welding technology

The optimal alternative to soldering technology


Arc welding

The pulse micro arc welder, for applications where precise control and high repetition accuracy are required. The unit can give an accurate current pulse and time pulse. A closed-loop control system ensures stable output power regardless of fluctuations in the mains or temperatures or cable lengths.

Resistance welding

HF DC welding technology.
The HF DC control for highest demands, combining all the established advantages of linear DC devices with the advantages of compactness and performance.
Depending on the energy requirement, the switching frequency (25 - 100 KHz) and thus the control speed is automatically adjusted. This means high flexibility and repetition accuracy over a wider energy range is guaranteed.
Large colour monitor displays all process-relevant variables in graphical and numerical form, including error indication.
