Note
About cable-laying
• Lay the base metal cable
and torch cable as
shown in 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
Note
Size of base metal cable and output power cable
(Reference)
For power cable, select a cable with the
situation of welding operation and rating of
the welding power source in mind, that is, if
manual welding is used, select a cable that
operator does not feel overloaded, and if an
automatic welding is used, select a cable that
withstands continuous welding operation.
