3.2.3 Welding
Risk of crushing! Always maintain a safe distance from the machine when
moving clamping tools and pipes together! Never reach into the working area!
 Put heating element between the workpieces.
 Move pipe ends together and apply required adjusting force.
 As soon as the required bead height is reached evenly over the entire circumference at the
ipe ends, reduce the force to the corresponding preheating force (near 0). It must be en-
sured that the workpiece ends abut evenly to the heating plate.
 After finishing the preheating time, move pipe ends apart, remove heating plate and move
pipe ends together again within the max. change over time. Increase force as lineary as
possible to the corresponding joining force within the build up pressure time. The joining
force must be maintained with a tolerance of

6,66% during the entire cooling period.
 At the end of the cooling period release the spring via handwheel. Unclamp and take out the
welded tube sections.
All welding parameters can be found in the enclosed welding tables.
3.2.4 Welding of Segmended Bends
 Loose the screws in the base of the main clamps. Turn main clamps until the wished angel
on the scale is shown. Tighten screws again.
 Cut pipe ends in the required angel and clamp them in the main clamps.
 During trimming take care that the pipe ends are in the center of the trimmer disc.
 This can be adjusted by loosen the screws at the bottom of the trimmer support pushing or
pulling the trimmer in the center of the pipe ends and tighten the screws again.
 Use the depending Welding table.
 The angel shown on the welding table means the total angel of the welding.
 Example: 30° = 2 x pipe end with 15° each
Follow the ins
truction of „3.2.3 Welding
3.2.5 Putting out of operation
 Switch off the heating element.
 Unplug the heating element.
 Store basic machine and tools into transport case.
Let the heating element cool or stow it in such a way that no adjacent materi-
als can be ignited!
3.3 General requirements
As weather and ambient conditions can seriously effect welding procedures and joints, it is es-
sential to duly observe national welding guidelines and ordinances, e. g. DVS Guideline 2207,
Sections 1, 11 and 15.
Welding requires continuous and due supervision and monitoring!
3.4 Important information on welding parameters
For welding parameters such as temperature, pressure and time, consult your national welding
guidelines and ordinances, e. g. DVS Guideline 2207, Sections 1, 11 and 15.
