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.
------------------------------------------------------------------------
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.
INSTALLATION

ELECTRICAL INSTALLATION

Observe all additional Safety Guidelines detailed throughout this manual.
INPUT CABLE: DH-10 CONTROL TO
POWER SOURCE
Available Cable Assemblies:
K1501-10 (Control Cable Only) Consists of a 9-con-
ductor control cable with a 14-pin control cable plug,
without electrode cable, and is available in lengths of
10 ft. (3 m).
K1797-25 Consists of a 14-conductor control cable
extension 25'(7.6m) in length.
K1797-50 Consists of a 14-conductor control cable
extension 50'(15.24m) in length.
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 DH-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 close the current sensor cover.
DH-10
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.
