WATCHMAKER R6 is a precision automatic rotary welding machine for small parts with a maximum turning diameter of 340 mm, a maximum static load of 25 kg, and 800 mm between the spindle flanges. EWR WATCHMAKER machines are suitable for PLASMA AC/DC and TIG AC/DC welding, but not for MIG/MAG welding.
The machine is designed for precision manufacturing of lightweight machine components, measuring and laboratory equipment, and other small, precise parts. Its precision and well-engineered design deliver welding results comparable to those of conventional single-purpose machines. Precision construction and factory alignment with a maximum deviation of 0.2 mm measured at the spindle flange edges support welding of small, precise parts. This tolerance applies to the machine's factory alignment at this measurement point. The spindle through-holes also allow welding of tubular and rod material or weld-root protection with inert gas.
The tailstock can be equipped with its own drive synchronized with the main spindle; both spindle drives are backlash-free. The stepper motor drives a precision planetary gearbox, which transmits motion through a belt and gear wheels with transverse teeth. The main spindle and tailstock have identical standardized flanges, each 125 mm in diameter with a 28 mm through-hole.
Tailstock pressing uses linear motion through a drawbar, with precise mechanical adjustment of the pressure force using a nut and control lever. Alternatively, the tailstock can be equipped with automated pneumatic pressing using a pneumatic cylinder with the required stroke.
The entire central beam can be tilted from 0 - 90°. Tilting is adjusted manually by a handle through a worm gearbox, allowing precise positioning to optimize the welding process.
The welding arm has a simple pneumatic stroke and three adjustment joints. At the end of the arm, a backlash-free torch support provides +/- 15 mm two-axis adjustment and 90° rotation with position locking in five steps. TIG and PLASMA WELD torch holders are available.
The HST CREATIVE CW 03 cold wire feeder can be fully controlled by the RCS 06 system, with adjustable feeding parameters and reverse wire feeding. The digital Remote Control Mighty Controller is available for increased operating flexibility.
The RCS 06 control system is developed for advanced welding automation. Its functions for circumferential welding include rotary acceleration and deceleration, welding source control with separate programming, advanced welding power regulation, integrated control of the cold wire feeder, program storage, and program sequences.
