The AVC-5 Arc Voltage Control System has an accuracy of ± 0.1 volts, providing precise and consistent torch to work distance. This high accuracy compensates for tungsten erosion on long automated applications such as tube and pipe mills, keeping the weld penetration and heat input consistent throughout the length of the weld. Because of the high demand for throughput from a tube or pipe mill where welding speeds are quite often in excess of 10 feet (3 meters) per minute, the AVC-5 system removes the torch-to-work distance responsibility from the operator. As welding technology advances and weld speeds continue to push the envelope, our AVC-5 System will be at the forefront of maintaining torch height accuracy.
AVC-5 Control unit features a microcontroller-based unit with advanced capabilities in a simple-to-operate package. Capable of welding in AC and DC applications, the system can be used to weld mild steel, as well as many alloys. The system is hardened against High-Frequency damage and can be used in continuous High-Frequency (HF) AC welding applications. In addition to High-Frequency (HF) Arc starting capabilities, the AVC-5 System offers non-HF starting method known as Lift-Start™, taking full advantage of newer welding power source’s technologies.
One control unit works with either of our AVC drive assemblies. Our standard drive assembly is our most common drive with 6.5 inches (16.5 cm) of stroke and a 40 pound (18 kg) lifting capacity. It easily stands up to the harsh GTAW and PAW welding environments. If physical constraints exist in your welding area and our standard AVC Drive assemblies won’t fit, our Compact AVC Drive Assembly will. The Compact AVC Drive assembly is designed to fit inside of pipe and other small areas such as a weld box on a tube mill. Our Compact AVC Drive Assembly is also capable of lifting 40 pound (18 kg), but with a much smaller stroke of one inch (2.54 cm), making it ideal for tight spaces.
The AVC-5 Arc Voltage Control system can be configured to become the master weld sequence controller for a welding station. Controlling the welding power source, carriage control / rotation device and other components of the welding station eliminates the need for costly PLC equipment and programming. Add our AVC-5 system to your existing equipment and you can obtain higher welding speeds and better weld quality with a relatively small capital expense. The system typically pays for itself in six to eight months.
The control Unit can also be used with older drive assemblies built by Cyclomatic, which include the Standard AVC-3 and Standard AVC-4 Drive assemblies and the Compact AVC Drive assembly, provided these drive assemblies are in good working order.
