6.1 Connecting output cables for TIG or SPOT welding
This section explains the connection in case of using a
special torch.
* In case of using other torches and/or extension cables:
see section “Configuration: Peripheral equipment”.
• Connect the cables in the order shown in the following
table referring the figure on the right.
• The polarity relation between the torch and base material
is electrode minus (DCEN).
Note
About the base metal cable
Connect the attached fingertip joint (D1XSK50) to the
base metal cable that is a welding cable or cabtire
cable (excluding the class-1 cabtire cable and vinyl
cabtire cable) of 38mm
2
or more.
Important
The installation shall be done by qualified installation personnel and should conform to all national
and local codes.
Type and capacity of protection devices, such as breaker and fuse, to be applied should conform to

shock, burn injury and so on.
To prevent physical accidents like an electric shock,
burn injury and so on, make sure to observe the followings.
Make sure to turn off the switches of this product and the distribution box before starting connections.
Do not perform any connection work with moistened hands.
Make sure to insulate all bare current-carrying parts like joints and so on by tape, etc.
Do not strain cables, or let them make contact with the welding arc area.
For safety reasons, make sure to provide this product and base material with grounding work done by qualified
electricians.
* In case of using a water coolant, the water coolant should also be provided it with grounding work.
CAUTION
Observe the followings to prevent a fire caused by overheat of cables.
Use cables at least with specified thickness.
Fasten all cable connections securely.
