180M Weld Head. Chapter 1 describes the equipment, Chapter 2 describes installation, Chapter 3
describes operating procedures so you can run the weld head safely and efficiently, and Chapter 4
describes maintenance and troubleshooting procedures.
Miyachi Unitek THIN-LINE Series 180M Weld Heads are production line heads having a narrow
vertical profile. They are characterized by low inertia, force fired operation. Depending on the model,
their primary operational features allow them to be used in a wide variety of precision resistance
welding applications.

4.44 cm (1.75 inch) width (actual head module)

3.17 cm (1.25 inch) stroke

22.2 to 445 N (5 to 100 pound) force range

15.32 to 25.72 (6.031 to 10.125 inch) throat depth
Bearing life is designed for a minimum of 20 million operations when the head is used according to
specifications.
The design of the aluminum extrusion mounting system and main shaft ensures that the offset electrodes
do not slide from side to side more than 0.381 mm (0.015 inch) at 445 N (100 pounds). The four
mounting holes on the head spine allow you to easily incorporate the head into your custom welding
machines. In addition, you can modify the aluminum extrusion used for the base of the head to
accommodate your custom fixtures and tooling.
Precision Welding
The weld heads excel in their ability to deliver repeatable weld force and electrode placement on your
parts. The low inertia, lightweight design ensures fast dynamic response. This allows the top electrode
to follow the minute expansion and contraction of the weld joint as it heats and cools. A "differential
motion" force-firing system triggers the weld energy power source at the precise moment when the
electrodes reach the preset firing force applied on the work pieces.
Rugged construction, linear ball bearing bushings, and an over-sized anti-rotation system provide perfect
in-line electrode travel, which assures smooth vertical travel of the upper electrode arm. This
system
minimizes the "wiping" (side-to-side sliding) action of the electrodes during welding, even at maximum
force settings.
