Miniature welds are highly sensitive to even the smallest heat profile fluctuations during the resistance welding process:  overheating deforms and destroys parts, while under heating results in a weak, unacceptable bond.   Precise control, therefore, is required to achieve consistent, reliable welds. The HF27 high frequency inverter welding machine achieves this level of control by precisely managing and monitoring both electrical AND mechanical weld parameters in a completely closed-loop process.  HF27 can address a wide range of applications including sensitive medical device components, solar cells, automotive electronics, battery tabs, battery pack assembly and more!

HF27 may be used in conjunction with one of our many weld heads as a single operator benchtop unit and is well-suited for integration into semi or fully automated resistance welding systems.  AMADA MIYACHI specializes in designing and building fully integrated, semi-automated and fully automated resistance spot welding machines.  See our Integrated Systems brochure for more information.
