(8) To teach a program with the torch evacuated from the weld wire after the completion of welding,
pull the torch obliquely upward so that the shock sensor will be activated even if the wire and
base metal are deposited together.

(9) The shock sensor may cause a slight deviation from the teaching point at the torch tip (i.e., torch
aiming point). (If the shock sensor gets activated, recheck for the torch aiming point with the torch
gauge.)
(10) On the RZ Series, the power supply points are located inside the tip holder. Consequently, note that,
the power supply points become farther from the torch in comparison to conventional torch, thus
resulting in lower welding current (in case of constant-voltage control) to cause changes in welding
conditions.

For reference

The RZ Series torches increase resistance heat generation due to farther power supply
points, and thereby can melt more weld wire, thus making it possible to provide proper arc
length (arc weld voltage) at low currents.
(11) Precautions for replacement of rear tip body, pressurizing shaft, and coil spring
to replace the rear tip body, pressuring shaft, and coil spring, do not dismount these parts with the
rear tip body pointing downward. Doing so may cause the coil spring to come off and be missing.
