8-2. Polarity
There are two welding output terminals, "
+
" and "
-
".
Select the polarity according to the operation, referring to the table below.
<Note>
•
Follow the instruction of the welding rods, the polarity of which is specified.
8-3. Connection – Welding Cable
Warning: Electric Shock
•
Before connecting or disconnecting a welding cable from welding output terminals,
stop the engine, and remove the engine key. A person performing should always
keep the key.
1) Stop the engine.
2) Connect a welding cable to a crimping terminal, a welding rod holder, and a
material holder.
3) Connect the welding cables to the output terminals per the table below.
4) Close the output terminal cover, after finishing connections.

•
Be sure to crimp a crimping terminal to a cable and connect the cable to welding
output terminal. Otherwise, welding output terminals may burn out by the heat
caused by insufficient connections.
•
Do not use a cable without a crimping terminal. If you use the cable, the insulation
is peeled off partly, to bind to an output terminal, the output terminal may burn out
by the heat caused by insufficient connections and also a bare part of the cable
may touch the bonnet to short-circuit.
