Notes on flexible torch bodies

General

The flexible TIG torch bodies can be bent in all directions and thus individually adapted
to a wide variety of situations and applications.
Flexible torch bodies are used, for example, in cases of limited component accessibility
or difficult welding positions.
However, the material of a flexible torch body is weakened with every change in shape,
so the number of times it can be bent is also limited.
Bending and number of bends are explained in the following sections.
Definition of A bend is a one-time change in shape that deviates from the original shape by at least
torch body ben- 20°.
ding
A smallest possible bending radius has been defined so that the bending action does not
occur at a few certain points but as uniformly as possible over a long length.
The bending radius must not be less than this.
The smallest possible bending radius is 25 mm / 1 inch.
A bend must not exceed a maximum bending angle.
The maximum bending angle is 45°.
Bending back to the original shape is considered a bend in its own right.
