摘要

A heating device (2) is fastened axially to a frame (1) provided with guides (4), and an axially adjustable tube-clamping device (3) is arranged on either side of said heating device. A heating device (2) is provided for each diameter of pipe to be welded, and when placed on the guides actuates an associated electric switch (11) by means of a pin (6). A welding program corresponding to this tube dimension, which is located in a program control (12) and which determines the quantity of heat supplied, is acknowledged by means of this switch (11).
