GENERAL GUN CONNECTION
GUIDELINES

The instructions supplied with the gun and K1500
series gun adapter should be followed when installing
and configuring a gun. What follows are some gener-
al guidelines that are not intended to cover all guns.

a. Check that the drive rolls and guide tubes are

proper for the electrode size and type being used.
If not, change them.

b. Lay the cable out straight. Insert the connector

on the welding conductor cable into the brass
conductor 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.

Note: for Fast-Mate and European connector style

guns, connect gun to gun connector making
sure all pins and gas tube line up with appro-
priate holes in connector. Tighten gun by turn-
ing large nut on gun clockwise.

c. For GMA Gun Cables with separate gas fittings,

connect the 3/16” I.D. gas hose from the wire
drive unit to the gun cable barbed fitting.

d. For water cooled guns see WATER CONNEC-

TIONS in this section.

GMAW SHIELDING GAS

NOTE: Gas supply pressure must be regulated to a
maximum of 80 psi(5.5 bar).

Customer must provide a cylinder of shielding gas, a
pressure regulator, a flow control valve, and a hose
from the flow valve to the gas inlet fitting of the wire
drive unit.

Connect a supply hose from the gas cylinder flow
valve outlet to the 5/8-18 female inert gas fitting on the
back panel of the wire drive or, if used, on the inlet of
the Gas Guard regulator. (See Below).

Gas Guard Regulator - The Gas Guard Regulator is
an optional accessory (K659-1) on these models.

Install the 5/8-18 male outlet of the regulator to the
5/8-18 female gas inlet on the back panel of the wire
drive. Secure fitting with flow adjuster key at top.
Attach gas supply to 5/8-18 female inlet of regulator
per instructions above.

CYLINDER may explode if damaged.
• Keep cylinder upright and chained to

support.

• Keep cylinder away from areas where

it may be damaged.

• Never lift welder with cylinder attached.
• Never allow welding electrode to touch cylinder.
• Keep cylinder away from welding or other live elec-

trical circuits.

BUILDUP OF SHIELDING GAS may
harm health or kill.
Shut off shielding gas supply when not

in use.
