Thanks for all the advise. I found the problem.
I disconnected the wire (W/B) at a junction box
the problem cleared. I not why this worked because
this wire was disconnected at the set and the
BIX block having no access to the system.
Thanks

Subject: Welding Arc Sound over Lines

Hi Gang,
I have a situation with an Electronic Welding Machine when used provides
the Arc sound over the Lines on all sets. This welder is used for
aluminum welding. It only happens when the operator begins welding. When
the machine is on and the operator is not welding nothing on the lines.
All 3 lines and grounding has been verified by the local telephone
company as OK. Also, according to the customer an electrician has been
in and verified all the grounding on premises is OK, including the
welding machine.
We thought we isolated the trouble to a Cat3 wire cable tied to an
electrical conduit that passed by and over the machine to a set
approximately 30 ft away, using W/B. This cable also has a 24V paging
speaker using the W/O & W/G.
I ran a Cat5E from the equipment to the phone, by passing the machine
and keeping the speaker on the Cat3. I also doubled up on the pairs to
the set using the W/B B/W for Tip and the W/O O/W for the Ring.
All thought to rectify this problem is appreciated.
Thanks
Bob
