Lock the feed support (3) in position, checking that the wire
has entered the roller groove.
- Insert the torch, complete with sheath, into the central fit-
ting (4), fully tightening the ring nut.
