MAKING A WELD WITH THE SPOOL
GUN ADAPTER (K607-1) INSTALLED
The toggle switch on the front of the spool gun adapter
box permits quick transfer when you want to switch
between using the WIRE-MATIC 250 Feeder Gun and
the connected Spool Gun when the electrodes are at
the same polarity.
In either transfer switch position, closing the gun
trigger will cause the electrode of both guns to be
electrically energized, or "HOT." Be sure the
unused gun is positioned so the electrode or the
tip will not contact metal case or other metal com-
mon to the work.
____________________________________
When the transfer switch is in the Feeder Gun position:
a. The Spool Gun trigger, wire feed, and gas out-
put are disabled.
b. Closing the Feeder Gun trigger Starts Feeder
Gun welding and makes the Feeder Gun and
the Spool Gun electrodes electrically "HOT."
When the transfer switch is in the Spool Gun position:
a. The Feeder Gun, wire feed, and gas output
are disabled.
b. Closing the Spool Gun trigger makes both the
Feeder Gun and Spool Gun electrodes electri-
cally "HOT" and activates Spool Gun gas out-
put.
MAKING THE WELD:
1. Set the transfer switch in the SPOOL GUN posi-
tion.
2. Turn input power ON by setting the POWER
SWITCH in the ON position.
3. Adjust the VOLTAGE CONTROL KNOB to
increase or decrease your welding Voltage.
4. Adjusting the Wire Speed Control will increase or
decrease the Spool Gun Wire Feed Speed. This
represents the set speed for the K469 Spool Gun
and the maximum set speed for the K487 Spool
Gun with the remote control in gun handle at max-
imum.
The remote control turned to minimum will give
approximately 50% of the maximum set WFS.
NOTE: The WIRE-MATIC 250 speed calibrated dial
markings are not accurate when used for setting the
Spool Gun speed.
The following procedure settings can be used as initial
settings for making test welds to determine final set-
tings:
5. To return to normal WIRE-MATIC 250 welding, set
the transfer switch to FEEDER GUN position and
reset feeder gun weld procedure settings.
