The method used to arrange cables has
a significant affect on welding
performance. As an example,
Pro-Pulse and RMD welding processes
can produce high welding circuit
inductance depending on cable length
and arrangement. This can result in
limited current rise during droplet
transfer into the welding puddle.
The electrode sense and volt sense
leads are contained in the feeder control
cable and are enabled for all processes.
The volt sense lead automatically
compensates for work cable voltage
drop when connected to the welding
power source.
Do not coil excess cables. Use cables
that are the appropriate length for the
application. Avoid coupling the volt
sense lead with the weld cables.
5-24. Arranging Welding Cables To Reduce Welding Circuit Inductance
Bad
S DO NOT coil cables
S DO NOT share work clamps (no more than 1 machine per clamp)
S DO NOT tangle cables from different machines
S DO NOT splice weld cables
Ideal
S Use shortest cables possible for the job
S Use proper sized work clamp and weld cables to accommodate peak amperages
S Separate volt sense lead and feeder control cable from weld cables
S Place weld cables together if possible
S Connect work clamp as close to welding arc as possible
