GMAW Shielding Gas
WARNING
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.
SEE AMERICAN NATIONAL STANDARD Z-49.1,
"SAFETY IN WELDING AND CUTTING" PUBLISHED
BY THE AMERICAN WELDING SOCIETY.
------------------------------------------------------------------------
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.
ELECTRICAL INSTALLATION
WARNING
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts such
as output terminals or internal wiring.
• When inching with gun trigger, electrode and
drive mechanism are "hot" to work and
ground and could remain energized several
seconds after the gun trigger is released.
• Turn OFF input power at welding power
source before installation or changing
drive roll and/or guide tubes.
• Welding power source must be connected
to system ground per the National
Electrical Code or any applicable local
codes.
• Only qualified personnel should
perform this installation.
Observe all additional Safety Guidelines detailed throughout this manual.

INSTALLATION
Input Cable: LN-10 Control to Power
Source
K1501-10 (Control Cable only)
Consists of a 9-conductor control cable with 14-pin
control cable plug, without electrode cable, and is
available in a length of 10 ft. (3 m).
With input power disconnected from the power
source, install the input cable per the following:
1) Connect the end of the control cable with the 14-
pin cable plug to the mating receptacle on the
power source.
2) Connect the electrode lead to the power source
output terminal of the desired polarity.
3) Connect the 9-socket plug of the control cable to
the mating receptacle on the bottom of the LN-10
control box.
4) Slip the current sensor cover off enough to expose
the input connector stud. Connect the electrode
cable from the power source to this stud with the
nut provided, then reclose the current sensor
cover.
Work Cable
Connect a work lead of sufficient size and length (per
the following table) between the proper output termi-
nal on the power source and the work. Be sure the
connection to the work makes tight metal-to-metal
electrical contact.
