3.5 Tool constant settings
Tool Length Automatic Setting (2-point tool length setting)
In order to easily set a new tool length when the shape of a tool is deformed, 2-point tool length setting
function is prepared. In the case where the torch interferes during operation, or the torch is changed with a
new one, be sure to use this function. By use of this function, the tool length after deformation is automatically
calculated. It is necessary to teach the task program before and after tool deformation as a calculation
program in advance.
1 First, it is necessary to teach the task program with the tool before deformation.
Carry out teaching (1 step) the task program which the attached tool tip (to
which a sharp end portion is attached too) is likely to target, to the sharp end
fixed to the ground.

2 Next, it is necessary to teach the task program with the tool after deformation.
Carry out teaching (1 step) the task program in the same manner as in the
above 1.
>>Set the tool posture same as that taught in the above 1.

setting> key.
>>The 2-point teaching tool length automatic setting screen is displayed as shown
below.
4 If a different screen is displayed, press the <2-Point Length Set> key.
5 Move the cursor on the program of the reference point before conversion, and
input the program number prepared in the above 1 (for example, No.1), and
press [Enter] key.
6
Move the cursor on the step of the reference point before conversion, and input
the step number prepared in the above
1 (for example, No.1), and press [Enter]
key.
