Adjusting the height of lift

The height of lift is the distance the stud is lifted from the workpiece during the welding
process. This distance is required for igniting the arc. Determination and adjustment of
the lift is the same for welding with both support tube and ceramic ferrules. The height
of lift always depends on the stud diameter.
Appendix A /6
How to determine the height of lift
• Adjust function "lift test" at the stud welder.
• Place welding gun on the workpiece
• Press gun switch. Stud holder (2) and stud (3) are lifted from workpiece (1).
The lift is adjusted with the help of adjusting screw (6) located at the back of
the welding gun
How to adjust the height of lift
• Insert screwdriver into the groove of adjusting screw (6) located at the back
of welding gun and adjust by turning the screwdriver to the left or to the right,
until the required height of lift is obtained. Turning to the left increases the
height of lift, turning to the right decreases the height of lift. One turn of the
adjusting screw corresponds to approx. 1 mm. After adjustment, check the
height of lift and correct, if necessary.
With the PH-3N stud welding gun, the height of lift can be adjusted by turning
the adjusting cap (6) at the rear of the welding gun to the left or to the right,
without using any tools.
