MAX-40 B/D
The Max 40 B/D is a lightweight (< 8 kg) and powerful extruder, designed for welding plastics up to 30 mm thick in field work and containers with difficult access.
High capacity for significant thicknesses without losing maneuverability
Although it weighs less than 8 kg, it allows welding plastics up to 30 mm thick, making it ideal for applications that require robust materials without carrying a heavy machine.
Designed for hard-to-reach places and prolonged work
The “B/D” version uses side preheating and offers a variable handle and multiple clamping points, making it easier to weld inside containers, confined spaces, or complex areas. It also features a standby mode that reduces noise and energy consumption when not in use.
Precise results and professional cleaning with every pass
The brushless motor and integrated LED lights allow for continuous work with less wear, better visibility, and high-quality finishes that are noticeable.
Efficient for demanding production or maintenance
Thanks to its welding flow rate (e.g., up to ~3.9 kg/h with Ø 5 mm), it is suitable for both light manufacturing and on-site maintenance installations, providing speed without sacrificing quality.
Welding flow up to 3.9 kg/h with Ø 5 mm rod
Compatible with PP, PE and PVDF materials
Designed for thicknesses of 8-30 mm

TIPS MAX-40
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.
