6.2.2 Connecting output cables
(1) Connect the coupling devices
Match the positioning marks (projection) and
insert it, and then turn clockwise to lock.
Use the coupling device suitable to the size of
the applied output cable. Otherwise, it may
cause a cable or output terminal to burn.
(Reference) Cable size to DINSE terminal
(2) Connect base metal cable
Connect the base metal bolt to the base
metal (-) output terminal.
(3) Connect power cable
Connect the torch cable drawn from the wire
feeder to the torch (+) output terminal.
Note
•
Lay the base metal cable
and torch cable as per
the figure on the right
(as straight as possible).
Do not coil the cables
(base metal cable and
torch cable) as per the
figure on the right. Or it
will result in unstable
arc due to its cable
impedance
.

Size of output power cable (Reference)
Select a cable with the situation of welding
operation and rating of the welding power
source in mind, that is, in case of manual weld-
ing, select a cable that operator does not feel
overloaded, and in case of automatic welding,
select a cable that withstands continuous weld-
ing operation.
