4) Special nozzle
Long nozzle
Good for welding of
deep section.
Note
: For "nozzle for gas lens", it is necessary to prepare collet body and nozzle packing for gas lens.
5) Ground ring assembly (CWX00560)
If the arc spark is insufficient, you can install this ground
ring to improve it. (For details, see the instruction manual
supplied with the ground ring assembly.)
Note
In case of installing for the first time, please consult Pana-
sonic representatives.
(An installation error may cause damage to the torch, or
may not improve the arc start.)

Nozzle for gas lens (GL)
Good for welding of those that
require high shielding perfor-
mance, such as titanium and spe-
cial alloy.
Even though this
distance becomes
longer, a uniform
shield effect can be
obtained.
