Panasonic TAWERS WG4 Review: Specs and Uses of the Integrated Welding Robot System
Updated: 7 days ago
Panasonic TAWERS WG4 is a welding robot system in which the welding power source lives inside the robot controller. The manufacturer does not publish a price. This review covers its specifications, features and uses.
Quick Verdict
TAWERS is Panasonic's signature idea: one controller runs both robot and welding power source, so the arc and the motion are controlled together. The WG4 generation outputs 30 to 350 A for CO2, MAG and MIG, including pulse, with 80% duty cycle on standard processes. It controls six axes simultaneously and up to 27 in total, has functional safety I/O, a multi-core CPU and backlash and deflection correction for accurate high-speed paths. Panasonic cites up to 62% less spatter with one process. A touch pendant with 3D display and IoT interfaces round it out.
