Semi-Automatic Parallel Seam Sealer


Product Description

Packed with advanced features, the Windows® based SM8500, reliably performs hermetic resistance welding, brazing, and soldering processes on a variety of metals, alloys, plated materials, and solder pre-forms. SM8500 can be operated as either a stand-alone unit or fully integrated into a glovebox enclosure for a complete closed-loop hermetic sealing process for applications including optoelectronic packaging, semiconductor packaging, transistor outline package welding, and more.

Key Features

  • Parallel Seam Sealing System – SM8500
  • Utilizes the advanced HF25 25 kHz closed-loop feedback weld power supply.
  • Programmable electrode force enables user to optimize both force and energy.
  • Indexed electrodes ensure extended, even wear providing superior results.
  • Position-based weld pulses provide increased or decreased energy at part corners reducing corner leaks.
  • Electrode roll-back feature facilitates electrode release from light weight parts.
  • Circular mode seam sealing allows processing of round parts.
  • Operates as tacker only, sealer only, or combined tacker-sealer
  • Four-pass welding feature starts weld from center and welds to the part corner – for large part sealing
  • Set different energy levels for each axis welded for higher yields on rectangular parts
  • Many tacking options – tack centre, four-side tacking, multiple tacking
  • Real time monitoring of weld inhibit inputs such as moisture, oxygen, and helium levels
  • Unlimited weld schedule storage
  • Lid hold down feature assists tacking process
  • Multiple weld schedule chaining feature
  • Optional CCTV camera available to assist the operator for improved lid placement
  • Batch reporting option
