8. Description of carriage with oscillation 
The carriage with oscillation consists of a drive system, pressing roller units, 
oscillation, cross slide, torch holder, remote control, and a control box. The drive 
system comprises a gear motor that drives the gear. The fixed roller unit lever and 
rotational roller unit lever are used for fixing the carriage by clamping four hardened 
steel rotational rollers to the guide using disk springs. 
 
The clutch enables the gear to engage or disengage with the holes of the hardened 
spring steel rail guide. The cross slide enables for precise control of the torch position 
in both horizontal and vertical axis. The carriage travels according to parameters 
programmed on the controller. The controller with the magnetic foot can be 
positioned on the carriage, on the pipe, on flat ferromagnetic surfaces, or can be hold 
in hands. The controller enables for programming and adjusting all welding 
parameters as well as positioning of the torch during welding. The control box 
assures communication between the controller and the welding device.
