4.2 Description of function
Using the welding bench, door and window elements of perfect quality can be pro-
duced in a time-saving manner. In principle, the bench is a quickly adjustable gauge
that guarantees that even single elements can be rationally processed.
The JANSEN welding bench has four supporting plates (planar) with clamping devic-
es mounted on adjustable slides. The supporting plates are parallel to each other, the
stops are arranged at exact angles of 90°. These plates have been given special sur-
face treatment that repels weld spatter. The previously mentioned slides can be ad-
justed in their width and longitudinal directions by spindles. The digital mass indicator
is thereby used for initial setup of the size of the bench. The effective dimension may
differ by +/- 1 mm from the digital indicator due to the production tolerances of the
spindle.
The profiles are horizontally clamped against an outside stop onto four plane sup-
porting plates of the welding bench. With the "inside stop" version, the inner profile
lug can be additionally supported by a fixture. After fixing the mitre perfectly, the pro-
files are vertically fixed by a clamping device. The arrangement of the supports also
allows the frame to be riveted at the underside of the profile.
The stable stops and clamping devices prevent the construction from slipping during
the welding process; subsequent alignment of the elements is therefore usually not
required.
The welding bench can be rotated clockwise and counterclockwise by a motor (hori-
zontally). It is operated by a footswitch.
