1. Proper use 
The FlexTrack 45 is a rail carriage designed to establish groove and fillet welds with 
or without oscillation using MIG/MAG or CMT torches with handle diameter of 
16-35 mm. The carriage can be fixed on straight, flexible orbital, and orbital rails. 
It  can travel horizontally, vertically, and orbitally, which is enable for welding in 
almost all positions.  
 
IMPORTANT! When using vacuum bridges, the workpiece must not be preheated! 
 
 
1.1  Secure carriage against falling 
In vertical operation, the rail construction must be secured with a load securing 
device with a locking function, to prevent it from falling. The load securing device 
must be designed for the total weight of the rail construction with carriage. The 
manufacturer accepts no liability for any damage to persons or property, resulting 
from vertical use of the carriage without a load securing device. 
 
 
1.2 Improper use 
Any use of the machine other than for its intended purpose shall be deemed 
improper use. This includes: 
 
  Using flexible (unreinforced) rails on flat surfaces 
  Using vacuum bridges on preheated workpieces  
  Use over head 
  Use as lifting tool (Transporting or maneuvering loads, animals, people) 
  Standing on the machine or using it as a work platform 
  Use as a storage surface for tools 
  Use outside the permitted technical operating limits 
  Use in hazardous areas
