SECURITY CAUTIONS
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 yourseld from work and ground.
• Turn the input line Switch on the arcweld machines "Off"
bedore connecting or disconnecting output cables or other
euipment.
CAUTION
For secure electrical connection, the power source sockets
connecting cable plugs must be tightened. Damage may
occur to the output socket or welding performance maybe
compromised.
To avoid interference problems with other equipment
and to achieve the best possible operation, route all cables directly
to the work. Avoid excessive lengths and do not coil excess cable.

OUTPUT CONNECTIONS

A quick disconnect system using Europe quick 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.
STICK WELDING (SMAW)
First determine the proper electrode polarity for the electrode to be
used. Consult the electrode data for this information. Then connect
the output cables to the output terminals of the machine for the
selected polarity. Shown here is the connection method for DC(+)
welding. (See Figure B.1)
Connect the welding cable to the (+) terminal 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.
For DC(-) welding, switch the cable connections at the machine
so that the welding cable is connected to (-) and the work clamp is
connected to (+). (See Figure B.2)

TIG WELDING (GTAW)
®
The Arcweld machine does not have a built in Gas Solenoid so a
piece gas valve TIG Torch with gas valve is required. A TIG Torch
adapter is also required. Refer to the accessories section for more
informatin about TIG Torches and required adapter. Most TIG
welding is done with DC(-) polarity shown here.(See Figure B.3)
If DC(+) polarity is necessary switch the cable connections at the
machine.
Connect the torch cable to the (-) terninal of the machine and the
work clamp to (+) terminal. Insert the connector with key lining up
with the key way and rotate approximately 1/4 turn clockwise. Do
not over tighten. Finally, connect the adapter gas hose to the gas
regulator of the cylinder gas.
Stricking arc of TIG operation
When the tungsten electrode touches the workpiece, the short-
circuit current is only 10A. After generating arc, current can rise
to the preset welding current. If the tungsten electrode touches
the workpiece during welding, the current will drop to 10A within
2s, which can reduce tungsten damage and prolong the tungsten
electrode life.
