Wedge-It
The Wedge-It is Munsch's original automatic wedge welding machine, combining robustness, performance and versatility to weld plastic sheets from 1.0 to 2.5 mm with industrial speed and quality.
High production capacity for industrial sheets
This equipment can process sheets between 1.0 and 2.5 mm thick with 6 pressure rollers, making it ideal for installations where volume and continuity of welding are key.
Proven and durable design for professional use
It is “the original” of Munsch wedge machines: a reliable model, with a robust design and the possibility of changing the copper wedge to stainless steel for welding PVC, which makes it very versatile.
Simple control with great features
It allows you to pre-adjust all parameters, switch between 220V and 110V, and work with different materials without complications. The user obtains quality finishes without the need for complex adjustments.
Ideal for demanding industrial environments
Designed for applications in geomembrane construction, civil engineering, sealing of plastic sheets, where airtightness, resistance and equipment that does not fail are required.
Sheet thickness: 1.0 – 2.5 mm
Wedge change: standard copper, optional stainless steel for PVC
Dual voltage: 110V / 220V

USES AND APPLICATIONS
- Equipped with 6 pressure rollers, which ensures uniform contact during welding.
- Simple and robust design for continuous industrial operation.
- Transport trolley included, making it easy to take to the construction site.
- Wide range of materials: PE-HD, PP, (and with special wedge) PVC.
- Suitable for intensive sealing applications on plastic sheets, geomembranes, and industrial roofs.
MORE DETAILS
- A good choice for customers already working in civil engineering, water treatment, plastic barriers, where reliable and proven equipment is required.
- If the customer needs something lighter or for thinner sheets, they could look at the “Micro” or “Multi Eco” models, but if what they are looking for is a solid professional standard, this model covers it ample.
TIPS CUÑA-IT
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.
- Preventive
Applied by Munsch Engineering
- Preferably every 350 hours of use.
- Corrective
