<p>In a self-driving resistance welding carriage with independent friction wheels and a mechanical drive assembly and an independent welding device with at least two, pref. cooled welding friction wheels, the couple between drive elements and the workpieces, e.g. plates, is increased by providing the drive device with four inclined friction wheels to improve shielding of the moving appts., and stop rollers which are easily moved from their blocking posn. ensuring accurate positioning.</p> |
