Profibot ® CNC Welding Robots

Affordable and reliable robot welders with easy "teach-in" controller

Cartesian Robots

Cartesian robots, which are also called linear robots or gantry robots, are industrial robots that work on three linear axes that use the Cartesian Coordinate system (X, Y, and Z), meaning they move in straight lines on 3-axis (up and down, in and out, and side to side).

Cartesian robots are a popular choice due to being highly flexible in their configurations, giving users the ability to adjust the robot’s speed, precision, stroke length, and size.

Cartesian Robots are one of the most commonly used robot types for industrial applications.

We defined that ANY machine operator should be able to use our Profibot®.

Our concept is meant to make turning more accessible, simple, profitable and affordable.

Super Easy "Teach-in" Controller

More simple is not possible

Joystick "teach-in" robot controller

More simple is not possible

"Make it simple" is the base of our Robot controller

Our CNC Robot Welder can start a new series in a matter of minutes.

The complex pendant controller every robot maker is using is a huge bottleneck in most of the workshops. We did avoid this problem.

The challenge for Us consisted of redesigning the interface of the Robot. Rather than a pendant with hundreds of unknown buttons, that has been the standard since forever, we took a very innovative decision to use an interactive screen with very simple graphic interaction, to control the robot-movements.

This means that the Robot Welder can be used as standard MANUAL Welding machine, controlled by joy-stick, to make one single piece manually without interaction of the robot program. All manual movings made by the joystick can be memorised and the controller automarically generate the program for the robot controller.

By interactive programming the operator take one of the pre-programmed movements from the controller with one button-click and the operator need only to fill in the values of the different stop/start points in the interface. The sequences of welding movements to finish the part are done one by one by with controller supported conversational dialogue. More Simple is not possible!

No robotics experience is required for the robot controller. Our robot is already completely pre-programmed, so that the operator only needs to enter a few parameters.

This means a new series can be started in a matter of minutes on our Robot Welder.


Cartesian CNC robot welder

A Cartesian robot welder consists Standard of three linear axes and one rotary axes (PROFIBOT®-IV), featuring high strength, fast response, high positioning accuracy, flexible orientation/angle adjustment, high end load and wide range compared with the conventional articulated robots. Optional, the Robot can be equipped with 1 (PROFIBOT®-V) or 2 (PROFIBOT®-VI) extra rotary axis, to increase the flexibility and /or productivity

With our dedicated controller you achieve teaching, offline programming, automatic location and complex wing, fitting with various types of sensors for intelligent job; suitable for the most complex welding and/or cutting jobs.

The PROFIBOT® CNC Robot welder can be customized on demand. 

Our Cartesian robot welder adopts 4/5/6-axis transmission to achieve wide range adjustment of the position of the torch through line feed of gantry truss along axis-X Y, Z, suitable for welding of a variety of large-medium-sized work-pieces, wide range, high applicability; to achieve adjustment of angle of the torch via rotating of the two rotary axes and following of other axes, enabling flat welding, fillet welding, vertical welding, overhead welding, welding of plane curves and space curves etc. The servo motor planetary reducer is used as the transmission, featuring steady accuracy. A handheld Teaching Pendant with joystick is set for teaching programming for work-pieces.


  • TEACH:The control system can send action sequence, motion speed, welding parameters, location and other information to the robot in advance via the Teach Pendant using certain methods, which are recorded in the memory, and can be played back as required;
  • Location:After replacement of work-pieces in mass production, the robot will detect the position of the work-piece and calculate the deviation from the teaching work-piece via ON/OFF of current of the barrel or the wire and work-piece following the predetermined program, in order to find the correct working position;
  • Swing:The system can perform welding with weaving in all directions through fitting of motion of various axis, wide weld, high efficiency; You can choose sine, triangle or circular welding with weaving, with convenient adjustment of weaving frequency and amplitude;
  • Anti-collision:The torch is fit with an anti-collision sensor. As collision with an obstacle, the robot will automatically stop. After removing the obstacle and the alarm on the Teach Pendant interface is clear, the robot will continue to run, ensuring personal and equipment safety.


This equipment is suitable for welding of steel, gear box, equipment base, bridge beams, carriage side, container side walls, all kinds of intersecting lines and other large parts, and can form welding lines combining with other equipment or facilities.

10 Advantages of Robotic Welding

Welding automation offers numerous benefits for companies of all sizes - from improved productivity and weld consistency to lower costs for production, labour and materials.

No longer are robots just suitable for large manufacturers but smaller to medium size businesses also stand to benefit by implementing a Robotic Welding technology solution.

1. Increase in Productivity

With a robots ability to process welded components three to five times faster than humans by operating continuously, withstanding a greater arc on-time and moving quickly between weld joint positions, a robotic welding system can provide substantial increases in output.

2. Consistent and Repeatability

Manual welding requires a high level of skill as well as concentration to achieve consistency and repeatability. A robotic welder can continue to perform precisely the same weld cycle continuously, 24 hours a day, seven days a week.

3. Flexibility

Manual welding processes require multiple jigs which are swapped out with each production run. Robots can save valuable time and eliminate tool changes as grippers can grab any part regardless of size or shape, position it on the assembly, and hold it tight during the welding process

4. Safety

Numerous safety risks exist for welders such as electric shock, exposure to gases and toxic fumes, and welder’s flash burns to the eyes cornea. Robotic welders have proven themselves in reducing the number of accidents to workers in the metal fabrication industry with the number of injuries reported to Safe Work Australia reducing each year.

5. Quality

A robotic welder can achieve superior quality by ensuring the correct welding angle, speed, and distance with repeatability of accuracy of (+0.04mm).  Ensuring that every single welding joint is consistently produced to the highest quality significantly reduces the need for costly rework.

6. Labour

With a shortage of skilled workers, robotic welders have helped to overcome this issue.   Whilst manual welders will still be required for jobs which have a high degree of customisation, a robotic welder will alleviate issues in busy times by reducing additional hours and the need to hire and train extra staff.

7. Reduce Consumables

With manual welding, the size of the weld is determined from the operator and could result in a larger weld than required.   Robots are programmed to always weld to the correct length and size of the joint requirement, providing significant saving over time.

8. Reduced Production Costs

Through improvements in quality, consistency and productivity a robotic welding system can deliver parts at a reduced cost. Further saving can also be made through reduced energy consumption and consumable costs in addition to lowering workers compensation and insurance costs.

9. Reduction in Weld Distortion

Distortion in a weld occurs from the expansion and contraction of the weld metal and adjacent base metal during the heating and cooling cycle of the welding process.  Robotic welders are tuned to correctly size the weld for the requirements of the joint, minimise the amount of weld passes and complete the process with speed to minimising the heating of the surrounding metal that can expand and lead to distortion.

10. Increased Competitive Advantage

Implementing a robotic welding solution can set companies apart from the competition by allowing for faster completion and delivery of products whilst ensuring consistent quality.
