‘This invention relates to welding devices and
a guide wheel roller which engage the work at
a point remote from the point of contact of a
tool therewith and which roller and wheel are so

provides an improved apparatus for controlling

Heretofore welding devices, such for example,
as the unionmeltr welding machine have been ‘em
ployed in welding operations wherein the welding
- electrode is guided along the work in a prescribed
manner, by means of suitable guide wheels or 10
similar apparatus. These guide wheels may bear
