in case you forget, refer to the illustrations below.

The MIG gun must also be correct in polarity. Drop open the cover on the
left side of the MIG to access the wire spool and feeder. Just above the
feeder, the are two terminal lugs. The upper is Positive, and the lower is
negative. If there are no positive (+) or negative (-) symbols, there may also
be a label that says "Gas MIG" and "Gasless" or something similar. Regard-
less, the top terminal is positive and the bottom terminal is negative. For
MIG, the wire feeder cable should be connected to the top, positive (+) ter-
minal with via the provided screw. See below.

Even though similar in concept, MIG/MAG (GMAW) and Gas-less
Flux-Cored (FCAW) welding require a polarity change when transi-
tioning between the two. The unit will remind you with an on-screen
prompt to change polarity when you change between the processes,
but this is an often over-looked issue, even when reminded by the

machine. Failure to change polarity will result in erratic operation, bird's
nesting of the wire, poor fusion and excess spatter. Use illustrations
below as a guide.

When welding most all flux-cored wires, polarity will be negative. There are a
small number of exceptions. However, if the manufacturer doesn't state the
polarity, assume it is negative. Drop open the cover on the left side of the
MIG to access the wire spool and feeder. Just above the feeder, the are two
terminal lugs. The upper is Positive, and the lower is negative. If there are
no positive (+) or negative (-) symbols, there may also be a label that says
"Gas MIG" and "Gasless" or something similar. Connect the wire feeder
cable to the bottom terminal lug via the provided screw.
This unit is not designed for or intended to be used in dual shield
operation (FCAW-G). The Flux-cored operation that this machine
supports is a gasless process (FCAW). The PowerSet and manual
function is programmed for this type of operation.
