8. Hot Wedge

8.1 Wedge Types

There are two different types of wedge; which one is used depends on the intended purpose and the required speed.
The engraving on the wedge holder (3) indicates the type in question. The number indicates the welding width. The
maximum possible welding speed depends on the welding holder that is mounted. When the wedge holder is selected
(Chapter 9.6), the possible speed of the wedge in question is automatically limited. Always make sure that you mount
the right wedge (22) on the right welding holder.
8.1.1 3D Wedge (3-Dimensional Wedge)
This wedge can be used at up to 10 m/min. This wedge has a small wedge/material contact surface. This means that
the material can be guided effectively and the guiding resistance is lower. This wedge is ideal for cases such as curves,
products with complex shapes, and applications where a maximum speed of 10 m/min is sufficient.
8.1.2

HS Wedge (High-Speed Wedge)

The larger wedge/material contact surface optimizes the transfer of energy into the material. The maximum speed is
30 m/min.
This type of wedge is primarily suited to straight, efficient weld seams.
