GUN CONNECTIONS - GENERAL
4-roll feed plates are equipped with a brass connector
bar at the gun-end of the feed plate to allow a bolted
brass-to-brass electrical connection to be made direct-
ly to either standard or Fast-mate gun adapter bush-
ings. Use a 1/4” inch allen key on the factory-installed
socket head cap screw to insure that the connector
bar is securely tightened to the adapter bushing.
GUN AND CABLE ASSEMBLIES
WITH STANDARD CONNECTION
The 10 Series Wire Drive Head requires a K1500 Gun
Adapter installed See “Gun Adapters” in ACCES-
SORIES section. The K1500-2 Gun Adapter and
Trigger Cable for Magnum 200-400 guns are factory
included with the STT-10.
GMAW Guns
An expanding line of Magnum gun and cable assem-
blies are available to allow welding with solid and
cored electrodes using the GMAW process. See the
appropriate Magnum literature for descriptions of the
200 to 550 ampere air cooled gun and cables that are
available. Gun cable lengths range from 10 ft. (3.0 m)
to 25 ft. (7.6 m) and feed electrode sizes .025" (0.6
mm) to 3/32" (2.4 mm). The entire line of Magnum
Fast-Mate gun and cable assemblies can also be
used by installing a K489-2 Fast-Mate adapter kit.
See “Gun and Cable Assemblies with Fast-Mate
Connection” in this section for details.
Gun Cable Connection with Standard
Connection
1. Check that the drive rolls and guide tubes are
proper for the electrode size and type being used.
If necessary, change them per “Wire Drive Roll
Kits” in this section.
2. Lay the cable out straight. Insert the connector on
the welding conductor cable into the brass conduc-
tor block on the front of the wire drive head. Make
sure it is all the way in and tighten the hand clamp.
Keep this connection clean and bright. Connect
the trigger control cable polarized plug into the
mating 5 cavity receptacle on the front of the wire
drive unit.
3. For GMA Gun Cables with separate gas fitting (10
Series Wire Drive using K1500-1 Gun Adapter),
connect the 3/16" I.D. gas hose from the wire drive
unit to the gun cable barbed fitting.

GMAW Guns
An expanding line of Magnum Fast-Mate™ air cooled
and water cooled gun and cable assemblies are avail-
able to allow welding with solid and cored electrodes
using the GMAW process. See the appropriate
Magnum literature for descriptions of the 200 to 400
ampere air cooled gun and cables that are available
as well as the Magnum “Super Cool” 450 ampere
water cooled gun and cable. Gun cable lengths range
from 10 ft. (3.0 m) to 25 ft. (7.6 m) and feed electrode
sizes .025" (0.6 mm) to 5/64" (20 mm).
An expanding line of Magnum X-Tractor gun and
cable assemblies provides fume extraction capability

GMAW process. See the appropriate Magnum litera-
ture for descriptions of the 250 to 400 ampere air
cooled gun and cables that are available. Gun cable
lengths range from 10 ft. (3.0 m) to 15 ft. (4.5 m) and
feed electrode sizes .035" (0.9 mm) to 1/16" (1.6 mm).
These guns require the use of either the K173-1 or
K184* vacuum units.
* Requires S14927-8 connector hose and an S20591
hose adapter.
