INVERTER ARC™ 230
A-3
OUTPUT CONNECTIONS
A quick disconnect system using Twist-Mate™ cable
plugs is used for the welding cable connections.
Refer to the following sections for more information on
connecting the machine for operation of stick welding
(SMAW) or TIG welding (GTAW).
ELECTRIC SHOCK can kill.
• Keep the electrode holder and cable
insulation in good condition.
• Do not touch electrically live parts or electrode
with skin or wet clothing.
• Insulate yourself from work and ground.
• Turn the input line Switch on the INVERTER
ARC™ 230 “off” before connecting or discon-
necting output cables or other equipment.

STICK WELDING (SMAW)
First determine the proper electrode polarity for the elec-
trode to be used. Consult the electrode data for this
information. Then connect the output cables to the out-
put terminals of the machine for the selected polarity.
Shown here is the connection method for DC(+) welding.
(See Figure A.1)
Connect the electrode cable to the (+) terminal and the
work clamp to the (-) terminal. Insert the connector with
the key lining up with the keyway and rotate approxi-
mately 1/4 turn clockwise. Do not over tighten.
For DC(-) welding, switch the cable connections at the
machine so that the electrode cable is connected to (-)
and the work clamp is connected to (+).

WARNING
230V INPUT
The INVERTER ARC™ 230 is provided with a 230V
cable, 6.0ft.(1.8m) in length, with a 50 Amp (NEMA 6-
50P) plug molded onto the cord.
The rated output of the INVERTER ARC™ 230 is
available when connected to a 30A branch circuit.
When connected to a branch circuit with lower ampac-
ity, lower welding current and duty cycle must be
used. Other loads on the circuit and fuse/circuit break-
er characteristics will affect the available output.
TIG WELDING (GTAW)
This machine does not have a built in Gas Solenoid
so a one piece gas valve TIG Torch is required. A
K960-2 Twist-mate TIG Torch adapter is also required.
Refer to the accessories section for more information
about TIG Torches and required Twist-mate adapter.
Most TIG welding is done with DC(-) polarity shown
here. If DC(+) polarity is necessary switch the cable
connections at the machine. (See Figure A.2)
Connect the torch cable to the (-) terminal of the
machine and the work clamp to the (+) terminal.
Insert the connector with the key lining up with the
keyway and rotate approximately 1/4 turn clockwise.
Do not over tighten. Finally, connect the Twist-mate
adapter gas hose to the gas regulator on the cylinder
of gas to be used.
