OUTPUT CONNECTIONS
Refer to Figure A.2 for the location of the output terminals.
A quick-disconnect system using Twist-Mate
TM cable plugs is
used for the welding cable connections. The electrode and
work cables will require these plugs. Refer to the relevant
instructions following for more information on connecting the
machine for either welding process.
OUTPUT CONNECTION FOR STICK
WELDING
First determine the proper electrode polarity for the elec-
trode to be used. Consult the electrode data for this infor-
mation. Then connect the output cables to the output termi-
nals corresponding to this polarity. For instance, for DC(+)
welding, connect the electrode cable (which is connected to
the electrode holder) to the “+” output terminal and the work
cable (which is connected to the work clamp) to the “-” out-
put terminal. Insert the connector with the key lining up with
the keyway, and rotate approximately 1/4 turn clockwise;
until the connection is snug. Do not over tighten.
OUTPUT AND GAS CONNECTION
FOR TIG WELDING
This unit does not include a TIG torch, but one may be pur-
chased separately and used with these units to do TIG
(GTAW) welding. The Lincoln LA-9 (K859-1 or K859-5 only
with no gas valve) or LA-17 and LA-17V (K860-1 or K860-5
without gas valve and K860-9 or K860-13 with gas valve)
are recommended for use with these machines for this pur-
pose; however, any similar TIG torch can be used. To attach
the Twist-Mate Plug to a Lincoln Torch, slide the rubber boot
onto the torch cable (enlarge the boot opening if necessary),
screw the fitting on the torch cable into the brass connector
snugly and slide the boot back over the brass connector.
Turn the Power Switch “OFF”. Connect the torch cable quick
connect plug into the DC- Output Receptacle on the front of
the welder and turn it clockwise until it is tight. This is a
quick connect terminal and also provides the gas connection
for the shielding gas to the torch.
To avoid receiving a high frequency shock, keep the TIG
torch and cables in good condition.
__________________________________________
Next, connect the work cable (which is connected to the
work clamp) to the “+” output terminal in the same way.
The machine can easily be switched between stick and TIG
welding at any time by simply swapping the stick (electrode)
and TIG (torch) cables, and reversing the connection polari-
ty if required.
