Weld Head Installation
1. Turn the clamping knob counter clockwise
until the track rollers are fully separated.
Ensure that the clutch latch is in the disen-
gaged (up) position.
FIGURE 10 – LATCH AND KNOB
2. Lift up the tractor by the handles (not the
wire feed motors), place the tractor on top
of the track with the torch perpendicular to
the track.
3. Turn the clamping knob clockwise to close
the tractor onto the rails, ensure the weld
head is secure but still loose enough to
move fluidly. Over-tightening the clamping
knob can result in a small jerk during the
transition over the track joint, as well as ex-
cess motor stress.
4. Roll the tractor to the desired starting posi-
tion on the track and engage the clutch
latch.
5. Verify that there is no side to side or for-
ward/backward motion before beginning the
weld. Side to Side motion can be adjusted
out by tightening the Clamping knob. For-
ward and back motion can be adjusted out
by turning the clutch latch clockwise. Do
not over-tighten.
