K3573-2 - Lincoln Electric IRB1660ID Feeder Mounting Bracket for 4R100/4R200

Technical Overview: K3573-2 Robotic Feeder Interface

The Lincoln Electric K3573-2 is a specialized mounting bracket assembly engineered specifically for the integration of Lincoln's 4R100 and 4R200 Robotic Wire Feeders onto the ABB IRB 1660ID robotic arm. In automated welding applications, the stability of the wire feeder relative to the torch and the robot axis is paramount for maintaining consistent arc characteristics and wire stick-out. This bracket provides the necessary mechanical interface to secure the feeder unit to the robot's upper arm or shoulder, depending on the specific configuration required for the cell.

The "ID" in IRB 1660ID stands for Integrated Dressing, meaning the process cables are routed inside the upper arm and wrist. This design reduces cable interference and wear but requires specific mounting solutions that do not obstruct the internal routing or the robot's range of motion. The K3573-2 is designed with this geometry in mind. It positions the 4R100 or 4R200 feeder optimally to minimize the length of the conduit between the drive rolls and the torch, thereby reducing friction and improving wire feed response, especially when using softer wires like aluminum or during complex weaving patterns.

Constructed from high-grade industrial materials, the bracket is built to withstand the high acceleration and deceleration forces typical of modern robotic welding cycles. It resists flex and vibration, which are common culprits in wire feed issues such as burn-back or bird-nesting. The mounting points are precision-machined to match the bolt patterns of the ABB arm and the Lincoln feeder, ensuring a hassle-free installation that requires no drilling or tapping. This OEM fitment ensures that the center of gravity remains within the robot's calculated payload parameters, preventing overload errors or path deviation.

For maintenance and MRO professionals, utilizing the K3573-2 simplifies feeder serviceability. The bracket holds the feeder securely while allowing access to drive rolls, guides, and pressure arms for routine changes and cleaning. It is an essential component for any fabrication shop utilizing the specific combination of Lincoln Electric Power Wave systems and ABB robotics. Ensure your welding procedures meet the highest standards of repeatability and reliability by securing your wire delivery system with the correct, manufacturer-specified mounting hardware.
