Open the back-end housing on the power
cable of the spool gun by turning each of the
end caps (cap 1 and cap 2) counterclockwise.
This will allow half of the housing to be
removed.
Inside of the housing, you will find
a small DIP switch. If using a
Forney 270 MIG or 242 Dual MIG,
set the switch to the “On” position.
Set the switch to the “Off” position
for use with all other Forney

mechanism.
