The PIINC BW350 Auto Bore Welder is a portable internal diameter (I.D.) welding system designed for on-site repair of worn or damaged bore surfaces. With an internal diameter welding range of 40–450 mm and a welding stroke of 208 mm, the BW350 provides a practical solution for restoring specialty parts and equipment components, helping reduce the need for costly component replacement.
Designed for both vertical and horizontal welding positions, the BW350 can work directly with a compatible MIG wire feeder machine. To simplify integration, the bore welder can be supplied with a connection compatible with your existing welding machine, including European, Panasonic, Miller, Lincoln, and other specified connection types.
The BW350 Auto Bore Welder is particularly well suited for use with PIINC TDG50, TDG50IMP, and TDG60 portable line boring machines. Combining line boring and bore welding in one setup can help streamline repair work, reduce equipment downtime, and improve on-site maintenance efficiency.
The BW350 supports internal diameter welding from 40 mm to 450 mm, making it suitable for repairing a range of bore sizes in industrial equipment and specialty components.
The system can perform internal diameter welding in both vertical and horizontal positions, providing flexibility for different workpiece orientations and repair conditions.
The portable Auto Bore Welder can work directly with a compatible MIG wire feeder machine. Connection options can be matched to the welding equipment specified by the customer, helping facilitate integration with an existing welding setup.
Supported connection types may include:
European
Panasonic
Miller
Lincoln
Other specified connection types
Connection compatibility should be confirmed when ordering.
The BW350 enables internal bore welding directly at the equipment location. On-site repair can help avoid unnecessary component removal and transportation, providing a practical alternative to costly replacement when the component is suitable for repair.
The BW350 is designed to work with PIINC TDG50, TDG50IMP, and TDG60 portable line boring machines. This combination supports line boring and bore welding within one setup, helping simplify the repair process and reduce repeated setup work.
The system is designed for convenient setup by one operator, helping simplify preparation for on-site bore welding tasks.
By supporting on-site bore repair and helping avoid unnecessary component replacement, the BW350 can contribute to lower repair costs and improved equipment availability.
