5
� Use shortest cables possible for the job
� Use proper sized work clamp and weld cables to accommodate peak amperages
� Separate volt sense lead and feeder control cable from weld cables
� Place weld cables together if possible
� Connect work clamp as close to welding arc as possible
Bad

5
� DO NOT coil cables
� DO NOT share work clamps (no more than 1 machine per clamp)
� DO NOT tangle cables from different machines
� DO NOT splice weld cables

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 cur-
rent rise during droplet transfer into the weld-
ing 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 ca-
ble voltage drop when connected to the weld-
ing 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.
