The toggle switch on the front of the spool
gun adapter box permits quick transfer
between the use of the SP-255 with its
feeder gun and the connected spool gun for
same polarity electrodes.
In either transfer switch position, closing
the gun trigger will cause the electrode
of both guns to be electrically “HOT”. Be
sure unused gun is positioned so that
electrode or tip will not contact metal
case or other metal common to work.
