◊ Calculation of the value to program to get a
required linear travel speed
The table give a reference number R30 for the iden-
tifi cation of every standard welding head. The ref-
erence number contains a letter and a three digit
number. It has to be correctly introduced during pro-
gramming to assure the proper functioning of the
movements.
In order to get a required linear travel speed VL for
a tube diameter D, the value to program VP (V32 for
single travel speed, V33 for step pulse travel speed)
has to be calculated with the formula:
- VP = C x VL/D
C is a factor due to every type of welding head and
given in the last column of the tables.
Example :
Welding head MW 65: C = 60 (see table enclosed
welding heads).
Required linear travel speed VL = 152.5 mm/min
(6 IPM).
Tube OD = 25.4 mm (1").
VP = 60 x 152,5 mm/min / 25.4 mm (6 IPM/1").
VP = 360 = V32.
R30 = Reference number of the welding head
