Selection – Welding Cable
Select the cable with proper gauge, based on the allowable amperage and the
length, per the table shown below.
The welding capacity is to reduce if the small gauge cable is used.
< Caution >
•
Welding cables should be used unstrained. When the welding cables are used in
swirl, the welding capacity is to reduce.

Polarity
There are two welding output terminals,
『＋ ＋ ＋ ＋』
and
『－ － － －』
.
Select the polarity according to the operation, referring to the table below.
< Caution >
•
Follow the instruction of the welding rods, the polarity of which is specified.
•
If connected by different polarity and the same work is simultaneously used by two
types of machine, the voltage between folders may receive an electric shock.
That one operator has two folders absolutely should avoid.

Connection – Welding Cable
Danger : 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 a welding cable to a welding output terminal.
④
After connecting cables, be sure to close output terminal covers and fit it with
the bolt.
