Depth of Nozzle
The depth of the Nozzle is the distance that the Nozzle Tip is away from the Weld Roller
Pinch Point, which is a very important factor when welding. The optimal distance is 0.25”
to 0.50” away from the Weld Roller Pinch Point. Having the Nozzle too close to the Weld
Rollers may result in the material contacting the Nozzle and burning the fabric, or cause
the nozzle to be dragged into the rollers and cause damage to the nozzle. Having the
Nozzle too far away may result in slower welding speeds. Depress the Drive Foot Switch to
swing Nozzle into place and check the distance. If not properly placed,
(Figure2.11)
release the Drive Foot Switch to swing the Nozzle out and proceed with the following:
1.Adjust the depth of the Nozzle so that it
is 0.25” to 0.50” away from the Weld
Rollers by turning the Depth Adjustment
Knob.
(Figure2.12)
a. clockwise to adjust the Nozzle in
toward the Weld Rollers.
b.counterclockwise to adjust the
Nozzle back away from the Weld
Rollers.
2.Depress the Drive Foot Switch to swing
Nozzle into place and Check to see if the
proper depth adjustment of the Nozzle
has been made.
(Figure2.13)
Repeat
steps 1 and 2 until correct.
