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.
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 25ʼ(7.6m) in length.
K1797-50 Consists of a 14-conductor control cable
extension 50ʼ(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.
INSTALLATION
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.
