SIGMA 700 Series

  • Dual, Integrated guides for spline/ keder/ zipper

  • Built-in tunnel guides for batten pockets

  • Pressure control for perfect welds

The Sigma 700 series of impulse welders takes all of the features of the 500 series and adds a second, integrated guide. T
he 700 series still includes automatic hemming from 20 to 145mm as well as automatic overlaps, reinforcements and integrated guide for zippers, splines, or keders for two separate sizes.

With the most advanced set of welding features available 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 700 series impulse welders from Sigma Engineering offer even more built-in features for the most detailed and complex welds.
