LINEAR DRIVE - ADJUSTMENT OF WEIGHT COMPENSATION
This feature enables the adjustment of minimum vertical downward force when the nozzle
touches the work piece while getting the initial position.
The plasma torch must be mounted, the cable and the hose package must be clamped. The cable and
hoses outside must be flexible so the sliding part of the LINEAR DRIVE is not hindered.
If the drive is hindered from moving, do not secure the cables and hoses in the clamp. If necessary use
an extended bracket.
1. Rotate the knob Weight Compensation clockwise until a slight lift up of the torch occurs. You
may hear a high pitched tone.
2. Rotate the knob counter clockwise until the tone stops and the lifter slide rests lightly on its
lower stop.
3. Check the weight compensation:

release it again.
The lifter slide must rest
lightly on the lower stop.
Adjust pressure with the
weight compensation knob.
