(2) -4. Connecting the torch
WARNING
Use the dedicated torch cable.
Fix the cable connecting part securely. Do not extend the cable more than the necessary
length. The cable length should be 10 m or less. A large current will flow and a high voltage
of about 10 kV will be applied at a start of welding.
If a cable with an insufficient capacity or a cable with a low withstand strength is used, a fire or
electric shock may occur.
Do not use a deteriorated or damaged torch cable.
Put a cable cover on the contact portion with the moving part or human body so as not to
damage the torch cable. If a cable with a deteriorated or damaged cover is directly touched or
if the metal part with which the cable is brought into contact is touched, an electric shock may
occur.
IMPORTANT
To avoid a malfunction due to noise, do not bundle the torch cable together with the
input/output signal cable, input cable and grounding cable. Perform wiring of each cable with
a separation of 100 mm or more.
In the following, how to connect the torch will be described.
Connect the torch cable to the torch terminal provided on the rear panel according to the following
procedure.
1. Pass the torch cable through the cable gland (upper right) of the terminal cover.
