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.
