COOPER 620 is a simple automatic rotary welding machine for circumferential welding with a maximum turning diameter of 1000 mm and a maximum static load of 620 kg. The working length, measured between the spindle flanges, ranges from 1500 mm in the basic version to 6500 mm.
The machine has a simple, robust mechanical construction designed for medium loads. The steel frame carries the main base with the integrated drive and control system. The tailstock moves manually along a linear ball guide. The welding torch arm carrier is mounted on the same longitudinal guide, providing a stable platform for positioning the welding arm.
The 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 spindle use standardized flanges, each 250 mm in diameter with a 78 mm through-hole, for mounting suitable universal chucks. HST CREATIVE can also design custom clamping fixtures for specific products, either manually operated or pneumatically actuated and controlled directly by the machine.
Tailstock pressing uses linear motion with a locking segment and an 80 mm pneumatic cylinder with a standard 300 mm stroke, extendable on request.
The machine can be equipped with one or two welding heads with manually controlled longitudinal movement along the machine base. Each welding head is configured for one welding technology. A two-head version can operate the same welding technology simultaneously on both heads. Combinations of different welding technologies or welding sources are available after technical consultation.
The welding arm can use a simple pneumatic stroke with three degrees of mechanical adjustment or, optionally, a numerically controlled Z axis with a +/- 150 mm stroke and the same mechanical adjustment capability. A backlash-free torch support provides +/- 15 mm two-axis adjustment and 90° rotation with position locking. MIG, TIG, and PLASMA WELD torch holders are available, with other versions on request.
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 and supports rotary acceleration and deceleration, welding source control with separate programming, welding power regulation, program storage, and program sequences.
A straightforward design and high durability make COOPER 620 a cost-effective solution. The spindle through-holes also allow welding of tubular and rod material or weld-root protection with inert gas. The RCS 06 control system enables full automation of the circumferential welding process.
