What is it?
The Panasonic TAWERS WG3 is not simply a robot with a welding option — it is a fundamentally integrated welding system where the robot motion controller and welding power source share a single control architecture. This eliminates the communication latency between robot controller and separate welding inverter found in conventional welding robot setups, enabling microsecond-level synchronisation between robot motion and arc welding parameters.
Who is it for?
Automotive body assembly, precision component fabrication, and any application where the highest achievable arc quality is the primary specification driver. Manufacturers who have exhausted the quality ceiling of conventional robot-welder combinations and need the step-change improvement that TAWERS integration delivers.

The TAWERS Advantage
Conventional welding robots communicate between robot controller and welding inverter via a fieldbus — introducing milliseconds of latency that limits how precisely arc parameters can be synchronised to robot position. TAWERS eliminates this by merging both systems. The result: the welding waveform can be adjusted in real time based on the robot's exact position and speed, enabling dynamic arc optimisation as the torch moves through complex joint geometries.
How it compares
The TAWERS concept is unique to Panasonic in the standard welding robot market. Yaskawa, OTC, and Fanuc welding robots use external welding power sources with fieldbus communication; only Panasonic offers a fully integrated single-controller system. For maximum weld quality in production, TAWERS is the benchmark.
FAQ
What makes TAWERS different from a standard welding robot?
TAWERS integrates the robot motion controller and welding power source into a single unified system, eliminating the fieldbus communication latency between separate controllers in conventional setups. This enables microsecond-level synchronisation between robot motion and arc parameters — delivering superior weld quality that separate robot-welder systems cannot match.
What is the WG3 generation improvement over WG2?
WG3 adds AI-based arc quality monitoring, more refined waveform control for further spatter reduction, and improved dynamic arc optimisation for faster robot speeds. WG3 extends the arc quality advantage of TAWERS, particularly at higher welding speeds and in complex weld joint geometries.
Does TAWERS WG3 support all arc welding processes?
TAWERS WG3 primarily optimises MIG and MAG welding processes where waveform control has the most impact on quality. TIG welding is supported with external TIG power sources.
Is TAWERS WG3 available as a standalone system or only with specific robots?
TAWERS WG3 is available as a complete integrated system including the TM-series robot arm, the unified controller, and the welding power source — designed as a matched system from Panasonic Robotics.
Which industries benefit most from TAWERS WG3?
Automotive body assembly, motorcycle frame fabrication, precision engineering, and any quality-critical arc welding application where spatter reduction, consistent weld bead appearance, and process monitoring are operational requirements.
