The base body of the KAH 412 automatic welding head consists of a section of
square aluminium.
All supply lines (welding current cable, control cable, compressed air lines) are
plugged into the
connection casing (E)
.
Located on the front of the KAH 412 automatic welding head is the feed tube, which
can be quickly changed via the pushbutton locking system. The infeed (manual or
automatic) of the welding elements takes place via the feed tube in the slot piston
with guide sleeve to the chuck. The plunger cylinder integrated in the piston (moun-
ted backlash-free with linear ball bearings) pneumatically moves the welding ele-
ment through the chuck to the welding position.
The entire adjusting mechanism for lift and spring force is located above the connec-
tion casing (E). The lift adjustment can be read via a digital measurement system.
The spring pressure is displayed directly via a scale.
The KAH 412 automatic welding head is secured to the Z-axis (either pneumatically
or by means of a motor) via the prism quick-change system attached to the rear.
The type plate is located on the front of the welding head.
