MAKING A WELD WITH THE SPOOL
GUN ADAPTER (K672-1) INSTALLED
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 posi-
tioned so the electrode or the tip will not contact
metal case or other metal common to the work. A
gun holder is provided with the K672-1 kit for this
purpose.
____________________________________
1. The transfer switch in FEEDER position:
a. Disables spool gun trigger, wire feed, and gas
output.
b. Closing the feeder gun trigger starts feeder
gun welding and makes both electrodes elec-
trically "HOT."
2. Transfer switch in SPOOL position:
a. Disables feeder gun wire feed and gas output.
However, closing feeder gun trigger will make
both electrodes electrically “HOT” and activate
spool gun gas output.
b. Closing spool gun trigger starts spool gun
welding and makes both electrodes electrical-
ly "HOT".
3. Operation with Wire-Matic 255:
a. Turn the Wire-Matic input power ON, and the
transfer switch is to be in the SPOOL position.
b. Adjusting the voltage control will increase or
decrease your welding Voltage.
c. 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 maximum.
The remote control turned to minimum will give
approximately 50% of the maximum set WFS.
NOTE: The WIRE-MATIC 255 speed calibrated dial
markings are not accurate when used for setting the
Spool Gun speed.
4. The following procedure settings can be used as
initial settings for making test welds to determine
final settings:
5. To return to normal WIRE-MATIC 255 welding, set
the transfer switch to FEEDER position and reset
feeder gun weld procedure settings.
