Leister UNIPLAN 500 40mm 230V or 120V industrial fabric welding machine


The UNIPLAN 500 is a more powerful fully automatic digital hot-air welding machine suitable for making tarpaulins, banners, marquees etc with easy to configure digital settings for speed and temperature. Able to weld at up to 16m/min and now with up to 40mm seams

Estimated Delivery: Next Working Day (order before 3pm)


The New UNIPLAN 500 Industrial Fabric Welder from Leister Welds Tarpaulins, Banners, Tents and PVC Coated Materials

Available in 230V or 120V, the all new UNIPLAN 500 industrial fabric welder from Leister has been radically redesigned to make it faster (up to 16m/min), easier and more intuitive to use when welding industrial PVC fabric. Now also comes with the ability to weld up to 40mm seams.

Leister's reputation for designing industrial quality machines is second to none when it comes to welding PVC coated or reinforced materials such as those used in making PVC banners, lorry tarpaulins, manufacturing marquee’s or inflatable structures such as tennis domes or sports hall coverings. The machine is suitable for floor or bench top operation when welding technical textiles and industrial fabrics .

The new UNIPLAN 500 now comes with an integrated material lifter and an automatic swivel-in control for the nozzle (controlled at the rear of the machine) to make it safer, easier and more reliable for the user.

In addition the introduction of a cleverly designed sliding swivel caster, that can be moved out of the way of obstacles like grommets, hooks or other accessories, makes it easier to avoid potential issues with the welding process.

Faster production processes are now achievable as the UNIPLAN 500 can quickly be changed from overlap welding to pipe or hem welding in one easy step. Another clever innovation is the introduction of an adjustable starting delay / preheat which means the welding process can be accurately adapted for light or heavy materials.

A new integrated weight section directly over the pressure wheel comes as standard on the UNIPLAN 500, as does the inclusion of 2 x 1.25kg. Also standard is a rotatable large handle for ease of lifting and guiding. A longer handle is available as an optional extra.

As with all the latest Leister automatic welding machines the UNIPLAN 500 is a digitally controlled machine with the latest E-Drive control interface with easy to configure digital settings and controls for drive speed and temperature. All control settings are closed loop for accurate welding.

Welding parameter settings can also now be stored for fast future setup (UNIPLAN 500 only). It also comes with a maintenance free brushless motor.
