Panasonic TAWERS welding robot technology

PANASONIC TAWERS – FULLY INTEGRATED WELDING ROBOT SYSTEM 

Fusion of robots, robot controller, power source and servo wire feed together in one unit: Faster, better and worldwide unique. Everything from one manufacturer. The idea behind TAWERS is based on the “fusion technology” contained in TAWERS, whereby the robot controller is fused with the welding power source controller. All control parameters such as data processing and programming sequences for the welding power source, the wire feed and the robot are combined on a 64-bit CPU PCB. This technology enables up to 250 times faster communication, eliminating virtually any delay in information flow between the individual components.

The result is unique and allows many special functions to increase the quality and productivity of TAWERS, e.g. SP-MAG, lift start and lift end, automatic wire distance control, welding data monitoring, collision detection etc.

ALL IN ONE – NO MORE COMPROMISES

• No separate interface between the robot and the power source.
• Welding parameters are set not via JOB files but directly and flexibly through the teaching pendant.
• Since there is no external welding power source, there’s no need to learn separate controls.
• All settings can be managed via the Windows-based teaching pendant.

ALL FROM ONE – EVERYTHING FROM A SINGLE SOURCE

Panasonic develops and manufactures all key components in-house in Japan:

• Robot manipulator

• Integrated inverter welding power source (TAWERS)

• Servo-controlled wire feeder integrated into the robot arm

• Robot controller unit

• Positioners

• Welding torches

• Software, welding cables, connectors

This harmonized system ensures stable operation and fast, reliable service support.

KEY ADVANTAGES

Integrated CPU – One Control for Both Robot and Power Source
The robot and welding power source are controlled in full synchronization by a single 64-bit central processor. The result: faster communication, more precise welding, and stable continuous operation.

Faster Data Exchange, Less Downtime
The system is 140–250% faster than conventional digital robot controllers. Real-time data exchange reduces cycle times and increases production efficiency.

High Flexibility
A single system can handle multiple welding processes – MIG, MAG, TIG, pulsed, low heat input welding, galvanized sheet welding, brazing, etc. Welding processes can be activated via software.

Specialized Technologies

• Lift Start – For more stable arc ignition

• Lift End – Ensures consistent wire end geometry

• Automatic Wire Stick-Out Control – optional

• Horizontal Seam Tracking – optional

• Touch Sensor – optional

• Arc Sensor – optional

Minimal Spatter
The SP-MAG II software and embedded arc control technology ensure minimal spatter, low heat input, and precise droplet transfer.

Welding Navigation
Built-in software assists in setting optimal welding parameters, making the system easy to operate even for less experienced users.

Cost-Efficient System Solutions
Fewer components, simplified commissioning, and efficient energy use make the TAWERS system a cost-effective solution in the long run.

TAWERS – Multiple Welding Processes, One System

The Panasonic TAWERS system integrates multiple welding processes into a single controller, providing unmatched versatility:

• MIG / MAG / TIG DC

• Normal Pulse / HD Pulse

• SP-MAG I–II (steel, stainless and acid-resistant steel, ferritic, austenitic)

• Aluminum MIG

• Zinc-Tech, Zinc Pulse (for galvanized sheets)

• Aluminum and silicon-based brazing

• MTS-CO₂ / Normal-CO₂

• S-AWP – Super Active Welding Process for various material types

Go beyond the limits of conventional welding. With Panasonic TAWERS, you benefit from automation, stable quality, and advanced technology—all within a single, integrated system.

TAWERS – Intelligent Welding Technology from Panasonic – Features (Not Exhaustive)

Weld Navigation Software - for easier welding parameter setting

LIFT START / LIFT END

At the start and end of the welding process, the robot quickly lifts the welding torch. By coordinating the robot movement with the specified welding parameters and the wire feed control, quality and cycle time are improved.

TORCH ANGLE DISPLAY

Real-time tilt angle display (work angle, forward/backward angle)

Helps ensure precise weld bead creation and faster programming.

OPTIONAL SENSORS

AUTO EXTENSION

(For MIG / MAG / TIG welding processes)

It is a function that absorbs height wise error and distortion of the work (if occurred) by adjusting the torch position to attain stable welding. Therefore, this function is useful for welding of a work that may be distorted by welding heat or welding of eccentric pipes.

TOUCH SENSOR

The touch sensor detects deviation between the taught weld start point and the actual weld start point and corrects.
