Wedge-It Multi
The Wedge-It Multi is an automatic wedge welder designed to work with plastic sheets from 1.0 to 3.0 mm with integrated logging data — ideal for professional geomembrane and lining applications.

Maximum versatility for medium-thickness plastic sheets
Capable of welding materials between 1.0 and 3.0 mm thick, the Wedge-It Multi covers a wide range of applications, from geomembranes to industrial linings and plastic roofing. Its all-rounder design makes it ideal when you don't want multiple machines.
Data logging and digital control for greater reliability
It includes a menu screen, parameter presets, and SD card data storage for later analysis. This is key when weld quality documentation is required for audits or certifications.
Compact and maneuverable design for construction sites and workshops
Although powerful, its size and control wheel make it manageable, facilitating work in industrial environments where space or mobility are a challenge.
Ideal for demanding applications requiring airtightness and traceability
Perfect for projects where welding must meet high standards, with data recording, technical materials and compliance with regulations in civil engineering, water treatment or construction.
Material thickness: 1.0 – 3.0 mm
Material compatibility: PP, PE-HD, PVC (with appropriate wedge)
Integrated data logging (SD card, software)
USES AND APPLICATIONS
Power consumption: ~ 1500 W
- Design with included trolley or carrying case
MORE DETAILS
- Recommended applications: welding of geomembranes, plastic roofs, industrial cladding sheets where uniform joints and traceability are required.
TIPS WEDGE-IT MULTI
ELECTRICAL CONNECTION
New equipment has a European connection; ideally, you should have a European female connector. If that's not the case, we'll show you how to connect it to the American system.
To connect it, we share the following specifications:
IMPORTANT:
- Consider the NEMA in which only the physical ground should be connected (Image).
- Ideally, in the industry, you should use a separate thermal switch from your load center (the amperage range can be from 20 to 30 Amps). If you have any questions, please contact technical support.
GENERATOR CONNECTION
In the Americas, generators have a 240v female outlet, and you must identify the NEMA.
Important:
- Once you have identified the NEMA, you must obtain the male that corresponds to the NEMA.
- You just need to connect L1 and L2, which is the equipment voltage, and add "T" ground.
- When purchasing a generator, you should pay attention to 3 important electrical characteristics:
- Watts
- Voltage
- The most important one is how many Amps it delivers per phase.
We recommend having an extension where you can have a MULTI-CONTACT module so you can connect your equipment independently.

MAINTENANCE
How often should you perform maintenance on your equipment?
- Deductive
Applied by the operator
- Tighten the connections periodically.
- Clean the filters daily.
- Purge the device every time you finish your shift.
- It is important to purge with natural polyethylene welding every month.
- Before connecting your equipment, you should leave your generator running for ten minutes to allow it to stabilize.
- Once 10 minutes have passed, every generator should deliver 235 to 240 volts.
- Before doing this, we suggest you always check your line (L1) to ground with a multimeter and L2 using the same procedure; each phase should deliver above 110 volts. If it is less than 70 volts in any of the phases, do not connect your equipment under any circumstances; send your generator to a service center.
