Connect the electrode and work cables between the appropriate
output studs of the FX360XL per the following guidelines:
• Most welding applications run with the electrode being
positive (+). For those applications, connect the electrode
cable between the wire drive input power connector and the
positive (+) output stud on the power source. Connect a work
lead from the negative (-) power source output stud to the
work piece.
• When negative electrode polarity is required, such as in some
Innershield applications, reverse the output connections at
the power source (electrode cable to the negative (-) stud,
and work cable to the positive (+) stud).
The following recommendations apply to all output polarities and
weld modes:
•
Select the appropriate size cables per the "Output Cable
Guidelines" below. Excessive voltage drops caused by
undersized welding cables and poor connections often result
in unsatisfactory welding performance. Always use the
largest welding cables (electrode and work) that are practical,
and be sure all connections are clean and tight.
Note: Excessive heat in the weld circuit indicates undersized
cables and/or bad connections.
•
Route all cables directly to the work and wire feeder, avoid
excessive lengths and do not coil excess cable. Route the
electrode and work cables in close proximity to one another
to minimize the loop area and therefore the inductance of the
weld circuit.
• Always weld in a direction away from the work (ground)
connection.
(See Table A.1)
Tabulated below are copper cable sizes recommended for
different currents and duty cycles. Lengths stipulated are the
distance from the welder to work and back to the welder again.
Cable sizes are increased for greater lengths primarily for the
purpose of minimizing voltage drop.
