Note) 1. While using RTW5000S, RTW5000H and RTW5000L, are sure that DAIHEN coolant liquid is being
supplied with the water tank (PU-301).
2. The maximum operating current and rated duty cycle are different between CO
2
and MAG welding system.
3. Shock sensor function
Arc welding robots may cause the welding torch to come into contact with workpiece or jig, thus resulting in the
deformation of the welding torch or damage to the robot itself. To prevent such problem, this welding torch
incorporates the shock sensor function that outputs an external force detection signal the instant when the nozzle
portion gets displaced to immediately stop the robot if external force larger than that specified is applied to the torch
tip portion (nozzle portion). This function is incorporated on the assumption that the welding torch comes into
contact with workpiece or jig during robot teaching. Contact of the welding torch with it while in automatic operation
may cause damage to the robot or the torch.
The shock sensor function does not provide any guarantees against the accuracy of aiming point of the torch tip
portion. After the shock sensor gets activated, ensure the aiming point. (For detail, refer to information in Section
5.2.)
4. None of RZ3500S or RZ3500L or RZ3500H accepts stainless wire.
