INSTALLATION
INPUT POWER CONNECTION
Check the input voltage, phase, and frequency supplied to
this machine before turning it on. The allowable input voltage
is indicated in the technical specification section of this man
ual and on the rating plate of the machine Be sure that the
machine is grounded
Make sure the power available at the input connection is ade-
quate for normal operation of the machine.
OUTPUT CONNECTIONS
A quick disconnect system using Twist-Mate cable plugs is
used for the welding cable connections. Refer to the follow-
ing sections for more information on connecting the machine
for operation of stick welding (MMA) or TIG welding
A WARNING
ELECTRIC SHOCK can kill.
• Keep the electrode holder and cable in-
sulation 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
YWA-160"0ff" before connecting or
disconnecting out-put cables or other
equipment.
STICK WELDING (MMA)
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 connec-
tion method for DC(+) welding (SEE FIGURE A.I)
Connect the electrode cable to the (+) terminal and the work
clamp to the (-) terminal
Insert the connector with the key lin-
ing up with the keyway turn clockwise. Do not over tighten
For DC(-) welding, switch the cable connections at the ma
chine so that the electrode cable is connected to (-) and the
work clamp is connected to (+)

TIG WELDING
This machine does not have a built in Gas Solenoid so a one
piece gas valve TIG Torch is required. A TIG Torch adapter
is
also required. Refer to the accessories section in
mvw_yeswelder com for more information about TIG Torches
and required Twistmate 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
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 turn clockwise
DO
not over tighten. Finally, connect the gas hose to the gas reg
ulator on the cylinder Of gas to be used
