SIGMA 500 Series

  • Automatic pocketing with electronic sizing from 20-145mm

  • Automatic overlaps, reinforcements and available guide for spline/ keder/ zipper

  • Available pressure control for perfect welds

The Sigma 500 series of impulse welders offers more flexibility and range than the 300 series.
Featuring automatic hemming from 20mm up to 145mm with electronic size adjustment, the 500 series welders have the broadest range of selectable sizes of all welders on the market except the Sigma PRO series.

The 500 series includes automatic hemming, overlaps, reinforcements and integrated guide for zippers, splines, or keders.

With the most advanced set of welding features available, including 10 cycles and optional pressure control, you can customize an almost limitless amount of individual and group recipes to achieve the perfect weld results every time.

Operation is easy and convenient on the largest touchscreen available on the market that features real-time feedback as well as color coded LED’s to offer visual indicators to what the machine is doing.

Available from 4m to 8.4m lengths with bar thicknesses from 6-24mm, the 500 series impulse welders from Sigma Engineering offer the greatest ROI on the market.
