1. Quick Disconnect Feeder End may be connected
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.
3. Select the proper guide tube I.D. from the table
below.
.023-.052 Electrode Small I.D.
.062-1/8 Electrode Large I.D.
4. Install taper end toward feed rolls. If electrodes
below .045 are being used, it may be advisable to
grind a chisel point on the tapered end to guide
electrode closer to the feed rolls.

that extends beyond quick disconnect
(Refer to
Illustration 1)
:
A. Mark tube at point even with end of quick
disconnect body.
B. Remove guide tube.
C. Cut guide tube at a point 1-1/2” toward the
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.
7. Insert the guide tube in the adaptor. Check guide
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.
