There is the danger of crush injuries between the machine tables resp. the
clamping tools,
Do not reach in-between the clamped pipe ends.
Do not reach or tread in-between the clamping tools / machine tables with pipe
ends still to be clamped.
Do not touch the guiding rails of the machine.
Do not hinder the moving tables.
Do wear safety gloves as protection against burning.
The heating element surfaces are to be clean and, above all, free from grease.
Therefore they are to be cleaned with non-fraying paper and detergent (e.g. PE -
cleaner) before every welding or if they are dirty. The anti-adhesive coating of
the heating element has to remain undamaged in the working area.
Clean the heating element only in cold condition – danger of inflammation
caused by cleaning agents.
Activate machine at the main switch, heating element and planer are to be out of the welding
area in basic position, if necessary move into basic position with <joysticks 5 + 6> to
.
The installation of the reducer inserts is made according to the outer diameter of the pipe to be
welded (chapter: 1.7) and the clamping tools are adjusted to the respective angle (chapter:
4.7.1 + 4.7.3).
Set pipe data and machine type at the SPA (70031 without additional cylinder or 70032 with
additional cylinder) (chapter:
Fehler! Verweisquelle konnte nicht gefunden werden. ).
In case the heating element has been deactivated with <switch 3>, switch it on.
Heat-up the heating element onto welding temperature.
As soon as the welding temperature has been reached you can start the welding cycle.
6.1. How to insert and clamp the pipes
Move planer into the machine, <joystick 6> on: (chapter: 4.2.1.
Slowly close the machine tables, <joystick 13> on: until a gap of 20-50 mm is reached
between planer and leading edge of the clamping tools.
Open clamping tools, for this purpose detach clamping nuts and move out spindles. When
using machines with clamping cylinders (option) you must release them, <joysticks 7 + 9> on:
.
Open left and right clamping tool with <joysticks 7 + 9> on:
Insert pipes into the clamping tools in a way that they butt against the planer. Use WIDOS
roller stands for the aligning in case of long pipe ends.
It is indispensable that both pipes are clamped with a constant overhang.
Close clamping tools with <joystick 7 + 9> on: .
Tighten both clamping tools with the spindles and pressure discs. When using machines with
clamping cylinder (option) you must tighten them, <joysticks 7 + 9> on:
.
