directly to a Bernard adaptor by threading quick
disconnect directly into adaptor. Make all necessary
power, control, and gas connections.
2. Quick Disconnect Feeder End, PN 4920 is supplied
with two long guide tubes

(PN 478 and 479)

of
different I.D.’s which must be cut to the proper
length.

that extends beyond quick disconnect
(Refer to

disconnect body.
B. Remove guide tube.

taper from the area marked.
D. Reinstall in adaptor and tighten set screw.
6. Procedure to determine cut length for guide tube
recessed within quick disconnect
(Refer to

Illustration 2).

A. With small rule, measure amount guide tube
is within quick disconnect body.
B. Using formula below, cut guide tube to proper
length. Shorten guide tube from end opposite
taper.
C. 1-1/2” minus distance measured inside the
quick disconnect body equals length to be
shortened.

tube length as indicated in Illustration 3 for proper fit
and tighten set screw. E-Z Feed Adaptor Kits are
supplied with pre-cut guide tubes for specific
machines, as indicated below.
