Synergic MIG welding units designed for robots

The faster welding pace of MIG welding robots - often using multiple short runs - demands extremely rapid communication between robot, weld units and control system.

Kemppi will strengthen its position as a manufacturer of welding automation equipment with the launch of the new KempArc Synergic product range.

The new product range is to the last detail developed for the special requirements of welding automation.

The demands set for robotic welding equipment differ in many respects from those made of manual welding gear.

The welds are typically short, lasting only a few seconds, and a welding robot can make thousands of them each day.

Such a fast welding pace demands extremely rapid communication between the robot control system and the welding equipment connected to it.

In the development of Kemppi's new KempArc Synergic product range, the emphasis has been placed on fast reaction speed and reliable wire feeding, both of which play a key role in improving welding automation productivity.

Even a slight improvement in reaction speed is multiplied many times over, yielding great improvement in the productivity of the whole process, in which the robot ignites and extinguishes the arc thousands of times a day.

* Integration and the latest Kemppi technology - the KempArc Synergic product range includes the latest Kemppi technology especially applied to welding automation.

The product range includes a control panel, three power source options, and the amazingly small DT 400 wire feeder equipped with the new DURATorque mechanism with metallic feed rolls.

The wire feeder itself is not much larger than the mechanism within, so the wire feed unit moves smoothly and easily with the robot arm.

The DURATorque mechanism equipped with metallic feed rolls ensures a constantly smooth and reliable wire feed.

Also, the power sources are small and compact devices with a built-in interface.

In developing the KempArc power sources, it was considered important to create a system where the customer doesn't have to acquire separate equipment for the robot system just to be able to use high-power welding once in a while.

Two KempArc power sources can be joined with a parallel connection to form a single high-power unit if power of more than 500 amperes is needed for welding, e g, exceptionally thick materials.

With a separate wire feeder, the power sources can be used in manual tack welding also, so the combinability of the elements in the KempArc system makes it exceptionally versatile welding automation equipment.

* Software components enhance the productivity of welding automation - the KempArc Synergic system includes various synergic curves.

Stored in the memory, these are combinations of welding parameters that allow the welding machine to find the optimal values for use in specific welding tasks.

The synergic curves and the 90 memory channels of the KempArc system provide assistance to the programmer of the welding robot, as they allow selection of the plate thickness from the control panel, after which the machine can find the right weld parameters automatically.

Also, the new welding process 'AAA', designed especially for the needs of automated welding, is being developed for the KempArc Synergic system.

* About Kemppi - Kemppi Oy, founded in 1949, is a well-known supplier of top-quality and productive welding solutions.
