oUtpUt polarity connections

The welding machine features a short lead protruding from the
front of the machine, the lead can be used to configure the wire
drive polarity. For STICK welding the short lead does not need to
be connected and this lead will not be electrically hot. For FCAW,
MIG, and TIG welding this lead can be connected to either the
positive output stud or negative output stud. Connecting the lead
to the positive stud will electrically connect the wire drive to
positive polarity; the work clamp would then connect to the
negative stud. Ensure connector is tightly locked into place by
rotating clockwise.
