Large reduction inserts:
•
They are mainly used for a good tightening and are generally mounted on the inner clamping
devices.
•
Super large reduction inserts have a specially high guidance quality and are mainly used
during the welding of fittings with long legs which can only be clamped with a single clamping
device.
5.3. Automatic heating element (Optional)
For inserting the heating element, please use in any case the handle provided for this purpose (A
and B).
Pressing the handle (B) in the direction of the heating element plate will lock or release the
heating element in the protection box or on the basic machine. The rollers (D) have to be
supported on the guideway (E) before the heating element is locked by releasing the handle (B).
For welding, the heating element is pressed downwards by means of the handles (C) (sledges
must not be opened completely).
After expiration of the adjusting or heating time, the heating element is unlocked by opening the
sledge and is moved automatically out of the basic machine.
